Bear Vault 450 Review

Bear Vault Solo 450
I purchased the Bear Vault 450 to use on my National Park backpacking trips this summer.  I selected this model because it would fit inside my Gossamer Gear Kumo backpack while satisfying the National Parks requirement to protect bears (and mini-bears) by securing food and smellables.
My 36 liter/2200 cubic inch backpack was chosen 4 years ago for carrying light weight camping equipment on mostly overnight backpacking trips.  The larger bear proof containers will not fit my backpack.  The BV450 does fit just fine, with a little room to the side for my first aid kit and small items like my headlamp.  The bear box sits in the bag on top of my sleeping bag, clothes and jacket and on top of the trash compactor bag I use for water proofing them.  I did find I cannot load the top pack flap pocket with the BV450 inside, or I will have to unload the pocket every time before removing the BV450, a minor inconvenience.
The clear blue polycarbonite construction makes it easy to see the contents.  It is 8.7 by 8.3 inches and holds 440 cubic inches/7.2 liters inside it.  The Vault can also be useful for hauling water, washing dishes and clothing, and using as a table or chair.  If you are curious about it being tampered with, add a bear bell inside at night.  Tool-free is good news to my ears, read more about opening the jar below!  Some unexpected good news, crackers, bread and bananas won't get smashed!


I carry all my cooking gear, plus food, hygiene and other smellables inside an Op Sack, inside the BV450.  I used these Op Sacks for a few years to carry my food without any animals getting into my backpack.  I can also use them to separate food items from clothing items.  There is also another Op Sack for trash, and a few Zip-Loc bags for repackaging food stuffed inside.  There is also lots of room for some clothing, if I needed to carry any.
So far, there has been plenty of room to carry all this, both inside the pack and inside the bear box.  My one-freezer-bag dinner and 3-4 breakfast bars plus fruit, 2 tea bags and other snacks will easily fit.  The BV450 is supposed to carry 4 to 5 days of food, so I'm only currently using part of one day's supply.  On one overnight trip, I also fed a hiking partner dinner and breakfast and still had plenty of room.
As a test, I filled the BV450 with 6.5 days of food.  I may be able to get a full 7 days inside the container, but that is plenty more than 4 to 5 days of food.  The trick is removing all the packaging and squeezing the air out of all the freezer bags and Zip-Locs.  That's leaving the stove in the pack too, but including the hygiene and smellables inside the vault.  With carrying a full days worth of food in an Op Sack, you can get an easy 7 to 8 days of food with you, just hang that extra day for one night for safety.
The Bear Vault 450 does claim to weigh 2.1 pounds.  On my scale it weighs slightly less than that at 33.1 ounces or 938 grams.


While increasing my overall backpack weight by a bit more than 2 pounds, when you also add in the extra weight of my butane/propane stove and heavier butane fuel canister (National Park requirement for an on/off switch on a stove), plus my 2.5 pound backpacking tent, I am pushing the 25 pound maximum limits of my backpack when also carrying 4 liters of water on dry camp overnights.  The backpack weighs in at a comfortable 20 pounds with only 2 liters of water and I don't realize I have it on until I near the maximum limit of 25 pounds.
While camping, I had no difficulty opening the bear box until one cool morning where it hurt my fingers to press the collar in far enough to open it.  Using the edge of my pocket knife handle to depress the tab rough area far enough in to clear the latch quickly and painlessly opened the top.


The latch mechanism works using 2 tabs that are part of the lid that have to be individually depressed in order to clear the latch.  The idea is bears shouldn't be able to figure this out.  I did find the cylinder difficult to hold still while depressing the tabs on the lid.  Holding it between my legs seemed to help.  I read someone's account that said to watch how the latch works to better be able to use it, and they were right.
When camping in the Great Sand Dunes, I noted I should not set the lid down into the sand.  I did learn that a few grains of sand or dirt would make it difficult to open, so I kept the lid and jar clean and had no problems.  The lid can serve to support your cooking stove, hold food prep items and function as a bowl in an emergency, just remember to keep it clean.
The BV450 makes an OK camp chair to sit on while eating since I don't carry one.  Just be sure the lid is screwed all the way on and latched first.


At night I stored the box 100 yards from my tent. That's 120 steps away.  My concern is the BV450 is a cylinder and with the round sides it can roll a long way if disturbed.  I have thought about using a piece of rope to secure it to a tree or rocks so it won't roll away with my breakfast in it.  I would hate to lose it.
Aside from the weight, using the Bear Vault 450 was easy and intuitive to open and latch.  For my use, I could get by with something more the size of 2 liter bottle, but wanted 1. something that I could also use to carry up to 5 days of food and 2, to own only one bear container.  Overall, I think the Bear Vault 450 is a good product and will give me many years of use.


I do not know this for sure, but I expect the powers that be to increase back country requirements for carrying bear containers.  Areas like the Appalachian Trail, National Forests, Wilderness Areas and the like may some day require bear container use.  I figured I would get used to using one now, so it wouldn't be burdensome to me later on.
I suggest taping a business card inside to help with identification in a group or if the canister gets rolled down the mountain.  I purchased this with my own funds.  They run about $65 at REI.

Summer is here, let's ULBackpack!

Me (reflection) Backpacking at Green Swamp last year
What I want to talk about today is Ultralight Backpacking, and what things you need and what you need to know to get out there.
The base weight of my gear is currently 9.5 pounds.  That includes the tent, sleeping pad, quilt, clothing, spares, cook gear, first aid, grooming, empty water bottles and the the pack itself.  That is everything I carry EXCEPT food, fuel & water.  I pack about 1.5 pounds per person per day (ppppd) for food, plan for 4 ounces (3 Esbit tabs + 1 spare) of fuel used per day and typically carry 2 liters of water at a time, unless the route requires I carry more between refills (water weighs 2.2 pounds per liter).
Let's start with a backpack.  For up to 3 days, a 35 liter/2130 cubic inch backpack is more than enough space for carrying your ultralight gear.  Some UL Backpackers can hike many more days with this pack.  Aim for a pack that weighs about one pound.  Expect a total loaded pack to weigh under 20-25 pounds including food, fuel & 2 liters of water.  Be sure your backpack can carry the weight before you overload it.  My pack is the Gossamer Gear Kumo and it is very comfortable for all-day long backpacking.  The GoLite Jam is also a very good choice in both the 35 & 50 liter sizes.
Gossamer Gear Kumo - 35 Liters, 1 lb.
For much longer hikes and areas where bear-proof canisters are required, a 50 liter/3050 cubic inch backpack is plenty of space with room to handle resupply stops and 5-7 days of food.  This should weigh about 2 pounds.  You may carry up to 35-40 pounds of gear in your pack for a few days including food, fuel & 2 liters of water.  This would be the right size pack for a through-hiker on the Appalachian Trail.  I like the REI backpacks like the Flash 45 shown below, but there are several other backpack manufacturers you should look at before deciding.  Just remember to keep the weight of a 50 liter bag to as near 2 pounds as possible.

REI Flash 45 - Lg 50 Liters, 2 lbs 3 oz.
Do carry enough clothing to keep warm at night like a polar plus jacket or sweater, long underwear, and a hat.  Remember the temperature drops 3.5 degrees for each 1000 feet you gain in elevation.  So if your trail will climb to the camp site at 3500 feet, and if it is forecast to be 40 degrees tonight down here at sea level, your temperature would be closer to 28 degrees at camp, cold enough to freeze your water bottles (or 3.5 degrees x 3.5 for each 1000 feet).
So with my ThermaRest Alpine 35 degree blanket (quilt) and wearing all my clothing, I would be quite warm and comfortable.  A 20 degree bag would be overkill in the summer and way too hot and sweaty for most nights.
Let's talk about water.  I always plan to carry at least 2 liters of water, unless I am familiar with the water sources along the trail.  For most backpacking trips I have the ability to carry 5 liters at one time using a combination of my two 1 liter Gatorade bottles outside the pack in the side pockets, 2 Platypus 1 liter soft water bottles inside the pack plus 1 liter of unfiltered water in my Sawyer filter bag (filter later).  While that is 11 pounds of water (more than my base weight), it is a full days supply of drinking water for me, counting cooking and cleaning needs.  That would cover me if I had to "dry camp", as long as water was an hour or two down the trail in the morning.  Desert travel may require more, Northeastern US travel may require less.  Just remember it is as important to carry enough water as it is important to not carry too much water.  Research your route and talk to others who have backpacked there recently (last week, this time last year) to get a hikers take on available water flow.  Remember the words from Andrew Skurka, who said that if you reach the next water source and still have water in your pack, you have made a mistake.
To review what you need to know:

  • Your base weight is the total weight of everything in your pack EXCLUDING food, fuel & water.
  • Plan to carry at least 1.5 pounds (ppppd) food per person per day, maybe more.
  • 1-3 night backpack size 35 liters and weighs 1 pound.
  • 5 day+, bear canister capable, through-hike backpack size 50 liters and weighs 2 pounds.
  • Temperature drops 3.5 degrees each 1000 feet of elevation gain.  Carry adequate clothing and plan to sleep in everything you have when it is cold.
  • Water weighs 2.2 pounds per liter.
  • If you don't already know, learn how much water you need to drink per day, include cooking & cleaning.
  • Have the capability to carry one day's supply of water, talk to previous hikers and study the maps and make your best guess at the next water source.  Try not to overload yourself if it is unnecessary.

Next week, we'll cover more about what to expect when backpacking.

Spring 2013 Gear List

I weighed everything again and finished my gear list today.  The list is included below.  It all fits into my Gossamer Gear Kumo backpack with a little room to spare.   Depending on the weather the week I actually plan to go camping, some clothing like long underwear, and a hat may be needed.  This is Florida, but the nights may still be cold.  We are too far out from the trip date to determine that at this point, so we'll go with the average highs and lows for the area near near where we'll be camping.
I am planing to join with a Sierra Club group from Tampa, who will be camping in the Green Swamp Wilderness Preserve West Tract in the Richloam Tract.  The camping site is just northeast of the Withlacoochee River, but we will not be camping on the river.  The idea is to hike into the back country and camp overnight at a primitive campsite.  We'll hike out the next day and head home.  An easy, simple, one-overnight weekend trip with a short hike on either end.  It is about a 2 hour highway drive from Orlando.
My friend, Robert, says these good people we are going with are mostly traditional backpackers, so we will be the ultralight travelers in the group.  Robert backpacks with this group often.
Green Swamp Wilderness Preserve West Tract.
For camping in the Green Swamp area, northeast of Dade City, FL we are looking at an average high temperature this month of 81 degrees, a low of 56 degrees and a possibility of rain.  Looking at the week-long-range weather forecast for that time, the area is expected to have a high temperature of 77 degrees with a low of 48 and partly cloudy, with 81 degrees and sunny skies the next day.  We will be camping northeast of town in sand hill and pines.  In Florida, this month has always come in like a lion and gone out like a lamb, so I expect the weather report may change.
My low weight "goal", while keeping me warm and safe, was to reach 10 pounds, and I'm close enough to that.  I have read that the ultralight base weight both starts at 10 pounds, and at 12 pounds.  With just a two pound difference, why really care?  Over time, the loaded backpack weight will fluctuate some, and that is OK.  I'm not "gram crazy", at least not yet!
My packing list adds up to a base weight of 11.36 pounds.  Rounding, that's 11 pounds before water, food and fuel are added in.  We will not have to carry water for the overnight, as there is a pond nearby. With about 2 pounds of food (1.5 pounds per day plus snacks), 4.8 pounds of water (2 liters) and a couple ounces of Esbit fuel tabs added, that would put me near 18 pounds for the fully loaded backpack.  Nice!
By category, I am at just over 1 pound for my backpack system, 2.5 lbs for the sleeping system (less clothing), 4.27 lbs for the tent system (double what it should be).  The cooking system is at 1 pound, the repair & backup kit is at 1/3 of a pound, the health kit is under 1/2 pound, and my clothing is at 1 and 1/2 pound, most of which I will be wearing for sleeping.
Now that 11.4 pounds above includes my 4.27 pound Alps Mountaineering Mystique 1.5 tent.  It seems the tent weight had suddenly increased from when I weighed it before, until I found that I didn't previously weigh all the tent stakes or add in the footprint (oops).  This is a nice tent and it is well made and built heavy-duty to survive Boy Scout-aged users.  It is very waterproof and lightweight in the older sense, but it is now considered a heavy tent in the ultralight backpacking world.  My long term goal is to reduce my tent weight by at least 50% by purchasing a new tent, and I will do that at the first opportunity.  Then I would be closer to 9 pounds base weight, which will be really cool!
Another way I can reduce weight is to repackage some of my health items into smaller containers, like the Hydropel and the Wilderness soap.  We're only talking about reducing a couple of ounces here.  I don't feel that I will need the full package of either one for a single overnight trip, and will make that change soon.
For heavy weather, I may also have to add in rain pants and some of the warm clothing listed above.  My Kumo is good to carry a total of 25 pounds, so at a few pounds under that weight I should be just fine.  Much, much better than the 60 pounds that I used to carry in the "old" days.  For much longer duration trips I will need a larger backpack to carry my gear, like the REI Flash 45 I am looking into now.
My gear is packed with the sleeping pad folded into quarters in the back outside pocket of the Kumo backpack, next to my back.  The tent stores vertically, in the outside front pocket.  The sleeping quilt is inside the pack at the right bottom with the clothing and repair kit beside and on top of the sleeping bag.  Then the cooking gear, health kit and food are in a Granite Gear air zip bag, laying sideways on top.  Outside and on top of the trash compactor liner is the rain jacket.  Two soft 1 liter water bottles are in each side pocket with the tent poles on the left side.  Tent stakes and footprint are in the front pocket along with the water filter and tent.  Snacks, camera and my "pocket items" are on me.
So here's my packing list for you backpackers, with the food and water weight included.  The Gossamer Gear Kumo pack weight includes the hip belt, but no belt pockets.  My apologies, the columns may not line up on your screens.

More Backpack and Quilt Minutia

Gossamer Gear Kumo
I kept thinking about my previous Backpack Minutia post where I had selected a Gossamer Gear Gorilla, a 50 liter ultralight backpack, and I could not shake the fact that most of the time in the near future my backpacking trips would only last an overnight to three overnights, 5 nights at most, perfect for a 36 liter pack.  So what would I do with all that available through-hiker room in the Gorilla backpack?  So I kept looking for a smaller day pack that could easily handle a 25-pound load.
MLD Burn
I may have found just that with the Gossamer Gear Kumo.  Kumo is Japanese for "Cloud".  It is built on the Murmur frame but is made with lighter and tougher materials like 140 denier Dyneema Gridstop and is designed to carry the 25 pounds my scale and research says I'll need for up to a 5-day trip.  It also has a zipper pouch on the top pocket and 3 outside pockets.  Only the side-cut of the back pocket concerns me (maybe too short to securely stow my planned tarp/tent).  This is also mentioned by other reviewers but that may or may not be a real issue-we"ll just have to see.  Gear reports have been very good like this one here.  At 14.65 ounces for the large size, the pack weight is great and the load capacity is 2200 cubic inches or 36 liters.  The Gossamer Gear website says both "We recommend the Kumo Superlight backpack for total weights below 25 lbs." and "25 lb. maximum carry capacity, but 20 lbs, is better".  In my case, that 5 lb. difference before getting "better" being mostly estimated water weight for long trail slogs between refills.  Overall, the pack seems to be able to handle my planned gear load without lots of "empty space" to have to strap down and would be a significant weight savings over the 27 ounce Gorilla pack.  The cost is OK at $55 less than the Gorilla and when the time comes that I need the additional 15 liters of gear space for a season-long through hike, I'll just have to upgrade.  And who knows what the marketplace will have to offer then?
GoLite Jam 35
Other packs I'm looking at include the MLD Burn, a 2300 cubic inch pack in the same price and feature range as the Kumo.  Here's a review.  It certainly has a better main outside pocket, can handle much larger loads and appears to carry greater weight.  By adding two side pockets on the waist belt it improves the functionality and could act (for me) more like a Gorilla pack in a smaller package!
Also, the GoLite Jam 35 is a good pack for the money at $99 on sale.  I do not like the large fabric rear pocket as much as a mesh pocket, but otherwise the pack is a good deal.  At one pound 10 ounces it is a little bit heavy but I can surely use the $65 dollars to buy more gear! Here's it's review.  It is out of stock today but that may change soon.
There are a few packs in the 36 liter size from manufacturers like Gregory, Osprey, Deuter, REI and others, some at better prices, but none at one pound or less total weight.  And that is what I just have to have, an ultralight backpack.
So, on to Sleeping Quilt Minutia...My Florida backpacking experience has mostly been with 20 degree sleeping bags where I sweated year-round.  Once I left the south I found the bags worked better but were still too hot for me most nights in the southern mountains.  I have chosen the quilt because of the light weight, the open bottom and the fact it will sleep "just like at home" under the quilt at night.
Therm-a-rest Alpine 35 degree Quilt
So in this corner, I am looking at the Therm-a-rest Alpine. A 35 degree sleeping quilt, with no bottom, no zipper, and low weight.  This seems like what I am looking for down south.  I would rather wear more clothing at night and carry a lighter quilt if I could.  This bag was also rated at 40 degrees by a reviewer here.  The Therm-a-rest Alpine is $250 at Campmor.
In that corner, is the 20 degree GoLite quilt, with more insulation for cool nights in the mountains and higher elevations, and water proofing on the foot and head.  The GoLite quilt is on sale for $199, (usually is $400) a great price!  Check here for a review.
GoLite 20 degree Quilt
I do have a short Ridge Rest pad to sleep on but would like to purchase a Z-Rest pad since I have tried it and I found that I prefer folding it instead of rolling it.
We do camp during the winter here in Florida and in the summer anywhere else.  It can get cold but is usually in the 40's and 50's at night.  Most of my camping experience in the southern Appalachian mountains has been comfortable with 50 degree down to 30 degree nights.  In Colorado it was always colder and I rarely had enough insulation in my sleeping bag to keep warm.  I don't think I"ll be camping in the inter-mountain west any time soon, but you never know.  When I do it will be with a 20 degree quilt.
I have many, many more 'minutia' decisions to make just like this.  It would be interesting to hear your experiences in different temperature-rated sleeping bags and quilts "down south".  Please write in to let me know your preferences and why.  Much more minutia to come...
