Bare Boxer Contender: A Small 2-3 Day Bear Canister

The Bare Boxer Contender (Model 101) is a small bear canister with a two-to-three day capacity, perfect for the short weekend backpacking trips I take year round. I also own a larger Garcia Bear Canister but it can hold 5-6 days of food and has far more capacity than I need. It’s also an ungainly thing to pack in a smaller volume ultralight backpack and I’d rather not bother with it on shorter trips. Both of these canisters are approved by the IGBC and SIBBG for use in Grizzly and black bear country.

While I am still not required by law to carry a bear canister on weekend trips in New Hampshire, there are some advantages to carrying the smaller sized canister over a normal bear bag or a Ursack.

  1. The Bare Boxer Contender can’t be compromised by a bear or smaller animals like mice. Ever.
  2. Requires no skill to hang or tie knots.
  3. Can be stored on the ground.
  4. More time for hiking. Easy to stash, even after dark.
  5. Fits inside small ultralight backpacks easily.
  6. Easy to clean.


At 275 cubic inches / 4.5 liters, the Bare Boxer Contender (Model 101) is the smallest volume and lightest weight bear canister available today. 275 cubic inches will fit 2 days of food or even 3, if you pack very carefully with as little packaging as possible.

While small, the Bare Boxer Contender is more than adequate for a weekend trip, easy to pack, and barely larger than a large stuff sack. It can also be stored inside or outside you pack easily, provided you have some kind of top pocket that can hold it to the top of your backpack.

Locking Mechanism

The locking mechanism on the Contender is very simple, just three rotating locks with a pin that must be depressed while turning the lock. This is easily done with a small knife or the nail file on a tiny Swiss Army Classic knife. I doubt a bear could get his claw into the narrow slit provided. That’s all there is to it really.

You’re probably wondering why I would consider carrying a bear canister instead of the Ursack (a soft bear resistant Kevlar bag) that I’ve been using for the past 6-7 years. There are a couple of reasons. First, my local US Forest Service Conservation Officers are becoming increasingly vigilant about enforcing backcountry bear storage regulations in the parts of New Hampshire where I do most of my hiking and backpacking. I talk to the rangers regularly, including the rangers in charge of bear enforcement, and none of them have ever heard of a Ursack (nor will they want to be educated when writing a $125 ticket.)

Hopefully, that time won’t come, but the increase in food related bear incidents in New Hampshire suggests otherwise. Regardless, the length and frequency of my overnight trips will not change, hence the need for a lightweight bear resistant canister capable of carrying 2-3 days of food like the Bare Boxer Contender.

  1. I started with the BearVault 450 years ago, then moved to the Bare Boxer Contender. Mine’s 26.7 ounces, so basically 1 2/3 lbs (heavy, but not nearly 3 lbs.).

    I HATED hanging food, it was so tedious and drained energy after a long hike. A lot of times I’m above tree line anyway (first Sierra Nevada, now Rockies). It is SO EASY to use the Contender, it’s so worth the extra weight for me. If I forget something in my food stash, I can get to it in a few steps! No bringing the food down, re-hanging, re-tying, etc. I’ve had to pitch camp in the dark above tree line in marmot and porcupine country; good luck protecting food in that scenario! And, the thing is pretty much waterproof (just set it upside-down, and it will take on hailstorms and snow without getting any water in it at all). Food is much less likely to get crushed, too, because of the hard sides.

    I wish Wild Ideas wasn’t so expensive. Their weight-to-volume ratio is tempting. I might try renting one for a week-long solo trek I’m doing this summer, but to be honest I can fit several days of food into the Contender, so I might not bother. But for me, hands down a canister has made life MUCH easier on the trail.

  2. Excellent table of the options. I almost never hike solo, so I’d probably go for the BV450 to handle a night or two with my wife. But yeah, bear bagging is a huge hassle and not as easy as it looks.

    On our Boy Scout Sierra 50 Miler, we had one unrecoverable bear rope left in a tree for the first three nights. So much for Leave No Trace. Later in the trip, a crew member got whacked in the neck while dislodging a stuck rope with a rock tied to the end. He was shocky all evening and couldn’t turn his head for a couple of days. And that was a very good outcome.

    So yeah, pack a bear canister.

  3. The BV500 is the best value; weight, cost, ease of use, and capacity. You don’t have to fill it all the way up and you can see through it. Go to an REI or similar store and do a side by side comparison.

    • I will never use a bear vault bear canister,,,my experience was almost exactly like someone else’s on a backpacker blog. Went for a four night b/ p trip in Emmigrant Wilderness. First night packed up everything food/fragrance wise for the night but forgot to put lip balm in. I worked for an hour to try to get it open…then my friend tried her Bear Vault to get her heart mess out and hers wouldn’t budge either!!! I threw it against rocks, dunked it in hot water ( got wet inside)…and dint sleep a wink. The next morning we had to turn around and go back to the car…Ruined our whole trip…what trip??? Don’t buy it….you can’t trust it.

      • I cut a piece off an old credit card and use it to put between the tab and stopper of the Bear Vault and it opens very easily.

  4. My UDAP canister has similar locks. I taped a washer about the size of a quarter on the top and bottom of the canister as emergency openers if nothing else was handy.

  5. Why would rangers in the White Mountains not accept the Ursack? The S29 AllWhite is IGBC certified (#3738). For those interested, the IGBC certification list is available here: http://igbconline.org/certified-products-list/

  6. I have owned and used extensively the Bare Boxer Contender with excellent results. It is outstanding for 2-3 day trips (or longer with mid-trip resupply) and fits easily into ultralight packs. I also have the Ursack, several Bear Vaults of both sizes and used to own the Bearikade but sold it ten years ago when SEKI decided to allow the Ursack (big mistake since that was very short lived).

  7. I use Ursack and like the compressibility and light weight. Won’t change unless required by law!

  8. I received a Bare boxer model 101 about a month ago as a gift. I love it!
    I also have a Bear vault that I like, but have had a lot of trouble opening it at altitude. I asked my local REI if any of their stores carry the bare boxer as I’d like to get another one. The sales guy said he has been using one for several years and thought REI would be selling it in the near future.
    I hope so because I don’t like buying anything on line!
