Weight & Packability

Probably the most difficult function to attain with hard-sided bear canisters is low weight and good packability. The Grubcan Carbon has come nearer than any bear canister we’ve seen. This carbon fiber canister weighs simply 1 pound 13.8 ounces, a fraction of the burden of most rivals, which regularly exceed three kilos.

The Grubhub is straightforward to pack, whether or not on the inside or exterior of your backpack. Its lengthy and skinny design (13.4” tall and 23” round) simply slides vertically into any pack enclosure, however like most bear canisters, will solely match horizontally contained in the widest packs. The wavy outer shell offers a helpful ledge to grip together with your fingers in addition to a spot to safe a strap when packing on the skin.

Ease of Use

The Grubcan hits that good center floor of being a no brainer to open for people however an absolute mind buster for bears. The lid has a multi key-lock design with three notched rotating discs that should align completely for the lid to raise off. As soon as aligned, the lid lifts straight off simply—no buttons or threads wanted. No stress is required, and the discs are simple to show even with chilly palms. Apparently, the lid is definitely extra finicky to place again on than to take off, because the discs can generally shift on their very own when the lid is off.

Our predominant criticism with the Grubcan is its slender opening, which makes it considerably tough to pack bigger meals objects or attain for issues which have sunk to the underside. The canister can also be fully opaque, so that you typically should dump all its contents on the bottom to seek out what you’re searching for. Moreover, in case you like utilizing your bear canister as a stool, you would possibly need to think about a unique possibility. The marginally rounded backside and tall peak of the Grubcan make it simple to tip over simply.

Safety

The Grubcan Carbon retains up with the very best in stopping bears from getting in. The canister is created from carbon fiber and Kevlar, making it extremely light-weight and sturdy. The non-see-through design provides an additional layer of safety.

Though the lid comes off very simply when unlocked, a bear must get wildly fortunate to align the keyed discs. We’re not saying it couldn’t occur, however we consider the locking mechanism on the Grubhub is as safe as every other toolless lid design. Lastly, the slippery plastic shell is tough for a bear to select up and carry away with its bear palms.

As a result of Grubcan is a smaller firm, it’s much less more likely to be included on the strict approval record for sure public areas the place curious bears pose an enormous drawback.

Capability

The Grubcan Carbon is offered in two sizes – the 6.6L and 4.6L – each of which appear small for what Grubcan claims they’ll maintain. The 6.6L is marketed to hold a formidable six days of meals for one particular person. The secret is to make use of the “repacking methodology,” which includes eradicating your meals from cumbersome producer packaging (similar to cardboard bins, arduous plastic containers, and normal freeze-dried meals packaging) and repacking it into plastic sandwich baggage. Whereas this frees up lots of area within the canister, it undoubtedly provides an additional step to your planning course of.

With out repacking, the Grubcan 6.6 comfortably holds about 4 to 5 days of meals for one particular person. For comparability, we managed to suit 12 dehydrated Good-to-Go meals right into a single 6.6L canister. That gives breakfast and dinner for six days, with no area left for lunch or snacks.

No matter your packing methodology, the slender opening and wavy canister partitions make packing and unpacking a bit extra of a problem than wide-mouth canisters.
