The odor-proof ziplocking bag
©Outdoor Adventure Canada
We often hit the trail
or waterways in black bear country where we have to hang our foods.
This is quite different than having to use an approved canister or
Ursak in grizzly country. Food hanging, if done properly, will keep
all of the critters out of your food. That said, I still try to reduce
A few years ago I started using a product
called the OPSAK from a company called LOKSAK (formerly Watchful Eye
Designs). These ziplocking bags are great for people who dry their
own foods for reheating on the trail. The bags are certified waterproof
and will handle temperatures as low as -40°C (-40°F) and as
high as 76°C (170°F).
The bags are not rated for being placed
into boiling water but the manufacturer indicates that you can safely
add boiling water to the bag. This is great for rehydrating foods
and they are more durable than ziplocking freezer bags which often
warp with the addition of boiling liquids (potentially leaching chemicals
into the food). The OPSAKs are FDA approved.
The OPSAKs are fully recyclable. While
they are more a bit more costly than ziplocking freezer bags I can
confidently say that they last 10 to 15 times longer.
For general waterproof storage without
the odor proof barrier you might also want to look at the aLOKSAK.
