Our new Odor-Proof barrier bag, OPSAK, has all of the features of the aLOKSAK plus a new-generation barrier film that is completely odor-proof. Now you can carry food and toiletries virtually undetected. Great for preventing animal intrusions at the campsite.
"When bear canisters are overkill-but you still want to critter-proof your food against racoons, squirrels, and marmots-get LOKSAK's OPSAK bag. These resealable, washable, polyethylene bags are watertight, airtight, and odorproof, so they prevent animals from sniffing out your edibles and toiletries."
