Along with being 100% water/air tight like the ALOKSAK, the O.P.SAK (Odor Proof SAK) is also a 100% odour barrier bag. Using the same seal on the OPSAK – no gusset – that is used on the ALOKSAK, but with a different film that is odour proof and FDA approved. You can store food undetected to bears and other pests in your campsite by sealing them in the OPSAK. Also, because the OPSAK is FDA approved, you can use it in food preparation and storage. You can even pour boiling water into the OPSAK because of its extreme heat resistance.

OPSAK resealable bags feature the famous LOKSAK hermetic seal and barrier film to keep body waste and food undetected. Body waste and food can sit side by side in the same backpack, not a great image, but when storage on the run is paramount, OPSAK rules!
