Along with being 100% water/airtight, the OPSAK (Odor Proof barrier bag) is also 100% odor proof. Loksak uses a film that contains a barrier so odors dont permeate from the OPSAK. All Loksak bags are FDA approved. You can store food undetected to bears and other pests in your campsite by sealing them in the OPSAK. You can even pour boiling water into the OPSAK because of its extreme heat resistance, however, you cannot sit the bag in boiling water or a microwave.
