New durable O.P.SAK 100% odor barrier bag lets you store food undetected at the camp site. The only storage bags that hermetically seal when closed. These even fool the rats in Iraq. Tolerant to extreme heat, the O.P.SAK is the leak and moisture-proof storage bag for you. OK to add boiling water to the O.P.SAK to prepare food - the film is FDA approved. SSI (formerly NASDS) certified waterproof to depths exceeding 60 meters.
