This set of four aLOKSAK Waterproof Bags from Loksak contains one of each of the following size bags: 3.7 x 7", 4 x 7", 6 x 9", and 8 x 11". The bags are waterproof and airtight protecting your electronics, documents and other items that need shelter from the elements. A double-zipper closure creates a hermetic seal, which prevents any air, dust, or micro-organisms from leaving or entering the bag once it is sealed.

The recyclable and reusable aLOKSAK bags are made from FDA and NSA-approved medical grade polyethylene that is safe for both food and biohazard storage. You can make and receive calls, and use touchscreens from phones or tablets within the bag. They are certified waterproof up to 200', and remain effective from -40° to 140°F.
