Keep your valuables dry and protected from the elements with LOKSAK® bags. Re-sealable element-proof storage bags that feature a hermetic seal. That means absolutely no water, air, dust or humidity permeates the closure. They are designed for a wide range of applications and environments. The transparent bags are flexible and puncture resistant. This is the same LOKSAK® bag used in the Waterproof SPIbelt™. Three per pack.
