Theyre impenetrable from the outside, with dual-stage lockable latches and a Dri-Loc seal that create a watertight, dust-proof shield. Plus, this AW2 Double Rifle case is travel-friendly, with a pressure release valve to equalize pressure through temperature or altitude changes and wheels to make transportation easy.
