Ultra-durable dry protection with easy viewing. Save time and energy by swiftly identifying contents in our waterproof Discovery View dry bag. The PurgeAir valve quickly vents trapped air for easy closing and packing, while the oval bottom helps keep the bag from rolling around. Color-coded oval bottom: Color-coding distinguishes between bags; stable shape won’t easily roll around and is easy to store, stack, and pack. Durably constructed: Fully welded seams result in stronger and more durably waterproof construction compared to sewn-and-taped seams. Tight, simple sealing: Updated DrySeal™ roll-top closure makes it easier and more intuitive to achieve an optimal seal. PVC-Free: Materials have a reduced environmental impact over vinyl-coated materials.
