Made of ultra-durable materials, our versatile and waterproof Discovery(TM) Dry Bag features welded construction for lasting performance, plus an updated closure that makes it easy to achieve a tight seal for excellent protection against water, from day floats, overnight kayak trips, or overland expeditions. The Discovery is available in 5L, 10L, 20L, 30L & 50L. FEATURES - -Built for the journey: Made of rugged, flexible, and fully waterproof materials designed to withstand frequent and demanding use. -Light-colored interior: Significantly eases identification of contents within.* -Oval bottom: Stable shape won&';t easily roll around; it&';s also 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(TM) 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. *Note: The light-colored interiors are achieved by using materials with non-dyed white threads that have a clear interior coating and a solid-colored exterior coating. The plaid bags use materials with dyed threads and clear coatings inside and out-they do not have as light of an interior as a solid-colored bag, though still maintain some translucence.
