Ultra-durable, multipurpose dry protection. 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. 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 10L, 20L, 30L & 50L. 5 LTR 10 LTR 20 LTR 30 LTR 50 LTR Weight 6.2 oz (175 g) 9.7 oz (275 g) 13.8 oz (390 g) 1 lb 1 oz (500 g) 1 lb 7 oz (645 g) Dimensions 4 x 7 x 10 in (11 x 17 x 25 cm) 5 x 8.5 x 14.5 in (13 x 21.5 x 36 cm) 6 x 10 x 21 in (15 x 25 x 53 cm) 7 x 12 x 22 in (18 x 30 x 55 cm) 9.5 x 15.5 x 22 in (24 x 39 x 55 cm) Volume 305 cu. in (5 liters) 620 cu. in (10 liters) 1220 cu. in (20 liters) 1831 cu. in (30 liters) 3051 cu. in (50 liters) Material(s) PVC-Free 300D 18 oz polyurethane-coated polyester PVC-Free 300D 18 oz polyurethane-coated polyester PVC-Free 300D 18 oz polyurethane-coated polyester PVC-Free 300D 18 oz polyurethane-coated polyester PVC-Free 300D 18 oz polyurethane-coated polyester Country of Origin Made in USA of US and Imported Materials Made in USA of US and Imported Materials Made in USA of US and Imported Materials Made in USA of US and Imported Materials Made in USA of US and Imported Materials
