SEA TO SUMMIT BIG RIVER DRY BAGThe Big River Dry Bags are a durable, strong and abrasion resistant option that uses a 420D nylon fabric with a TPU lamination. If your idea of outdoor recreation involves rugged water sports like kayaking, canoeing, rafting or motorcycle touring, they are the perfect storage bags to keep your gear dry. A white interior laminate affords greater visibility, and hypalon lash loops allow secure stacking or attachment to watercraft, motorcycles and other equipment. The hypalon roll-top closure doesn't wick water, and the Field Repair Buckles can be replaced in seconds with just a Philips screwdriver.FEATURESTPU laminated fabric with 10,000 mm hydrostatic headSuper strong and abrasion-resistant 420D Nylon fabricWaterproof, double-stitched, reinforced, tape sealed seamsWaterproof hypalon roll-top closure does not wick moistureOval base resists rolling - stays where you put itFeatures the patent-pending, 3/4 inch (15mm) Field Repair Buckle with stainless steel pinsTECH SPECS3 liter: a day's worth of snacks, keys and wallet5 liter: some extra layers or a couple days' worth of food8 liter: a layer and a meal or so worth of food13 liter: clothes for a paddle or overland trip, use as a critter/bear bag for food for 1-2 people20 liter: a larger tent and footprint, general gear for a paddle trip35 liter: general outdoor gear (to attach to a motorcycle rack or in a river raft)65 liter: general paddle or overland gear for a larger group
