The Sea to Summit Ultra-Sil® Dry Sacks are a lightweight tool for keeping essential items dry during trekking excursions, camping trips and backcountry backpacking adventures. These sacks are more than 50% lighter than Sea to Summit’s super popular Dry Sacks. They're constructed with Ultra-Sil™ nylon, which is a Siliconized Cordura that’s one of the lightest, durable, and most waterproof nylon fabrics available. Non-wicking Hypalon® roll top closures with stiffeners help improve their seal. Sea to Summit finished these sacks with easy-packing slippery finishes, which help them slide in-and-out of backpacks.
