NRS Ether Dry Sacks keep your gear dry and protected on your next foray into the wilderness without tacking on a ton of extra weight. Made with a rugged, yet lightweight ripstop fabric, these dry sacks toe the line between heavy-duty durability and ultralight carrying comfort. The envelope shape allows for easy stowing inside packs during backpacking trips, and the watertight StormStrip closure keeps clothing and gear dry when your raft gets flipped on the river. And with a wide variety of sizes to choose from, they can be used to store everything from toiletries and underwear to food supplies and climbing gear.
