Quite possibly the most ingenious camp cup ever created. It's shatterproof, BPA-free stainless steel built for all your drinking, sipping and toasting needs at the cabin, on the trail and around the campfire. Generous 18-oz. capacity swallows a full-sized 12-oz. bottle with room for a proper head. Better yet, there’s a bottle opener and resealer built into the base, so you’ll never have to open a brew with your shoe.
