GSI Boulder 16 Flask
The GSI Boulder 16 is a durable hip flask designed for backcountry adventures. It combines a shatter-resistant copolyester body with a protective silicone bumper to withstand rough treatment in harsh environments. Built-in graduations let you measure portions precisely, while the hinged silicone cap stays tethered so it won't get lost on the trail. The low profile design fits easily into clothing and bacpack pockets.
