Celebrate your adventure with a swig from the GSI Outdoors® Boulder 10 Flask. The copolyester resin construction stands up to bumpy rides, drops, and dings, while the silicone bumper makes handling it easy and secure. A wide mouth means this camp flask is easy to fill at home, plus it makes it easy to pour and drink from, as well. A hinged silicone cap is easy to grip, even with cold fingers, and makes the lid virtually impossible to misplace. Graduation marks molded into the flask make it easy to see how much liquid is left. The GSI Outdoors Boulder 10 Flask boasts a BPA-free design. Capacity: 10 oz. 6.4"H x 3.2"W x 1.4"D. Weight: 4.1 oz. Manufacturer model #: 79347.
