GSI Outdoor Flask

GSI Outdoor Flask


Lighter than most metal flasks, the GSI Outdoors Boulder Flask has another advantage over its competitors: you can see when it's running low. Its body is made from transparent, shatter-resistant copolyester resin, with a grippy silicone bumper running around the outside for protection against bumps and drops. The wide mouth makes filling and pouring a cinch, and the top is hinged so it won't get misplaced.

Height: 6.5" / Width: 3.7" / Depth: 1.1" / Weight: 4.1 oz. / Capacity: 10 oz.
