The GSI Boulder Flask is a ruggedly designed hip flask that is purposefully built to handle extreme conditions and expansive adventures. The co-polymer construction gives the flash a lightweight feel, but does not compromise durability or sustainability. The material makes up the bulk of the flask's construction and ensures that the carrier is completely shatterproof and impervious to damaging bumps or scrapes. The GSI Boulder Flask is completely clear to ensure users never go thirsty or unexpectedly find their flask empty.

Surrounding the co-polymer body is a silicone bumper that gives the flask a slip-proof grip and doubles up the durability of the flask. A wide-mouth spout makes filling and drinking a breeze and an easy-to-open cap stays attached to the silicone bumper.

The GSI Boulder Flask measures in at 3.7" x 1.1'' x 6.5'' and is capable of holding 10 fl. oz.
