GSI Outdoors Boulder 6 Flask

The last thing you want is to get into the middle of the woods, drop your flask, have it shatter, then watch as a slug take a bath in your favorite drink as it disappears into the dirt, slowly. The GSI Outdoors Boulder 6 Flask will keep that from happening, thanks to a shatter-resistant copolyester construction and a grippy silicone bumper to keep it in your hands in the first place.
