GSI Outdoors Boulder Flask 16 fl. oz. Green

• Tough and shatter-resistant, the Boulder Flask can stand up to nearly any outdoor adventure; Thermoplastic resin body keeps your drink of choice intact.
• Wide mouth opening makes for easy filling, pouring and drinking; Molded graduation marks help you quickly measure or see what’s left while you’re on the trail.
• See-through design for a fun and novel drinking experience; Hinged top with grippy silicone bumper makes for easier opening, helps prevent leaks and ensures you won’t lose the cap.
• Weighing only 4 ounces empty, the Boulder Flask won’t weigh you down even after you fill it.
• This BPA-free flask is durable, safe to drink from, and doesn’t have any foul or “off” aftertaste.

Our passion is great food in the great outdoors. We adapt the comforts of home for the rigors of your adventures, whether you’re summiting a mountain or setting up on the sidelines of a soccer game. We believe food brings us together, sustains our explorations, and, mysteriously, always tastes better when cooked and eaten outside.
