This New Flask Is Perfect for Taking into the Woods

Most who trek into the woods aim to keep their backpacks as light as possible.


Gear innovation within the outdoor space has traditionally been aimed at solving one problem: make things lighter. When you’re walking trails and climbing mountains, what you can carry on your back determines what you bring; ounces are counted, and excess is left behind. There are exceptions to the rule though — to bring a choice beverage is one of them.

GSI’s new Boulder Flask is equipped to hold that extra warmth in a vessel that’s both lightweight and durable. The 10-ounce flask is made with a copolyester body and wrapped in a silicon bumper to mitigate any tumbles on the trail. It’s a construction that’s as durable as, but much lighter than, comparable flasks that are made with metal or other rugged plastics. The copolyester body is also conveniently clear, providing a visual for exactly how many ounces remain inside (which is also perfect for load management of a different sort).
