A no-nonsense, good sized flask that is lightweight, durable and easy to use. No matter what you intend to fill in with, water, milk or something stronger and more interesting this is a great flask for taking with you.
GSI Outdoors says:
Your favorite beverage can now go anywhere and take any fall with the sleek bumper flask. The Boulder Flask holds 10 fl. oz., has a shatter-resistant body with bumper, and a hinged silicone cap making it impossible to misplace.
GSI Outdoors' Boulder Flask holds up to 295ml of your favourite tipple. A simple, clean design with see-through sides (so you can see how much you have left) and a silicon grip around the sides to add stability and durability. The same rubber is used on the screw top to add extra grip making it easy to use. The use of shatter resistant plastic mean this is a pretty rugged flask and has been a firm favourite for overnight camping trips for a while now.
The lightweight design of this flask it topped off by the intelligent use and placement of the silicon bumper. You know it's a good item when there is a queue here at UOG for staff to get one!
