GSI Outdoors says:
Your favorite beverage can now go anywhere in the Boulder Flask. Includes graduations for measuring and can take any fall with the sleek bumper flask. The Boulder 10 Flask holds 10 fl oz, has a shatter-resistant body with bumper, graduations, and a hinged silicone cap making it impossible to misplace.
Our Verdict
GSI Outdoors' Boulder Flask 10 fl oz 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.
This updated version has the benefit of using BPA Free plastic. 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 BG for staff to get one!
