Bring your favourite bevy where no one has gone before with the GSI Boulder Flask. Carrying that favourite bevy can be somewhat of a pain, especially when so many of the choices out there are the same shape. Now the flask shape is not a new by any means, but taking it to a new level is what the GSI Boulder flask is all about. The 10 oz. minimal sleek body is made from shatter-resistant eco-friendly co-polyester, and surrounded by a grippy, silicone bumper. Incredibly lightweight, it has a wide mouth ideal for sipping, chugging, pouring and easy filling. The hinged top silicone gripped lid make the GSI Boulder a slim, go anywhere, fall worthy flask fit for any and all adventures alike.
