I purchased this looking for an additional bladder type bottle to take on rides and while this was workable, it will not be a regular part of my rotation. The flask feels a little unwieldy unfortunately to finagle whilst on the bike. This was not marketed as such to me, so i won�t fault it, but at the same time, taking it with me on a jog was not impressive either. This really feels like a niche product for hikes where you need something that can squeeze into anything and has no noticeable affect on weight.
