Bryant M.wrote a review of Fabric Waterbottle on August 18, 2017
Familiarity: I've used it several times
I mounted this to the underside of the downtube of my hard tail. On the third ride I looked down and it was gone. :( liked the concept and the looks way better than a traditional bottle but it's not doing me any good any more.
I think it would have worked well if I could have mounted it to the topside of the downtube so gravity was pulling down onto the frame rather than away.
I'll try it again if I ever have a bike with mounts on top of the down tube.
