Works as advertised.
It works well with the Black Diamond Distance 8 that I have. No major issues after a few uses. I'd buy them again over some of the other varieties out there.
Great...not perfect
Great...not perfect. The cap on this is small. Meaning it's harder to fill with liquid or supplements. I have several other versions with a much wider opening.
Perfect for ditching the vest
This flask fit incredibly well into the pocket of my Janji Trail Tights and Half Tights. Made it easy to ditch a vest for long runs with intervals.
