Not for long runs
- Familiarity: I've used it once or twice and have initial impressions
I bought this bottle for my first ultra. The bottle works well only when it is more than half full. After drinking more than half the bottle's contents, it lacks the stiffness to stay in the holster. Without me noticing, the bottle slipped out of the holster during my race. For that reason, I don't recommend this water bottle.
