Top to bottom, this is our lowest profile flask. It slips right into the snuggest run belts and leanest vest pockets. The new 28mm locking cap easily opens and closes with a touch of a thumb, preventing leaks and drips while in motion. Made for minimal distraction, the innovative pinch-welded bottom gives it a tapered profile and the low-diameter cap makes it comfortable to carry — no pokes or irritation.

John H. ★★★★★

The locking cap is a total game changer during runs—I can open it with one hand while moving without fumbling. This 500ml flask gives me just enough hydration without weighing me down, and it truly disappears into my tight belt pocket.

Madison ★★★★★

This thing disappears into my vest pocket, no bounce at all on a 10-miler. The cap locks down tight with just a thumb flick, so I never worry about leaks in my belt.

Madison U. ★★★★★

The 28mm locking cap is genuinely one-handed, which I didn't expect to care about until I was mid-climb with gloves on. It also sits flat enough that my vest pocket doesn't bulge at all.
