500mL Locking Cap Flask

Road Running -- locking cap

I run almost exclusively on roads and do marathons regularly. works perfectly. Easy to drink from in any position (ie above or below mouth). Fits nicely into the belt. Doesnt leak when locked. Can leak some if not locked. Lock mechanism is easy to manipulate while running. the soft design prevents any rubbing that I have had in the past with hard bottles.

love these!

definitely my new favorite flasks for training and racing :)

Simple & effective.

Super simple great locking flask with a wide lid. 10/10
