Description

Seriously, soft flasks are the way to go. The Osprey Hydraulics 250ml soft flask is made by Hydropak and is obviously useful to trail runners for replacing or creating more capacity to their vests. But don't limit it to running. Hikers and climbers also have a super light and compact flask option with it. When it's done, it folds up small, pop it into your pant pocket or in your bag and bring it out at the next water source.
