Osprey Duro 6 Running Vest

Escarpment Verified: The Escarpment Workhorse (10K to 50K)

If you are planning to spend your Saturday chewing up technical limestone on the Bruce Trail, the 6-liter Duro is your ultimate wingman.

This is the sweet spot of hydration vests—big enough to hold mandatory race gear and extra layers for unpredictable Ontario weather, but streamlined enough that it won't feel like a heavy parachute. Engineered with a refined, bounce-free fit, it hugs your torso like a second skin.

It comes fully equipped with two 500ml Wing Stay soft flasks and features easily accessible stash pockets for your phone, keys, and an arsenal of gels. It’s the rugged, daily driver for mid-to-long distance trail runners.
