Why We Like the Osprey Dyna 1.5L Backpack

Equipped with its own reservoir, the Dyna 1.5L Backpack delivers a minimalist fit without compromising the hydration and storage space needed for our long trail or road runs. A combination of zippered and drop-in pockets keep snacks, gels, and valuables organized, while back bungee storage stashes extra layers or hats.

I've used it several times

This pack is so comfortable that on mile eight of a run, I startled because I thought I wasn’t wearing it anymore. The clips on the front are difficult to refasten while you’re running.
