GREGORY Avos 10 Hydration Pack Running Trail Hiking EUC!

The Avos 10 is perfect for quick blasts after work before sundown. The Shift RS suspension with EVAP moisture wicking backpanel provides incredible ventilation in all conditions and helps conserve valuable energy on the trail. 3D Hydro Reservoir included. I LOVE this backpack, but we just don't use it. Got it at the beginning of the summer, used once on a hike. Reservoir included - never used.
