Built for runners who want hands-free hydration with built-in low-light visibility, the HyperNight QuickStart 2.0 4L Hydration Pack pairs our minimalist QuickStart design with an expansive reflective geometric print that boosts visibility in early-morning and evening conditions. Ideal for road and trail runners of all levels training in low-light hours.

Moisture-wicking stretch-woven fabric, chafe-free binding, and breathable mesh shoulder straps round out the comfort kit.
