The Nathan TrailMix Women's Running Vest is a high capacity hydration pack designed to move with you on long runs, day hikes, and backcountry routes. With a 12 liter capacity and an included 2 liter bladder, you can stay hydrated and carry essentials within easy reach. The vest is tailored to the female form, with adjustable side straps that dial in a comfortable, secure fit.

Smart design for comfort and steadiness

Internal compression tightens the load against your back, reducing bounce as you pick up pace. Mesh fabric wicks sweat and dries quickly, while soft touch binding minimizes chafing for all-day wear.

• Adjustable side straps personalize fit, helping the pack stay in place
