Nathan | AeroZip 1 Liter Hydration Race Vest | Unisex | Electric Blue/Reflective Silver

The Nathan AeroZip Hydration Vest is an ultra-lightweight running vest designed for runners who want streamlined hydration and a distraction-free fit. Built with minimalist construction and premium stretch fabrics, this performance hydration vest delivers a barely-there feel while keeping essential hydration secure during training and race day.

Engineered with a contoured, body-hugging design, the AeroZip creates an aerodynamic fit that moves naturally with your stride. The snug, locked-in silhouette stays stable without restricting movement, helping eliminate bounce and distractions mile after mile.

Highly breathable, flexible fabrics along the back and sides improve airflow and temperature regulation while maintaining a sleek, performance-ready profile. The result is a hydration vest that remains cool, comfortable, and responsive even during high-effort runs.

For easy hydration on the move, the vest includes two 17 oz (500 ml) HydraPak soft flasks designed to contour comfortably to the body. Lightweight, secure, and race-ready, the AeroZip Hydration Vest is ideal for long runs, trail adventures, and endurance racing.
