Ultra-Light. Ultra-Snug. Zero Distraction.

Built for women who want nothing extra and nothing in the way, the AeroZip delivers a dialed, aerodynamic fit contoured to move seamlessly with the female form. Ultra-light materials, a women’s-specific silhouette, and targeted breathability come together to create a vest that feels fast, secure, and effortlessly comfortable—mile after mile.

ULTRA-LIGHTWEIGHT BY DESIGN
Premium stretch fabrics and a minimalist construction strip away bulk for a barely-there feel. Every material choice is intentional—light, fast, and built to disappear once you’re in motion.

AERODYNAMIC, BODY-CONTOURING FIT
A unique contoured design hugs the body for an ultra-snug, locked-in feel that stays put without compressing or restricting movement. The AeroZip moves with you, eliminating distractions so you can stay fully in your stride.

TARGETED BREATHABILITY & FLEX
Highly breathable, flexible fabrics at the back and sides maximize airflow while maintaining an aerodynamic profile. The result is a vest that stays cool, comfortable, and responsive—even as effort and temperatures rise.

HYDRATE WITH EASE
Includes two 17oz / 500ml NATHAN x HydraPak soft flasks that are oval shaped to contour the body for a more comfortable fit.
