High performance hydration vest made of light materials, minimal seams and unique details. The AeroZip vest is designed specifically for a women's torso and features precision fit – a contoured aerodynamic construction with zipper closure provide an ultra secure feel without sacrificing stability and provides zero restriction.
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.
