UltraX Lightweight Running Vest with 500ml Soft Flask
The UltraX Lightweight Running Vest is designed to sit close to the body with minimal bounce, so you can focus on your run instead of adjusting your gear. Whether you’re heading out for a short session or pushing further on longer runs, it keeps hydration and essentials secure, accessible, and evenly distributed.
This running vest includes a 500ml soft flask that sits firmly in place, allowing you to hydrate without breaking stride. The streamlined fit reduces movement while running, helping prevent chafing and discomfort even over longer distances.
A secure, water-resistant phone pocket protects your device from sweat and rain, while keeping it easy to reach. A discreet earphone pocket allows you to store AirPods or earbuds without loose movement or rattling. Every pocket is designed with purpose, so nothing feels bulky or unnecessary.
The adjustable strap system allows you to fine-tune the fit to your body, reducing bounce and improving stability. Breathable mesh panels promote airflow to help regulate temperature during harder efforts, while the lightweight construction ensures the vest feels barely there once you’re moving.
Designed with a unisex fit and tested across different run types, the UltraX running vest is ideal for runners who want a clean, secure solution for carrying hydration, phone, and small essentials without overcomplication.
