The VELLYN Running Vest system is designed to remove distraction and keep you moving efficiently, whether you're training early, running late, or pushing distance. Lightweight, adjustable, and built to sit close to the body, it delivers a secure, bounce-free fit that moves naturally with you. Designed as a unisex, one-size system, it comfortably adapts to chest sizes from 28" - 46" ensuring a close, stable fit across a wide range of runners. Every detail is engineered to carry only what you need - without adding unnecessary weight. Paired with a 300ml collapsible soft flask, hydration stays accessible without bulk, compressing as you drink so it never gets in your way. Integrated reflective detailing and two rechargeable clip-on lights keep you visible in low-light conditions, giving you confidence to run whenever you choose. With six secure storage zones - including a waterproof pocket and dedicated phone holder - you can carry your essentials without breaking stride. Because when you’re running, performance isn’t just about speed - it’s about eliminating everything that slows you down.
