BUILT FOR SPEED

Vest-pack fit provides bounce-free stability and purpose-built for incredible comfort so you can focus on FKT’s and PR’s.

HYDRATION INCLUDED

Bottles, reservoirs, and add-on flexibility for short runs, long runs, and everything in between. You decide what you need. Duro/Dyna makes it possible.

EASY GEAR ACCESS

Pockets up front for quick access to fuel and soft flasks, trekking pole storage when you need to use your hands as much as your feet to move forward, and room for rain gear and extra layers.
