Hydraulics Soft Flask
Add-on or aid replacement for vest-pack harness pockets or a handheld accommodates the 360mL or 500mL flask.
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.
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.
