Overview
Strapping on this pack puts a hydration reservoir and organized storage on the rider's back. Nylon and polyester fabrics, a ventilated back panel and an overflow pocket for a spare layer round out the design.
The reservoir uses the Quicklink System and a Magnetic Tube Trap to keep the drinking tube close at hand. A removable stability belt adds flexibility in how it is worn. Body modifications were made for a smoother ride and fit.
Who it's for
Day riders on trails who value ventilation and a stable ride will be comfortable here. Longer trips with heavy loads call for more storage than the cargo listed.
Pros and cons
- Overflow pocket for a wet jacket
- Removable stability belt
- Magnetic tube trap
- Ventilated Air Support back panel
- Modest cargo volume
- Reservoir only, no other accessories listed
Performance notes
Air Support Back Panel and lightweight fabrics promote airflow along the spine so the rider stays cooler. The stability belt limits the pack's movement on rough ground, and the tube trap holds the hose in place between sips.
