The supremely ventilated, featured and durable Sirrus Series receives a makeover that is more than skin deep for Spring 2017. Now featuring adjustable torso lengths, improved womens specific fit and comfort with updated aesthetics, the Sirrus 50 is the go-to choice for everything from big day hikes to overnight jaunts in the backcountry. When the weather turns, fear not Sirrus keeps your gear and pack protected with an integrated raincover. Smartly organized pocketing keeps all your equipment where you need it, when you need.

AIRSPEED SUSPENSION

Incredibly comfortable and ventilated tensioned mesh backpanel with added adjustability for variations in torso length to provide fine-tuned customization fit for every hiker and backpacker.

SEAMLESS HIPBELT INTERFACE

Users cant feel seams that dont exist, and because there arent any on the Stratos/Sirrus updated hipbelt, hikers can focus on the journey instead of the pack on your back.

INTEGRATED RAINCOVER

Hope for bluebird weather but know youre covered with our integrated and removable raincover that stows in its own pocket when the sun returns.
