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 women's 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 can't feel seams that don't exist, and because there aren't 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 you're covered with our integrated and removable raincover that stows in its own pocket when the sun returns.
