The supremely ventilated, featured and durable Sirrus Series has received an update. Now featuring adjustable torso lengths, improved women's specific fit and comfort with updated aesthetics, the Sirrus 24 is the go-to choice for those who prefer panel-loading organization on day hikes in wet or hot environments where staying dry and keeping your cool matter most. 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 it.
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.
