TORSO SIZE - Many Osprey packs are available in multiple sizes to fit a range of torso lengths. To determine your torso measurement, please see diagram below. 


*NOTE: This measurement starts at the iliac crest, which is the top of your hipbone on the side of your body that acts like a shelf. From this point, measure to the C7 vertebra, the knobby bone at the base of your neck when you put your head down. Reference the torso length below to match the correct pack size.

WOMEN'S SPECIFIC - True function and comfort along with style. Osprey have over 20 years of experience designing women's packs

Very supportive and incredibly breathable, the Osprey Sirrus 36L is the perfect women's hiking daypack for long, hot days on trail. With a spacious and supportive women's specific design, the Sirrus is also very popular as a day bag on supported tours around the Three Capes or El Camino.

The supremely ventilated, featured and durable Sirrus received a makeover that is more than skin deep. Now featuring adjustable torso lengths, improved women's specific fit and comfort with updated aesthetics, the Sirrus 36 is the go-to choice for everything from short day hikes to lightweight overnights in the backcountry no matter how far, or near. When the weather turns, fear not - Sirrus keeps your gear and pack protected with an integrated raincover. Smartly organised pocketing keeps all your equipment where you need it, when you need.

The women's specific fit you trust Osprey for, this technically sound top-loader with an incredible feature set and ventilation will take you through the desert, swamps and rainforest without beating an eye whether on a big day hike or svelte overnight trips. Just because the Sirrus has a smaller literage doesn't mean the frame should be any less supportive, the Sirrus will keep you on the trail longer with its efficient load-bearing harness that places the weight over the hips. 



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.


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.


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.
