I am a hiker with over 10 years of high-altitude trekking experience. Among all the Osprey daily backpacks I’ve used, this one has the best suspension system design — especially the back ventilation, which keeps your back cool even in hot summer weather. The backpack has been used lightly to moderately and is in clean, good condition. There is a small yellow mark on the bottom of the pack, and one zipper pull has been replaced with a substitute cord. These minor flaws do not affect its functionality. I hope this pack becomes a great companion for your summer hikes. I used to have a purple one as the picture attached. Features: This Osprey Sirrus 24 Women's Backpack in Teal/Grey is perfect for backpacking, hiking, and camping. It has a capacity of 24 L and features adjustable sizes, external pockets, and a zip closure. There’s compression straps on the top for attaching a rope, a bungee cord ice-ax holder, and a stow-on-the-go bungee cord system to tuck your trekking poles into, if you need your hands free for scrambling or clearing away brush. The Osprey Sirrus 24 is well-designed for all kinds of outdoorsy ladies in mind—hikers, mountaineers, climbers. Whether you're a seasoned backpacker or just starting out, the Osprey Sirrus 24 Women's Backpack is a great choice.
