    Hike on Cloud Nine.

    The second you put on the Osprey Women's Sirrus 24 Backpack and feel its mesh AirSpeed back panel successfully transfer the load to your legs, you get overwhelmingly excited, if not giddy for the big hike ahead. The AirSpeed suspension system combines the rigidity of aluminum stays with a tensioned mesh back panel for effective load transfer and cross ventilation, while the Women-specific Spacer Mesh hip-belt and shoulder straps ensure your load rests where it should for max efficiency and pain-free hiking.

    Its ErgoPull waistbelt closure makes cinching down the belt easy, and hipbelt pockets hold your camera, shades, or quick snacks so you keep spirits high. And if rain starts to fall on your adventure, deploy the integrated rain cover to keep your gear dry as a bone. A Stow-on-the-Go feature on the left side lets you holster your trekking poles or ice axe for hands-free walking, and the compression straps let you adjust the pack's volume to fit different load sizes.

    • Easily organizable, lightweight, and supportive daypack
    • Breathable, mesh backpanel with aluminum stays transfers loads
    • Mesh, padded shoulder straps stabilize the load comfortably
    • Integrated rain cover helps keep your gear dry
    • Ice axe and trekking pole attachments free up your hands

    Awesome for travel.

    • Familiarity: I've used it several times

    I used this pack as a carry on, it's the perfect size. The pack is light weight and has plenty pockets. I especially liked the compression straps! It's perfect for hikes and great for traveling.

    No worries if you spilled juice in bag.

    • Familiarity: I've put it through the wringer

    I use this bag mainly for winter hikes because I tend to carry more things.
    I have the tendency to bang my bag into rocks when I hike and there's no rips (my other bags have already shown sign of ware and tear.
    It really is water proof, from inside and out. I have used this in rain and everything inside was kept dry. I had a leak from my juice bottle that was already in my bag. It didn't steep through the layers and out my bag, it just collected into a puddle in my bag. Which I prefer because it was easier to clean. If it had steep through the layers, I would have a much harder time getting rid of the smell and stickiness.
    It's really comfortable and sits on my hips. I really like the two pockets (1 on each side) on hip strap. Great for storing phone and whatever else you need easy access to.

    Best day pack hands down!

    • Familiarity: I've used it once or twice and have initial impressions

    I used this pack on several day hikes in the Colorado Rockies, and I couldn't be happier with it! Osprey packs in general are terrific with their convenient organization pockets and comfortable waist and shoulder straps, suspension, and back panel. This pack in particular is no exception. At 24L, it's the perfect pack for day hikes and allows for a little extra gear to come with you. I used the ice axe loop, which was no hassle to figure out, and there is a rain cover packed into the bottom for rainy days. I was able to carry the axe, a jacket (or two), crampons, three liters of water, snacks, and an extra pair of shoes and pants, and I wasn't even packed to the brim on this pack. The fit is extremely comfortable, and it almost didn't even feel like I was wearing a pack with how lightweight it is and how well it stays put. The storage pockets on the sides of the hips are convenient and easy to use, and I was able to fit a few snacks, chapstick, and my phone in there.

    I'm 5'5" around 145 pounds with a muscular and curvy build and long-ish torso and went with size medium, which fit perfectly. While I didn't use this for backpacking, I would definitely buy the larger version to allow for sleeping bag storage and a few additional items. I HIGHLY recommend this pack for the adventurous day hiker!

    Best day pack hands down!

    Perfect Technical Daypack

    • Familiarity: I've used it several times

    I got this as a gift for my sister and this is what she has to say:

    "This is the perfect daypack for any hike. This bag has plenty of room to fit a 3L bladder along with extra layers of clothing and food and it has various pockets for storing smaller items. I can even access the front vertical zip pocket with the pack on, which is very convenient to be able to grab things like sunscreen or a snack while hiking and not having to take the pack off your back. All of the straps make for easy adjustments for the perfect fit that you barely even notice the pack is on. The hip pockets are even big enough to fit my phone and keys into. The only flaw I have noticed is the opening for the hydration tube is very small and tight that it can be a little tricky to get the bite valve through. Overall I love my Sirrus pack and all of its technical features."

    I have been told to rate this five golden stars. We love Osprey so much! Their products continue to satisfy.
