    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
    • Compression straps cinch down bulky loads
    • Osprey packs is based out of Cortez, CO

    Great for our day trip!

    • Familiarity: I've used it several times

    My wife and I hiked a few canyons in Zion National Park and this was a great pack to have. It fit a harness, wet suit, dry bag and clothes along with lunch. I would definitely recommend this pack.

    Great pack!

    • Familiarity: I've used it several times

    LOVE this pack! I am a huge fan of women's specific packs; I have a shorter torso and men's packs are often too long. This size is perfect for day hiking and can fit my binoculars, lunch, water bottle, first aid kit, and more. The hip belts are solid and supportive, and I can't live without hip pockets. My phone barely fits in the hip pocket which is a bummer, but I love using them for chapstick, treats, and trash that I pick up while hiking. I was looking for a pack that could securely fit my water bottles on the outside- but a 32 oz classic Nalgene bottle is a bit tight and feels sketchy on the side. A smaller or skinnier bottle would fit better. Other than that, I can tell this is a quality pack and I'll be using it for years to come.

    Very comfy day pack!!

      This backpack is an incredible option if you're on the lookout for a great day pack. The design of it distributes the weight very well so it doesn't feel so heavy. I also love the breathable, mesh backpanel since I was wearing it down in the desert and it was hot! The backpanel allowed for plenty of airflow so my back didn't get sweaty which is always a plus.

      It also has great storage. Plenty of well-placed pockets for everything you could need. We had a good amount of snacks, water, a water filter, dog treats, and a couple of layers and we still had room in there. The side water bottle pockets are stretchy and big enough to hold Nalgenes which is great. The hip belt pockets are also so convenient for snacks so you can eat as your hiking! Or anything else you want easy access to.

      Overall, very happy with this pack and made my day hikes even more enjoyable than before!

      Present For Mom

      • Familiarity: I gave it as a gift but have feedback to share

      Last year I bought my Mom a jacket the same color. I was excited to see this backpack and bought it right away for my Mom. She opened it up Christmas morning and was stoked. Great day pack size. She will enjoy little the trails and matching. Enjoy mom!

      Great Design!

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

      This pack seems well-made, great pockets, just enough padding to be comfortable but not an overkill level. Has perfect hip pockets and water bottle holder which are requirements for any pack of mine (phone holder, snack holder, and easy drink access).

      Beautiful Pack!

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

      I bought this pack after my previous pack was stolen out of my car at a trailhead. I love the many pockets, adjustable straps, padded hip belt, floating frame, and built-in space for a water system. Although I purchased this as pack for day hikes, I probably should have gotten the next size up so that there would be more storage for clothing and extra food during winter hikes. Perfect for summer day hikes, but not quite large enough for winter. Beautiful color and great pack!

      Love my Osprey!

      • Familiarity: I've put it through the wringer

      By far the best backpack I have ever owned. No matter how much weight I have packed into this bag it always feels weightless on my back. Plenty of room for everything I need for a day hike~ lots of assorted sized pockets & compartments, but nothing ever gets lost at the bottom; supports keep the pack off you back & distributes the weight evenly. I hike often & not one hike has gone by where someone does not ask me about this backpack & where I got it~ some have even taken a picture of it! If you are on the fence~ just get it,, It will not disappoint!

      My sister used this for 500mi in spain!

        This item was as big as you need for the camino de santiago. The build in rain fly came in super useful for utilizing the space. Personally my thoughts were that we didn't bring enough stuff, but after the first week we dropped about half of the weight and this pack was only half full!.

        Buen Camino!!

        Cannot recommend enough!

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

        I live near Osprey world headquarters, but I swear the local pride does not color my assessment of this pack. I have owned/used a handful of Ospreys and this one sits at the top of the pack. It is the perfect size for day hikes. I can fit my camel bak, a few layers, a hat, some snacks, and other small items, all with room to spare!

        A couple of nalgenes fit snugly in the mesh side pockets, too. I find the hip belt pockets are actually functional - I can fit my regular-sized iPhone, keys, and chapstick comfortably into a single pocket and it is easy enough to access. The pack is incredibly adjustable to fit your frame; it even has straps just above the shoulders that you can tighten down without taking the pack off; this helps snug things up when your load starts to lighten throughout the day. As a bonus, it comes with a nice rain cover in its own compartment that can be accessed quickly and easily.

        The suspension system is AMAZING. I swear it makes this pack feel next to weightless. The next time I invest in a larger pack (60L+), I am definitely going to seek out this suspension. I do not have it on my 46L pack which is still very comfortable, but the suspension on this 24L might have ruined me for regular packs.

        A++ for ergonomic fit, nice storage, and for making a women's pack in non-"girly" or super light (re: filth-attracting) colors - my historical and singular beef with Osprey packs. I got the black. The pictures show the details as a sort of peachy color but it is def pretty orange, which I like.

        Heaven for your back

        • Familiarity: I gave it as a gift but have feedback to share

        This is the most comfortable backpack I've ever put on. I bought it for my mother-in-law for Christmas, and I am very tempted to buy one for myself. My sister-in-law who has back problems tried it on and ordered one for herself right away. I am 4'11' and backpacks often hang right on my butt instead of putting the weight on my hips. I was surprised that this one size fit me so well! I myself own an OSPREY Women’s Kyte 36 XS/S backpack, and it fits me not as great as this one- size backpack.

        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.

        Stupid question and I’m sure the answer is yes, but is the Sirrus Pack compatible for a bladder system? I noticed it only has one “pocket”. Is there a bladder hanger in it?

        Does this pack have a designated spot for a hydration bladder / place to thread the tube through? Thanks!

        Is the Sirrus 24 able to attach to larger Osprey packs, like the Aether/Ariel series? I'm planning to get a day pack and a larger pack, and am curious about the compatibility. This would be used for treks when I would want to bring both a large pack for through hiking and a day pack for out and backs.

        Thanks for reaching out, Catherine!

        Negative, you could probably find a way to attach this pack to a larger one but it is not meant to be integrated. For that feature, check out the Daylite series. Both the Daylite and Daylite Plus will integrate with larger Osprey packs.
