A women-specific day pack that incorporates ample cooling and an effective suspension system.

The moment 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. Thanks to this pack's tapered shoulder harness, shorter torso length, and narrow waist belt, you no longer associate ten-mile hikes with pain. And since the Sirrus 24 comes in two different sizes, you can find one that's just right for you.

  • AirSpeed suspension combines the rigidity of aluminum stays with a tensioned mesh back panel for effective load transfer and cross ventilation
  • Women-specific Spacermesh hip-belt and shoulder straps ensure your load rests where it should for max efficiency and pain-free hiking
  • Front panel access means you can easily reach everything in your pack's main compartment without unpacking
  • Hip-belt pockets hold your camera, shades, or quick snacks so you can stay in the groove
  • ErgoPull waistbelt closure makes cinching down the belt easy
  • Stow-on-the-Go feature on the left side lets you holster your trekking poles as you walk
  • As soon as the rain starts to fall, deploy the built-in rain cover and keep your load dry
  • Compression straps let you adjust the pack's volume to fit different load sizes

Great Pack

  • Familiarity: I've used it several times

Bought this as a gift and she loves it. It doesn't feel bulky but has quite a bit of storage. The light frame and hip straps gives extra support. For someone that hates feeling like I'm carrying a ton on my back, that's great! Built in rain cover is brilliant.


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

I love this backpack and would recommend it to all my hiking/outdoors friends. I ordered the blue one in s/m and am going to return it for a xs/s because it is a little loose even if I tighten it the entire way. The backpack has a lot of cool features and compartments and is perfect for a day hike. The blue is super bright and stands out which is nice so you can be seen easier and better. Overall this backpack fits pretty well, I just need a smaller size, but its comfortable overall.

Immediately in love

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

I ordered this pack to replace my really old camelbak that I use for everything from campus, to travel, to day hikes. After patching the patches on that one I decided I wanted something similar but a bit bigger, as that was the camelbak's only drawback. I found this little gem, on sale, in a nice color, and in a sized version that had an xs/sm fit. I knew that this had the venting panel in it but did not expect the pack to be so rigid - it has a full frame from top to bottom and a molded back where the pack meets your hips for the belt. Taking it out of the package I was initially disappointed because it was heavier than I had anticipated. Putting it on however, my mind was immediately changed. Never have I put on such perfectly comfortable pack. I couldn't be more in love. Usually fitting stuff like this means choosing the lesser of a few evils - I'm 5'1" 110lb. a shorter torso, and wide hips for a petite gal. This fit like a glove, though. The color is certainly more like forest green than 'stealth grey', but still pretty and not at all obnoxious. This is a much more robust replacement than I had been expecting, but I'm stoked because it will fit a wider range of niches - closing the gap between my old pack and my backcountry pack.

Such a great day hike pack!

    I bought this because I needed something a bit bigger than my daylite and something much, much smaller than my aura 65. This pack is perfect for day hikes! I went to Zion for New Year's by myself, so I loaded it up with snacks and water and plenty of layers and the suspension system made it feel so much lighter than it was! I used it three days in a row for 20+ miles and it never gave me any trouble except for when I put my iPhone 6 in the hip belt pocket because it was too large for the pocket so it rubbed me a little bit on my hips but that is not the pack's fault. I'm definitely in love with this pack and those stow on the go trekking pole straps really came in handy on angel's landing! I'm sure you could use this for short backpacking trips too because it has the the awesome removable sleeping pad straps on the outsideEverything was super accessible!

    Such a great day hike pack!

    Didn't work for me...

    • Familiarity: I returned this product before using it

    The shoulder straps rubbed my neck. I'm a short lady, 5'3, so i'm unsure if maybe i got the wrong size or it just simply didn't fit me right. And though i love the idea of a ventilated back, it compromised a lot of the space inside the actual backpack and for me it just didn't hold enough items. Everything seemed tight (added layers, first aid kit, survival kit, snacks, etc) it just simply wasn't big enough. All the room was at the bottom which made it awkward and became tight and narrow towards the top. Now the backpack in itself isn't bad, it actually is a very nice one. It's comfortable and light and its very padded around the waist and straps.. The color (i got the grey) was beautiful. I really did want it to work, but it just didn't.

    I've since returned the backpack and trying the Osprey Escapist, fingers cross this one works. I didn't realize how difficult finding the right pack would be!

    Hey Nicole, the size may have affected things for you... not sure without seeing it. But the measured size is 24L, even with the vented backpanel. It is as large in capacity as any other 24L pack. However, packs and fits are definitely specific things, so I hope you love the Escapist! If not, please consider the Tempest.

    Good luck,

    Great all around pack - skiing too!

    • Familiarity: I've put it through the wringer

    I love Osprey packs in general - as they are very well thought out. I generally use them for hiking, climbing and backcountry skiing.

    I needed a larger pack for day trips to accomodate extra layers and equipment, so i tried this one out.

    what i love:

    1) ah, the women specific fit! I am petite and the XS/S fits me so well, it's a pleasure to carry it. Never too long or awkward

    2) Super comfy hip belt with good pockets - minus 1 point as the new iphones don't fit in them. Still they are perfect for small snacks, sunscreen, tissues, whatever you need handy on the go

    3) the mesh back panel really does wonders for ventilation and keeping moisture from building up on your back

    4) the trekking pole stow straps are super handy for ice axes too

    5) i can easily strap skiis on the top side straps & sleeping pad straps.

    Love it!

    Great all around pack - skiing too!

    The perfect pack for smaller adventures

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

    Bought this for my wife and this is what she had to say about it:
    This pack was the perfect addition to my bag/pack addiction. I used this all last summer for day hikes from Timpanogos Peak to Southern Utah and in between. Started using the pack this winter for snowshoeing and it has not disappointed. I would have preferred the pack come with a bladder so I don't have to switch out between packs, but otherwise it's great. Love all the pockets and the rain cover is a bonus.

    Hey Don, thanks for the great review. I understand about the reservoir request, but that would put this price around $150, or more.We do have a great hiking day pack with a reservoir: Mira 26.

    Enjoy that Stratos!

    great pack, makes life easier

    • Familiarity: I've put it through the wringer

    the added comfort from the space behind the net helps keep the sweat off you. worth every penny. belt, chest strap easily adjustable. lots of little benefits, pockets, place to put your poles. highly recommended. amazing quality. it'll last for years.

    wanted to like this...

    • Familiarity: I returned this product before using it

    I researched around for the perfect pack for day hiking and/or biking, plus some standard daily use. I decided on the Osprey for its name brand/quality and awesome features like the hydration compatibility, size, hip belts, integrated rainpack, and overall construction/back support. I like the offering of gray blue tones (not much of a pink/purple type girl). The pack came in and I immediately loved it out of the box......until I put it on. Unfortunately it was just too short. I couldn't get it to fit properly on my back and sit correctly on my hips, even with it loaded. The straps sat funny on my shoulders. I will add that I have a pretty athletic frame. Goes to show not all packs fit everyone the same. I was able to return it and then settled for the Deuter Airlite unisex (which I really LOVE). It's an awesome trade-out and extremely comparable to the Osprey in quality and capabilities.

    Hi Michelle, I am wondering if you purchased the right size Osprey for you. sounds like maybe no... i have an athletic frame as well and the pack fits like no other.

    thanks for taking the time to write,

    great midsize pack

    • Familiarity: I've used it several times

    this is a great mid size pack, we bought it for trips when we needed a little more than just a hydration pack. A lot of great compartments on it, comfortable on and when in motion even over longer hikes.

    great pack but...

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

    I was trying to find the perfect pack for my mom, and thought this was "the one". The pack is durable, feature-full, comfortable and great looking BUT I was really looking for all this in a slightly smaller pack. All of the smaller Ospreys are hydration packs, and my mom isn't really a camelbak user. I wanted a small but not tiny day pack which was not mostly designed for hydration sacs. We are keeping the bag finally, but unfortunately it is not as perfect as I thought and the search is still on for that perfect pack....


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

    While this pack is more comfortable to wear than my Camelback, the Camelback has many things that I like. 1) It offers a couple of small mesh pockets for small items (moleskin, lip balm, etc) that are easy to get to inside the small compartment. 2) and the main one for me, the water reservoir is in a separate zippered compartment. The Osprey design of weight distribution on the hips is more comfortable but I don't like the reservoir design at all. You have to almost empty the pack to put the full reservoir in place. I will use it on longer hikes for comfort but on half day hikes, will probably still use my Camelback. Wish Osprey would change the reservoir to a separate compartment. Also I can't find the strap compartment that is pictured on this pack.

    Soon fell out of love...

    • Familiarity: I returned this product before using it

    I bought this pack and immediately fell in love with it. The aqua blue color is brilliant, as well as all of the cool "doo-dads". The integrated whistle on the chest strap, included rain cover and of course the handy zipper pulls that were so easy to grab. Unfortunately I fell out of love with my pack the moment I put it on. While I really liked how the frame kept the pack away from your back and allowed you to carry more weight, I couldn't deal with the actual shoulder straps. Not only did they feel rough, I could not get them to fit me properly. They rode way high up on my delts and even rubbed the side of my neck. Thinking I got the wrong size, I tried the next size up (at a local store) to no avail. Being that I have broader shoulders, I thought maybe I would have better luck with the men's pack. So I orderd that one from Backcountry. The blue color on the mens pack is more royal blue and while I didn't love it as much as the women's color, it wouldn't be a game changer. When I tried this one on, same problem. Obviously we are all different in body types and sizes and for that reason, this pack is not for me. It seems like Osprey needs to place the shoulder straps a bit farther apart on the pack or else this will ride up on other people's necks as well. Returned the pack and ended up buying another brand that works wonderfully for me.

    * I tried the pack on empty and fully weighed down. Thinking I might be doing something wrong as this is my first pack, I took it to a local gear store and brought the pack with me. No dice. Osprey packs just do not fit me.

    Hi Alisha, thank you for writing. My name is Leta Kalfas and I am a rep for Osprey packs. I am so sorry that the straps didnt fit you! Please know that packs fits are very personal, and although this pack didnt work for you, I am sure that we have lots of others that might fit you well. I often equate pack fit to shoe fit... not every pack will fit everybody, but I wish it had worked for you!
    So, please do not write off Osprey as a pack for you for the future... again, our packs have different attributes and features from one series to another, so please don't lose hope!
    Most importantly, I am glad you found a pack that does work for you and that you love. There are other pack brands out there that make good product, so I am happy you found what's right for you.

    Thank you for taking the time to write,


    I had the exact same experience! Love the quality, color, and features of Osprey packs, but the shoulder straps also cut in at my neck, and I am petite size, but with wider shoulders. Went up to a medium, too big of fit, and same shoulder strap issues. Would you mind sharing what brand of pack worked for you? I am going on a trip in a month and really need a new pack so any recommendation is appreciated. Thanks!!

    Great Day Pack

    • Familiarity: I've used it several times

    I've taken this pack up Mt. Whitney, Mt. Wilson and the Inca Trail. It is perfect for day hikes and super comfortable.
    The grey color is actually green. Not sure how they decided it was grey.
    I used it as a carry on to Peru and it fit nicely under the seat.
    I take a 2 liter camelback in the hydration pocket and also a 1 liter nalgene inside. The only issue I have with the pack is that the hydration sleeve can be hard to get to if there's anything in the top pocket. I had some frustrations wrestling with that.
    The main pocket can seem small, but I've stuffed a ton inside. No problem getting all your layers in for a long day.
    I also love the stow-n-go feature for your trekking poles. I don't use my poles often but always carry them with me. When they are secured on my pack I don't even notice they are there.
    As far as fit, I am 5'8, 150 lbs. I measured my torso at about 20 inches and the small/medium fits me just fine.

    Could you use this for skiing too?

    Hi Maggie,

    You could, but I wouldn't recommend it; it would probably make skiing difficult. The AirSpeed backpanel will be pushing the packs weight farther behind you, encouraging you to stay in the back seat while skiing. I definitely wouldn't recommend using this as a touring pack.

    Feel free to reach out and we can find a ski-able pack for you.



    Are the 2 side water bottle pockets large enough to easily slide in a 32oz nalgene?

    Is the Summit Blue color accurate? I've seen several different hues of Blue for this pack.


    Hey Bernice, it's Leta with Osprey Packs. The Summit Blue color is super close, but the actual is maybe a tad brighter than what the picture shows. It's beautiful! I went to my sample room and pulled it up to my computer to check. I think you will love it. Hope that helped!


    I want to buy this bag for my girlfriend. She is 4'11" is it fairly safe to assume the xs/s would fit here best?

    Hey Chris,

    Depending on torso length, the XS/S will be the best option.

    Osprey will also most likely be the best company to look at for a smaller pack for her torso.

    Shoot me an email anytime you have questions!

    Unanswered Question

    For anyone who tried both, how does this...

    For anyone who tried both, how does this compare with the Osprey Mira ? I'm debating between the 2 of these as a gift for my wife for mother's day. It will be used for day trips with the kids (zoo, theme park etc.).

    What's the right size for someone 5'5" and...

    What's the right size for someone 5'5" and ~130lbs?

    Your height and weight don't matter as much as your back and waist measurements.

    Measure from the big knobby vertebrae at the base of your shoulders to the middle of your sacrum(the flat bit at the middle of the back of your pelvis).

    If you're 17< I'd go for the S/M

    If you're 16> I'd go for the S/XS

    (I'm serious, it's VERY small, I usually wear an XS(I'm 17in) and I wear a S/M in this pack)

    On this pack, the waist measurements are a little off and don't really matter 'cause they top off at the same size and it's not interchangeable, but the measurements are:

    XS/S: 24<

    S/M: 26<

    But I'm 25in and the S/M fits me nearly perfectly.

    How do I know what size to get? I am 5'5" but have a somewhat long torso. Is the pack adjustable?

    Go get measured at any store that sells them. The size is based on the length of the top of your hips to your c7 , I am 5'6.5" and I need a small because my torso was 17". You can't really just go by your height.
