We are a small family that loves all kinds of hikes around our state. This is our first pack purchase and all three of us purchased the Stratus/Sirrus pack (husband/wife/petite teenage daughter). We have used it for small 90 minute climbs, two-hours trails, and eight mile glacier hikes. I am impressed that we can pack it full for all kinds of weather conditions or pack it light for a short walk and it it comfortable. We do not use an Osprey hydration pack, we are using another brand and haven't had the issues others have mentioned as ours came with a magnet clip. It is a little difficult to load the hydration pack full of water though. We hiked to Grinnell Glacier in Glacier Nat'l Park last fall and I barely felt the pack on my back the entire time, I had it fully packed with my gear and lunch for all of us. I love all the pockets and found everything accessible the entire day. I don't carry my phone for pictures since I have another camera, I kept snacks in my side pockets so I they were a good size for me. All in all, we are all very pleased with this pack!

The ruska purple color on the website is much more purple than true color. I just recently purchased this pack and the color is much more maroon in person. I love this pack so far, great for day hikes!

This is the pack I've carried for longer day hikes or if I my gear includes some extra weight; it has the suspension and the load capacity to do that. I like the way the load rides--comfortable, stable, secure. The vented back panel is a bonus in the heat of southern Utah. The pack is fairly light but tough enough to endure many miles and abrasive conditions. The compression system is not entirely convenient, with side release buckles on the upper straps that are awkward but must be opened to fully access the main compartment. The reservoir loads easily through the main compartment, but only if I pull out most of the load. That said, the hip-belt pockets and a small shoulder strap compartment are secure but provide ready access to small conveniences and necessities as I hike. I also like the two smaller zip-pockets in the pack. The main compartment is roomy and opens wide to accommodate large items or to find things that settle to the bottom, and there are adequate attachment points and a couple mesh pockets if I need to carry something outside the pack. I've rarely used the rain cover except as a splash guard on river trips, but it's a worthy feature.

I got excited when I slid this bigger pack on and felt the most comfortable hip belt I'd ever worn. At the end of 8 mi, my back still felt like a million bucks. Unfortunately, I was never able to adjust the shoulder straps quite right, so by the end of the hike, my chest was sore where the chest strap/ shoulder straps cross and my arms felt chafed where they had rubbed the outside of the shoulder straps, even though this is a narrower bag made for smaller frames. Unfortunately, this was not the only deal breaker for me. 2nd deal breaker; hydration issues. 1.Bag not included 2. Awkward hose feed from main compartment to shoulder strap 3.Hose flop on shoulder strap (no magnet to keep it in place) 4.Lack of hose insulation sleeve (I don't want to carry water weight that I just drain on the ground because it's too hot/cold to drink because of exposure). I wasn't thrilled with the vertical zipper pouch. It's awkward to get into/see into and makes it hard to find what you're looking for without fishing forever or pulling everything out. The vertical zipper also wasn't very user friendly when I tried to just slide the pack around my body to quickly grab something one handed, like I used to with other packs with horizontal zippers. That said, at least the pack does have at least one additional compartment beside the cavernous main compartment where you're surely fishing for what you're looking for. For me, I'd rather have the main compartment split in half, with top, then mid access, as to organize/ find specific gear. I loved the bigger hipbelt pockets, but still couldn't fit my iPhone 6s+ (isn't that what they're for?) They did fit a pair of gloves, so bonus. The eyeglass pocket was bigger than necessary.. plenty of room to put a hook for keys, which was another item this bag lacked.

I use this for walking, biking and running. When tightened down, this pack doesn't shift at all when running, though you have to make sure it is perfectly adjusted otherwise it will shift off your hips. I can fit my phone into the hip pockets, but just barely. I hope Osprey considers making the pockets an inch or so longer in the future. The Airspeed suspension is pretty much the same as the Anti-Gravity and really does transfer all the weight to your hips. I found an instant improvement in my back pain I would get from lower-quality packs.

I have a wonderful Osprey Aura G5 SG backpack that I have used on many trips. I told my friend about it and he bought me an Osprey Sirrus 24 daypack for shorter hikes. I plan to take it on a hike tomorrow but am having incredible difficulty getting my hydration tube through the very small hole. It took me a while to even find it. On the backpack, the hole is large enough to push the tube through and also has a stretch fabric that lets you easily insert it. The only way to possibly get the tube through is to remove the bite valve which I really didn't want to do. Even then, it was very difficult. I'm envisioning water all over the place once I fill the bladder and try to load it. I'm going to work on it but wanted to post this review so that perhaps future packs would have the same kind of h2o hole that the Aura backpack does. I can't really recommend this pack because of this issue.

I use this bag on my 7.5 mile run to work. It's been excellent for all my needs. I originally was going to buy the Dyna, which is the lighter running bag that Oprey offers. But this bag seemed more durable. And I'm already running with 10 pounds. The extra ounces of material doesn't matter at that point. My biggest compliant about the Sirrus 24 is the lack of places to to hook on a safety light. I've tried hooking lights to the side pockets which usually works but when you stick on the rain cover there is no place for a safety light and that is when I need it the most. Also the rain cover could be a bit more reflective. Other than that I love this bag. I'm a smaller person. After trying fifty other bags at the store, I found this bag to be the most comfortable and adjustable. I can tie it tight enough for a sung fit that I need while running. The frame keeps the load suspended and from bouncing around. 24 liters is perfect for all my needs--winter wool coat, office work clothes, dress shoes, make-up--etc, dry shampoo and lunch. And it doesn't look or feel like a clunky hiking bag, so I can still walk into the office with it.

For the life of me, I can't find the opening to pass the hydration tube from the main compartment to the outside of the pack. Neither can my husband and he already has an Osprey pack with an obvious opening. I've been closing the zippers of the main compartment around the tube to keep it rom moving, but this just can't be right. I emailed customer service to ask about it but haven't received an answer.

Love the pack. Used it for a couple of long day hikes this past weekend. The big MISS on this pack (and on pretty much every other pack I looked at) was a CONVENIENT place to carry a phone. My phone is my camera when I travel/hike so I want to have a convenient, safe place to access it. I find it very frustrating that in 2017 they don't make a pack with a place to access a phone! The little pockets on the hip don't work for a phone - I have an iPhone 7 (not the Plus) and it's still too large to fit in the little zip pocket. Yes, I can get it in, but it is SOOOOO not worth the struggle. PLEASE consider this as an option in the future. Honestly for $130, it should be a standard feature. The only other comment would be to have another pocket on the inside to throw things in that is not just the deep pocket along the back.

Comfortable pack with good capacity and flexible loading options. I use it for hiking and skiing. One problem though - the opening for the hydration tube is way too small. It is difficult to get the bite valve, shut-off valve and clip through the slot. I didn't expect this flaw in a modern pack.
