    Good quality backpack. Osprey backpacks are great for hiking. The adjustable shoulder straps for torso length, make this backpack fit and wear great.

    This is a fantastic backpack for day trips without overnight stays; it fits everything you need. I especially like the color. I used to have a backpack without a ventilated back, but I'm enjoying it much more now. Perhaps my shoulders aren't very broad (I'm 176 cm tall), but the straps are a half-centimeter further across my chest than would be ideal

    I have herniated discs in my neck (C6/7, C5/6) and a bad lower back but love to hike. I went to reddit for advice and Osprey was the only consensus answer I saw. I tried several ones on before a big trip to Europe where we averaged about 25k steps per day hiking and walking everywhere. It's by a long shot the best backpack I've ever worn, the adjustability of everything makes it a no brainer for anyone. I'm going to need neck surgery but you never would have known it after wearing this with ~30lbs in it every day for a week on those long days.This is the type of item that you get excited about during the day and you can't remember why. It makes me want to hike when I'm at work. I feel like a little kid who got an action figure he can't wait to go home to play with. I'd give it 10 stars if I could.

    A great product! All around great quality and fit with comfortable chest strap and waist belt. The main feature I love about this bag is the mesh back and how it keeps the backpack away from your back. This is awesome if you get hot or in sweaty climates. I also noticed that i bladder cooler since it's not sitting against my back.Fantastic bag. I bought it specifically for seven day trek to Machu Picchu and was very impressed.

    Der Rucksack ist richtig angenehm zum tragen und bietet viel Platz. Die Verarbeitung hat mich positiv überrascht, vor allem die Regenhülle wird sich noch als nützlich erweisen

    Ce sac est super confortable comparés à mes précédents. Les bretelles ne font pas mal aux épaules même après des randonnées des 3h. Il est super bien pensé avec sa poche réservée au sac de couchage et la poche du milieu permettant de mettre des couche de vêtements rapidement equipables pour les changements brusques de météo. Les filets sur les côtés sont larges en bien élastiques pour ranger rapidement sa gourde. La ceinture au niveau des hanches est ferme ce qui permet de bien repartir le poids dans les jambes. Les coutures sont résistantes et le sac respire la solidité. Je suis totalement satisfait de cet achat.

    I've owned several Osprey sacks over the years and as a day sack this one didn't disappoint. The 24Ltr is perfect for my needs for days out in the Scottish Highlands . The side pockets can easily carry a litre bottle each , safe and secure. The frame size can be adjusted to suit the length of your back and the chest and hip straps are made with comfort in mind.

    first off, as of 03-04-2024, this listing says "Stratos 24" but the pictures are of the women's version "Sirrus 24." What I received was the correct item as listed (Men's Gray Stratos 24).I had the older version of this pack. It got very little use. It mostly hung in my closet for 7 years or so. I pulled it out last weekend to find that the interior was shedding. I guess it's the waterproofing backing and this is referred to as "delamination." If it happens under warranty, Osprey will replace it. Unfortunately I had 3 other smaller packs from several brands that were also falling apart inside. These hiking packs are made with a cheap, lightweight material that is NOT intended to last.If you are going to USE this pack as intended, then it's probably the best hiking pack in this size you will find. The reason I hadn't used it for so long is that I was willing to compromise and just take my every day pack on day hikes, rather than keep two fully stocked packs, or move all my relevant gear between two packs. And this Stratos 24 is NOT a good EDC pack. The non-removable massive hip strap makes it useless as an EDC pack but great as a hiking specific pack.The few changes that were made since the previous version are mostly all for the better. The only question for me is the outside of the pack feels more plastic compared to the old pack that was more fabric feeling. The new pack is definitely more crinkly and not only because it's not broken in yet. It's probably a recycled material but feels cheaper. The other small changes like larger front pocket and updated simple yoke adjustments, make it better though. The only other major change is the size of the frame is larger. It's much taller, and possibly wider. I guess the pack is not as deep compared to the old pack (I'm not sure, but if it's still 24 liters then it must be). I don't love the larger size frame since it was already a very large pack for day hikes. I suppose it's more of an overnight pack, so most people would probably see the larger frame as a positive. I had a Talon I had bought for day hikes, but it's also delaminating and I wasn't going to replace them both.If you buy this pack expecting it to last 5-7 years then it's amazing. If you expect it to last the rest of your life, then keep looking for a more durable long term material (500d Cordura, etc), or research how to store backpacks to prevent delamination. Probably a humidity thing if I had to guess.

    Great bag I love it! The color gray looks so much better than the product listing. Should function really well for my day hike in the high elevation mountains. Looking forward to my trip with this bag!

    I purchased this hiking backpack for my hiking adventures in Wales, Europe. We spent 3 weeks hiking in Wales and I knew I needed a good hiking backpack for day trips. This was the perfect size for me. I had plenty of space for a full change of clothes, a thin down jacket, snacks, a hat and gloves. This bag has straps for walking poles. I absolutely love the ventilation system. This system kept my back dry during long hikes. I also love how the pack is adjustable. I could adjust the pack for my height and while doing so the pack did not feel uneven. The straps on the top of the bag are great because they allow the pack to fit closer to your body. This pack has so many adjustments it’s really perfect. I ended up using the rain cover during one of our hikes when we got caught in the rain. The rain cover was also nice when we went walking under a waterfall. I also like this pack because it can be used as a carry on. I used this pack as a carry on while flying from Atlanta to London. I will not that due to the airspeed ventilation system you wont be able to just cram the pack in any old space. The height is really the height. The zippers were great throughout my trip. They are quality zippers with small straps on them to help pull the zippers in either direction. Osprey packs can tend to be expensive but you can catch them on deals from time to time. They are well worth the money for the functionality you get with their packs.Right out the box you could tell how durable the pack was. Osprey makes some quality products.
