Osprey Stratos 50L Backpack

Product description Osprey Stratos 50L Backpack

Manufactured with the most rigorous specifications and the best quality offered by the American brand, the Osprey Stratos 50L backpack completely justifies its outstanding reputation as a hiking bag. Whether you are looking for an outdoor walk or climb the mountain on weekends, with the Stratos you will always feel the wind behind you.

Thanks to its AirSpeed™ suspension system seamless, the Stratos offers you a comfortable and smooth load that will not make you notice its large 50-liter capacity. Its 3D contoured rear panel ensures total breathability that will keep sweat and moisture away from your back, while its harness system is fully adjustable and includes additional sternum and lumbar belts for greater stability.

The Stratos’ utility is fully evident on the outside, with the inclusion of a Stow-on-the-Go trekking pole attachment that allows you to carry these valuable tools with you at all times. Also, an ice pick loop, a front panel vertical pocket, and dual zippered pockets on the suspension’s base make it easy to organize all your belongings without even taking your backpack off your back.

The interior of the Stratos has an incredible diversity of organization thanks to its multiple organization pockets, among which highlights a hydration reservoir sleeve fully compatible with the Hydraulics™ and Hydraulics™ LT series. When rain and the elements attack, this backpack also has an integrated raincover to keep your belongings dry. Stratos 50 brings true innovation and quality to the ventilated pack world.

Inspired by Ospreys AntiGravity´ technology, Stratos 50 provides a fully adjustable AirSpeed´ ventilated back system which combines single piece construction of the backpanel and hipbelt with highly breathable suspended mesh.

This allows for increased comfort in warm weather, even with a heavy load.

The classic styling and clean design, alongside an impressively comfortable carry makes the Stratos 50 a firm favourite for walkers and hikers and campers who are looking for a ventilated daypack with enough capacity for camping equipment and overnight gear, as well as plenty of extra layers and equipment for when the weather is changeable.

The detachable raincover stored in the bottom pocket increases weather resistance and tough nylon fabrics ensure durability.

Stratos 50 features a double-clipped lid opening with draw-cord fastening, a large, easy access pocket in the lid and a vertically zipped expansion pocket on the front which is perfect for securely storing a jacket or spare layer for easy access.

The side of the pack has a single vertical zip which allows access directly into the main compartment, saving you from having to open the lid top.

The base of the pack also features a zippered sleeping bag compartment with a bellowed divider, designed to allow easy separation of equipment.

Stratos 50 is the perfect pack for long days and lightweight camping trips in Spring, Summer and Autumn.

Stratos 50 is compatible with all Hydraulics´ and Hydraulics LT´ reservoirs.

Osprey stratos 50l


Exceptional backpack, light and practical. Flawless delivery!

Very good


Very fast delivery, the bag looks very good.

Best backpack I ever had


This backpack is ideal for 2-3 days hiking, lightweight, comfortable, and super functional, love it!

Like very much


It's very comfortable to carry, and the color scheme is also beautiful



Always been a big fan of Osprey ... the Stratos 50L is perfect for a hike weekend or a week light backpack! I am very satisfied with this purchase ... 5 stars ⭐️ and even more

Lots of storage.


I have the Stratos 34 and now I bought the 50. I couldn't find another one that had these features all together, rain cover, 2 side pockets at the waist and a place to carry water.



Very good bag. Lightweight, practical, offering many storage possibilities. Good finishes. Always satisfied with this brand.

Osprey stratos 50l


In my opinion, 50l is the ideal medium size for hiking. Beyond that, we tend to overload. For the bag, the carrying comfort is quite good. I was a little skeptical about the open pocket at the back of the bag but in the end, it turned out to be very useful: you can slip on a piece of clothing that will remain very easy to access. The pockets on the belt could have been larger (difficult to get in and out of his smartphone). In short, it is a good bag. Finally a last word but this time on the Trekkinn.com site, it's been several times that I order from them, without worry.

Meets my expectations


Very pleasant surprise when I discovered my bag. As described, light, well done, as always For this brand. A little delay but a good follow-up which reassures. I would come back to shop because all the products are serious, thank you.

Good backpack for routes of more than one day.


It is a light backpack and has the necessary accessories to make crossings or to make more intense routes. I recommend it for spring-summer and in autumn if the weather is temperate. Good value for money, worth investing in. The order arrived on time. I recommend it.

Très bien!


J'ai reçu le sac en 2 semaine! Le suivi est bien. Je recommande ce site ! J'avais un peu d'esitation face a ce site internet mais finalement aucun problème. Très bien trekking! Merci

My Osprey Stratos 50L


Osprey Stratos 50L is a perfect buy. I am very happy with the balance system of the backpack. Multi-sections of the bag provide great utility. Overall, must-have product. Thanks to Trekkinn & Osprey. NOTE:- Indian buyers, also take into consideration about the Custom fee and IGST, which further increase the cost.

Very Impressed


I was very excited when we received our hiking bags, the Osprey Stratos 50L is a lot more then I hoped for. The Osprey quality is always top class and never ceases to impress. So comfortable and light. Thanks trekkin for the great prices.



Good backpack for hiking, comfortable and with plenty of space. I recommend it

High Value


Comfortable with a nice price! Delivery is on time but just in a plastic bag, but glad it isn't broken.

Never received


Trekking is not a trusted site First order placed on this site and my different articles have never been delivered to me. Customer service very difficult to reach who when we have them asks us to wait and not to worry. But here is after a month and a package declared damaged by the carrier no refund I recommend this site for its lack of seriousness and its non-refund of undelivered packages

absolutely Amazing Bag and Purchasing Experience


the bag got delivered within three weeks of the date of purchase and is a fantastic hiking bag with a lot more room than you might expect out of a 50L bag. beautiful quality and fit, makes the bag feel light even while hiking with quite a bit of weight! would absolutely recommend this bag and specifically that you order it from trekkinn.com!

Very good


After a few days of testing, I find it to be the best backpack I've ever tried, very comfortable and ergonomic

Great backpack, love it


This is my first hiking backpack, spent a lot of time on watching reviews, comparing and thinking and finally decided that Stratos 50 is an ideal option for me. After 2 months of usage I am absolutely happy. It feels great and light on the back. All the detailing is qualitative. No cons at all till now.

Very well !


Fast delivery and quality material. Backpack seems so small but in which we house many things. I recommend !

Top quality


Osprey has proven to be the best manufacturer of backpacks. The attention to detail is what wows you when looking through the cleverly placed pockets and straps. In my opinion the best of osprey packs, especially because of the side access to the main compartment. Usually its such a struggle to get to that bottom packed item, but the stratos 50 makes it a whole lot easier!

First impressions


Excellent backpack, something more than small than I expected to be 50L but still as a great capacity and availability to store all the equipment and be able to accommodate it properly, the weight feels well distributed, and with a great support for long beds loading moderately heavy luggage, we must see the durability of the same backpack but there is more satisfied
