Stratos 50

The wind on your back. Stratos 50 brings true innovation and quality to the ventilated pack world.

Inspired by Osprey's 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.

  • Internal hydration sleeve
  • Integrated & detachable raincover
  • Stow-on-the-Go™ trekking pole attachment

i own 3 osprey back packs ..26 stratos/ 65 ag atmos and stratos 50
i am sorely {literally} disappointed with the stratos 50.the main sack is fine but the harness and straps ..except for the waist belt... is poor only fit for the narrow shoulders..and the pack unable to cope with any weight over 15 kg...the pack swings from side to side on medium ascents or descents..no matter how balanced or well packed ...so i recommend to pass on this backpack ...go for the ag 50 litre or a deuter 45litre.
Osprey Customer Service, 

Hi,

Thank you for taking the time to write a review on the Stratos 50.

I am sorry to hear that you are having these issues. I can only assume that you are fitting the pack and packing it correctly but if you would like to double check this, and read our guide on “How to fit your pack” and “How to Pack your Pack” please do as it may shed some light on the issues at hand and help come to a resolution. With the load range of the pack being 12 - 18 kg there should be no issues with 15 kg in the pack.

If the problem persists, please do hestiate to contact us.

Regards,

Osprey Customer Service

Besser geht nicht
Seit etwa drei Jahren habe ich den Stratos 50. Ein absolutes TOP-Produkt, da wackelt nichts, zwickt nichts, drückt nichts. Sitzt perfekt(wie für mich extra gemacht). Alles festgezurrt und kilometerweit über Stock und Stein - und nichts lockert sich - sitzt einfach richtig toll. Die Aufteilung der Fächer ist ok und von Tages- bis Mehrtages-Touren alles perfekt verstaut. Rücken immer gut belüftet, Hüftgurt einfach top sowie auch der höhenverstellbare Brustgurt. Selbst mit dem neuen Kamera-Besestigungssystem von "b-grip" ist das Gewicht sehr gut verteilt, so das man meint nur halb soviel Gewicht am Rücken zu haben. Also ich schwör auf Osprey!!

Great backpack for almost every occasion
I've been using the Stratos 50 for quite a while now and I've been doing everything from hiking the Appalachian trail to backpacker travelling with it. I'm really pleased with the backpack as a whole and it is really comfortable to wear. The main compartment is roomier than one might think, and if you utilize all the compartments you could fit a lot into the backpack although it's kind of small. The side pockets are perfect for storing a water bottle while hiking or a pair of shoes while travelling.

The only con I could come up with regarding this backpack is that the top loading feature makes it rather hard to get to your stuff in a smooth way. Although the backpack is provided with a side zipper to make this easier, it is still quite hard to take something out without making a total mess inside the bag. My conclusion would be that if you're looking for a backpack which is good for travelling you might want to look into the Farpoint/Fairview-series instead, but if you're goal is to be hiking or sporting with a comfy backpack - the Stratos is an excellent choice!

Versatilidad y resistencia
Una mochila perfecta para cualquier trekking en el Himalaya. Aunque su capacidad es de 50 litros, los ajustes con correas nos permiten utilizar menos carga con total comodidad. La transpiración está garantizada y su facilidad de acceso al interior, tanto por el lateral con cremallera como por arriba, ayudan enormemente en su manipulación. Se ajusta perfectamente al cuerpo. El tejido exterior es muy resistente lo que me decidió por este modelo frente al Talón 44, más ligero pero aparentemente más delicado. Enhorabuena a Osprey por su trabajo.

Ottimo compagno
Zaino molto compatto e dalla dotazione completa. La capacità di carico può essere leggermente aumentata sollevando la patella il sistema di chiusura rende molto stabile il contenuto. Unica pecca, gli spallacci non sono particolarmente imbottiti, mentre lo schienale in rete svolge egregiamente il suo lavoro (testato in Guatemala con temperature e umidità non confortevoli). In definitiva un ottimo prodotto, di cui apprezzo soprattutto la compattezza e la quantità di accessori.

Stylish, comfortable, durable, very equipped, not too expensive
- the materials seems strong (even when brush many rocks) and well sewn.
- many and adjustable fastens. There are four fastens instead of the classical two to access the main pocket. I think it's unusual and a little slow to adjust, but it makes the backpack more compact and tight.
- there are many and large pockets.
- the back is solid, even the grid (i thought it was chewy and soft but it's not at all). It's easy and fast to find and adjust, even the chest and the belly. Unfortunately the chest belt is not elastic, but it's replaceable.
- the shoulders are very large, transpirable and confy. Almost no reddening after many hours of trekking.

I'm very satisfied and happy. I'd buy it again.

Great Size Great Features
This is a brilliant Rucksack. I went for this as I wanted the 50 litre capacity, the mesh which lifts the pack off your back and the built in raincover.

I used this on day hikes during bad weather in the Kerry Mountains in Ireland and it was perfect.

I initially bought the S/M as though I am 6 foot I'm skinny. I found that the back was not long enough I therefore changed to the M/L which was spot on.

un fedele compagno di viaggio
ho avuto modo di testarlo in una randonneè di 10 giorni all'interno dei circuiti vulcanici dell'isola di Reunion e non posso che tesserne le lodi, anche alla luce del confronto diretto con gli zaini di altre marche dei miei compagni di viaggio. Abbiam percorso 160 km sempre con lo zaino in spalla, con tutto l'occorrente per il viaggio in autonomia (circa 12 kg di peso) attraversando i più disparati ambienti, dalla foresta tropicale alla montagna, passando dal sole alla pioggia in più occasioni.
Prima di tutto, una volta regolato per le proprie dimensioni, ti scordi quasi di averlo sulle spalle per quanto è ben bilanciato, più dello zaino da 30 l che uso per le escursioni brevi. Materiali, chiusure e cinghie di compressioni tutte ok...è tornato a casa come nuovo! in più le varie cinghie di compressione aiutano a trovare sempre il miglior assetto di viaggio. Comodissimo poi il sistema di fissaggio dei bastocini senza la necessità di togliersi lo zaino di dosso.
Riassumendo, son molto contento dell'acquisto e di aver scoperto questa marca, forse non conosciuta come meriterebbe qua in Italia.
