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.

  1. Quasi idéal
    Les + :
    - Confort irréprochable, j'en ai oublié les 12kg pendant les 15 jours
    - Dos réglable !
    - la compression du sac
    - les 2 poches sur la face arrière

    Les - :
    - Les poches ceintures pas très accessibles et un peu petites
    - j'aurai peut être préféré avoir la poche à eau à l'extérieur comme sur le Kestrel car 2 litres ca prend de la place

  2. Très bon sac à dos
    Je trouve ce sac à dos très intéressant. Les volumes sont facilement accessibles. C'est mon deuxième sac à dos Osprey. Les réglages sont simples et précis. Deux bémols : je trouve qu'on devrait aujourd'hui faire une poche pour un téléphone portable de taille moyenne, facile d'accès. Pour ma part lorsque le sac à dos est en place, il m'était difficile de glisser mon téléphone dans une des deux poches de la ceinture. Je trouve également dommage que la sangle au niveau du sternum ne soit pas réglable en hauteur.

  3. Apertura frontale
    Zaino molto capiente e comodo ma una domanda perchè invece di fare un'apertura laterale che è inutile non fate l'apertura frontale come per esempio nel Kestrel 68??? Sarebbe molto più comodo

  4. 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!!

  5. 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!

  6. 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.
