Stratos 50 Osprey hiking bag

The Stratos 50 bag is ideal for long hikes in the mountains and on the roads to Santiago de Compostela.

The Stratos 50 is of an exemplary finish. It incorporates a stretched mesh back for maximum comfort and ventilation (especially when it's hot). This AirSpeed™ back system is fully adjustable and ensures optimal carrying with a backpack close to the body while benefiting from very good ventilation.

Many straps are available to adapt and adjust the bag according to your morphology (sternum strap, compression strap on the sides, strap at the waistband).
In case of rain, simply deploy the integrated waterproof cover (robust nylon raincover), thus instantly protecting your backpack and your equipment.
The Stratos 50 bag has a flap with a double clip and drawstring opening. The flap incorporates a large easy-access pocket. An expansion pocket located on the front is ideal for storing wet or spare clothes.
Access to the bag is facilitated, offering direct access to the main compartment thanks to a vertical zipper.
It is therefore not necessarily necessary to open the flap.
For treks lasting several days, removable external straps make it possible, for example, to attach a groundsheet.
A zippered compartment is available in the lower part to slip a sleeping bag.
There are many additional storage compartments: two zipped pockets in the waistband, double mesh side pockets and pockets under the side compression.
The Osprey "Stowon the Go" system allows easy attachment of hiking poles (or ice axes), simply pass the poles through the two elastic loops.

The Stratos 50 is compatible with Hydraulics™ reservoirs.
