What our customers are saying about Osprey Stratos backpack

Simply spectacular

2026/07/13

Osprey stratos 44

A really good backpack, it´s a bit heavier than it should be, but it´s made up for by how comfortable it is to carry and the space it has. It has many pockets and they are very well distributed and are gigantic. And the mesh on the back is very comfortable and offers great space between the backpack and your back to avoid sweating so much. It´s great, a very good item
