Ultra-lightweight and super comfortable: wide, ergonomic vest-style shoulder straps with elasticated compression system, two adjustable sternum straps and soft material against the back create a garment-like fit. A stretch mesh inner pocket and side compression straps help eliminate load wobble no matter how challenging the terrain. A holster pocket on the front of one shoulder strap makes it quick and easy to access collapsible trekking poles. And there is space for soft flasks and a GPS in the shoulder strap pockets. The body fabric is made from 100% recycled materials and is bluesign® certified.
