A collaboration with Terrex, this adidas by Stella McCartney backpack lets you blaze new trails without compromising on fashion. It has straps contoured for a female physique and an adjustable waistbelt for extra support when the terrain gets tough. The 100% polyurethane film is water-repellent, with a pack-away rain cover for sudden downpours, keeping your gear dry. Multiple pockets, including a mesh one inside, organise essentials. Compression straps hold hiking poles or an ice axe when you're scaling new heights, and helps with bulk. Plus, the main material opens to the bottom panel for easy access to everything packed — no need to pull everything out. This product features at least 20% recycled materials. By reusing materials that have already been created, we help to reduce waste and our reliance on finite resources and reduce the footprint of the products we make.
