Why We Like The Perimeter 50L Backpack

We find our perfect fit with the Perimeter 50L Backpack. The torso adjusts for both height and width, accommodating our broader shoulders, while the waist belt adjusts to our narrow hips. However we have it adjusted, the spring-steel periphery frame collaborates with the back panel sheet to give us a stable, ergonomic fit.
