Bach says about the Specialist 90
Specialist 90L is our biggest trekking backpack made of remarkably durable material. Although it is a large volume pack, it is still light for its class. As the trail passes through dense vegetation, this backpack continues where most other packs would rip apart. Thanks to its suspension system it is also exceptionally comfortable to carry. Designed for backpackers and those who are heading on multi-day expeditions requiring a range of equipment or more room for food supplies. Having stretch side pockets, as well as various attachment points, allows for items to be securely stored, yet quick to hand.
