The climate neutral, PFC free Guide SL strikes the perfect balance between light weight, comfort and functionality. The comfortable, well ventilated back system; snug fit that keeps the load close to your center of gravity; ergonomic, detachable hip fins; hard-wearing materials; further improved attachment systems; and stowable rope strap all combine to generate fine-tuned load control and maximum freedom of movement on multi-day alpine projects. The J-shaped front zipper opening also provides quick access to the main compartment.
