The Kletter Sack is a revival of a heritage model developed for mountaineering, with details that make it suitable for everyday use in town. It is easy to use for both men and women, both outdoors and around town. When there is only a small amount of storage, you can adjust the position of the rain cover lower to give the bag a compact appearance that does not suggest its capacity. The zipper on the side provides direct access to the main compartment, making it functional and allowing you to take out items without opening the rain cover. Can store A4 size. X-PAC, a fabric characterized by its diamond pattern, is thin and light, yet waterproof and strong, making it ideal for festivals and outdoor activities. The cushioned shoulder straps make it easy to carry for long periods of time without getting tired, and the length can be adjusted to suit your preference.
