Backcountry Backpack

A ski touring backpack with an emphasis on fit and durability. The main cargo compartment can also be accessed from the rear panel. The webbing belt can withstand impacts from steel edges and can be attached to skis or snowboards. Features include an avalanche tool pocket, built-in helmet holder, and more.

Simply remove the shoulder straps, turn the backpack to the front, and it features a large U-shaped opening for easy access to your gear, even with the hipbelt on. The shoulder straps and hip belt feature ventilation mesh, multiple pockets including one for avalanche gear, webbing for attaching skis or splitboards, and a carrying system that hugs your body as you move. I am.

In 2009, Klettalmusen became the first outdoor company to use recycled polyamide in all its backpacks. Klettalmusen backpacks are made from fishing nets (used aquaculture and ghost fishing nets), fluff (used nylon carpet tops), plastic industrial waste, and scraps of thread and fabric. It is a 100% recycled product.

Main Fabric:
Retina®, Econyl® 400D
40% Polyamide, 30% Post-Consumer Recycled Polyamide, 30% Pre-Consumer Recycled Polyamide, 400D, 251 g/m , PU Coating, SkylCoat, bluesign® Approved Fabric, GRS - Global Recycled Standard, Fluorocarbon free
The idea for Retina® 400 Denier Dobby was to create a fabric for use in mid-range packs with an emphasis on durability and sustainability. These packs are used for climbing, where you're carrying a heavy load for long periods of time on the trail, experiencing friction from the surrounding nature, and being dragged up against rock walls. In order to meet these demands, the fabric is made with a dobby structure, and the surface is coated with a sky coating (surface coating) to make it water repellent. By applying the coating in this way, the water repellent function can be maintained for a longer period of time. The back has a PU coating with a water pressure resistance of 1500mm. The surface fabric is made of 400 denier ECONYL® fabric. ECONYL® is a recycled yarn made from polyamide that is 50% post-consumer recycled and 50% pre-consumer recycled.
Polyamide (nylon) is a synthetic fiber made from petroleum that produces extremely strong and versatile fabrics. Klettalmuthen uses recycled polyamide from industrial waste and post-consumer sources. For those of us who want to encourage people to send their used products for recycling, post-consumer waste is the first choice. Post-consumer waste materials used in recycled polyamide include discarded industrial fishing nets, old carpets, and hard fibers. Recycling polyamide adds more complexity to the production process, but the result is a reliable, long-lasting material that is lightweight, quick-drying, wind-resistant, and reduces waste while saving energy and resources. You can use what is. In 2009, Klettalmusen became the first outdoor company to use recycled polyamide in all of its backpacks.

65% Polyamide, 22% Polyester, 13% Aramid, 270 g/m2 – Bottom
By interweaving aramid fibers and elastic fibers, we create Kevlar® fabrics that are stretchy, soft, and highly durable. Kevlar fibers of different qualities are used for different functions and types of applications, making them unparalleled in ensuring durability and functionality in areas exposed to high amounts of wear and tear. . Typical applications include cuffs, storm flaps, knees, and the bottom of backpacks. All aramid fabrics used are Bluesign approved.

Backpack Technology:
4-S system - lightweight load transfer system
Klettalmusen's latest chest strap feature. Replacing the traditional sternum strap with a cord system provides greater adjustability and control. The cord can be freely placed using the loop webbing system. This adjustability makes it easy to adjust the tension and allows for quick changes on the move. Lightweight cords and hooks transform a traditional static sternum strap into a dynamic tool.

Measuring Guide

Back ultra measurement guide Locate the 7th vertebral body with your fingers. This is the part that sticks out when you tilt your head forward. It is important to keep your head straight when taking measurements. It might be a good idea to ask someone to help you. Start at the 7th vertebra and measure to the top of your hipbone. (Tip: Place a webbing belt around your lower back at the top of your hip bones so you know how far down to measure).
