Gjöll Rain Cover


Gyol rain cover [35-50L, 55-75L]

Waterproof Backpack Raincover

Gjöll is a simple and lightweight rain cover. Protects your backpack from the rain and fits all Klettalmusen backpacks from 35-50L, 55L-75L. It's made from 100% recycled 68 denier ripstop material with a water pressure rating of 10,000mm and an elastic bungee cord that allows it to be adjusted to fit snugly around your pack. There is a hook in the center to secure the cover to the back of the backpack, a reflective print on the front of the cover to increase visibility, and the rain cover can be stored in its own pocket.

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.

From clothing to backpacks, we developed Molle® because the quality required of fabrics varies widely. This polyester fabric is specially made to be resilient, strong and durable. Molle® also meets our strict demands for sustainability and quality. Polyester has little water absorption, excellent abrasion resistance, high tensile strength, and is extremely wrinkle resistant. This makes it ideal for outdoor packs and clothing.

Size Chart

Back length measurement guide

Locate the seventh 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).
