A lightweight down jacket developed for alpine climbing that can also be used as insulation, using only the highest quality 800 fill power white goose down. The 2023 updated version has increased the down weight to 150g. Versatile and great for any situation that requires warmth. It's packable and highly portable, so you can take it anywhere.

The slim cut allows it to fit under a shell jacket, but it can also be worn on its own if you're not in heavy rain. It comes with an adjustable 3D hood that contours to your head without obstructing your vision. The raglan sleeves are designed with an emphasis on ease of movement, and the long sleeves extend from the ribs to keep your wrists warm. Like all down products, the outer fabric is made from recycled polyamide.

At Klettalmuhsen, we only use the highest quality 800+ fill power goose down for insulation in our down products. Therefore, with proper care, it will maintain its shape and insulation properties for decades. All Klettalmusen down is RDS certified and all down is fully traceable back to the farm.

All Klettalmusen down products use box construction. The inner sidewall is used to distribute the down evenly, with no through-seams. Box construction creates a completely windproof layer that maximizes the warmth of goose down, resulting in down clothing with no cold spots or wind leaks.

[ Fluorocarbon free】
Polyamide (nylon) is a synthetic fiber originally made from petroleum that produces extremely strong and versatile fabrics. Levitent® is a polyamide-based fabric that uses a variety of recycled materials, including bio-based and virgin materials. 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. Levitend®, which is used in the surface fabric of down products, is a recycled material made from bioresources such as soybeans. The diamond weave structure gives the surface a soft feel. This pattern creates a slight distance between your body and the garment so it doesn't cling to your skin. It also provides a dry feeling even with active use. It is lightweight and wrinkle-resistant, making it ideal for packable items for active use. The tightly woven fibers provide protection from the wind. The fabric also uses PFC water repellent and can be used as a light shelter.

[ RDS Certified Down】
At Klettalmuhsen, we only use the highest quality 800+ fill power goose down as insulation for our down products. Therefore, with proper care, it will maintain its shape and insulation properties for decades. All down used by Klettalmusen is RDS Certified (Responsible Down Standard). Being RDS certified means the entire supply chain has been audited and the bird's life is respected throughout its lifecycle. For example, live plucking and force feeding are strictly prohibited and all down is fully traceable back to the farm. Klettalmusen chooses to use unbleached down that does not contain chlorine, so the few feathers in all our down products will darken. If there are any feathers showing through the outer material, gently squeeze or shake until the feathers disappear.

[ Box Construction】
All Klettalmusen down products have a box structure. Rather than having through-seams, the inner sidewall is used to distribute the down evenly. Most down products on the market use a single seam between the outer fabric and the inner fabric, which creates thousands of tiny holes that allow air to pass through and eliminate much of the down's insulating properties. Masu. Box construction creates a completely windproof layer that maximizes the warmth of goose down, resulting in down clothing with no cold spots or wind leaks. Box construction combined with 800+ fill power down provides superior thermal efficiency at significantly less weight than traditional construction methods.
