Organic Merino Wool T-shirts

Organic Merino Wool

Wool outperforms any other fabrics when it comes to moisture wicking, warmth, and odor fighting capabilities. At Klättermusen, we use 100% Merino wool, known for its quality, softness, and ability to regulate body temperature even during high-intensity activity. Wool fibers have scales that are removed to make the fiber soft and comfortable using a unique process that is chlorine-free.

Tencel® T-Shirts

Tencel®

Tencel® is the brand name for lyocell, a fiber that is more absorbent compared to cotton, softer than silk, and cooler than linen. Key to using Tencel® next to skin are the natural anti-bacterial properties that come from the moisture being transported to the inside of the fiber which prevents a film of water from forming on the fiber. Tencel® is a regenerated fiber, meaning that it's made from wood pulp that has been dissolved and made into a fiber. It's a cellulosic fiber like viscose, but uses a production process that is gentler on the environment. Tencel® requires less energy and water, no chlorine is used and the waste products are minimal and considered harmless. When a product made of Tencel® has reached the end of its life length, it can be recycled and is also biodegradable since it's made from cellulosic fiber.

GOTS Certified & Organic Cotton T-Shirts

Organic Cotton

At Klättermusen, we work exclusively with organic cotton to lessen our environmental impact. Conventional cotton is considered one of the most polluting crops due to the heavy use of pesticides and insecticides in production. There are also concerns regarding worker’s rights, child labor and unsustainable water consumption. Organic cotton is grown without any pesticides, chemical fertilizers or GMO crops. Instead methods like beneficial insects and mechanical weeding help to reduce the environmental strain on the crop. Cultivation is done with care for the environment, and workers are protected from hazardous chemicals in their work, and also the surrounding communities by preventing the pollution of drinking water. We work with two different third-party certifications for organic cotton: GOTS-certification, the highest possible certification in the world of organic cotton, and the EU Council Directive on Organic Farming.
