The concept for our Ultra Pure® shirts is to have a running shirt as pure and sustainable as possible.

Therefore we use for our Ultra Pure® Shirts only 100% extra fine non-mulesed 19.5 μ Merino wool from organically farmed livestock certified with Global Organic Textile Standard Certificates (GOTS) and Bluesign Certificates.

We also do not dye the wool, the Ultra Pure® shirts come only in undyed white.

All our Ultra Pure® shirts are knitted on Japanese 3D knitting machines, which means that the whole shirt is knitted in one piece without any seams. This is different to the manufacturing process of normal running shirts which are cut out of large pieces of fabric. This process creates a lot of fabric waste. Therefore we have chosen 3D Knitting  as it allows us to produce our Ultra Pure® shirts with almost Zero % textile or yarn waste. Only less than 3 grams of yarn waste are produced during our whole manufacturing process.

Over all we could honestly claim that our Ultra Pure® shirts are the most sustainable, good and ethical running shirts currently on the market.
