Kepler Men’s Short Sleeve – nature’s original technical base layer. Kepler is made from 100% pure merino wool — soft, breathable and built to perform, with zero synthetic fibres to get in the way. Just natural temperature regulation, pong-free freshness and all-day comfort, straight from the source. Supernatural comfort. No-fuss performance. • Pure merino wool – warm when it’s cool, cool when it’s warm • Naturally odour-resistant – wear for days without washing • Ultrafine fibres (17.2 microns) – soft on skin, never itchy For early starts, long days and everything between Kepler Short Sleeve is a go-to for hiking, running, bikepacking or everyday layering. The 160gsm fabric regulates heat across conditions — cool enough for summer efforts, warm enough for crisp morning starts. Its natural elasticity and low-profile seams make it ideal under a midlayer or pack, and the pure merino construction means it won’t hold odour even after heavy use. Soft, breathable and itch-free, Kepler gives you reliable comfort without the bulk — and without the need to overpack or overwash. Lower impact. Longer lasting. Naturally better. Kepler is made from 100% non-mulesed merino wool. It’s renewable, traceable, biodegradable — and backed by our 3-Year Alpine Bond. Wear more. Wash less. Go further.
The better you look after this merino garment, the better it will look after you. Give your Kepler a long, happy life with these tips: Hand wash your merino in lukewarm water, or gentle machine wash. Darn any holes as soon as possible so they don’t grow. Avoid snagging, vigorous machine washing, putting your finger through the fabric, and hungry moths.
