Kepler Short Sleeve [Mens]

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, certified to the Responsible Wool Standard. It’s renewable, traceable, biodegradable — and backed by our 3-Year Alpine Bond. Wear more. Wash less. Go further.
