Kepler Men’s Long Sleeve – nature’s original technical base layer. Kepler is 100% pure merino wool — soft, breathable and built to perform wherever you take it. No blends. No synthetics. Just natural, low-maintenance comfort that keeps working day after day. Supernatural comfort, all-season performance • Pure merino wool – breathable, insulating, and pong-free • Ultrafine 17.2 micron fibres – itch-free softness against skin • Long sleeves for warmth, sun protection and layering versatility One layer. Endless use cases. Kepler is your year-round foundation — ideal for early starts, shoulder seasons and days when the weather won't settle. The 160gsm merino fabric wicks sweat, regulates heat and keeps you dry and comfortable, whether you’re wearing it solo or under layers. Soft, naturally stretchy and built with flatlock seams, it stays comfortable under packs or harnesses all day long. And because merino is naturally anti-microbial, Kepler stays fresh after multiple wears — no pong, no hassle. Perfect for multi-day trips, long-haul travel, or simply packing light. Lower impact. Longer lasting. Naturally better. Kepler is made from 100% non-mulesed merino wool. Renewable, traceable and biodegradable, it’s a base layer you can wear more and wash less — without compromising performance. Backed by our 3-Year Alpine Bond.

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.
