Kepler Women’s Short Sleeve – nature’s original technical base layer. Made from 100% pure merino wool, Kepler is soft, breathable and built to perform. No blends, no synthetics — just nature’s technical fabric doing what it does best: keeping you comfortable, cool, and pong-free across every adventure.

Supernatural comfort. Easy everyday performance.

Pure merino wool – breathable, insulating, and odour-resistant
Ultrafine fibres (17.2 microns) – soft on skin, never itchy
Naturally temperature-regulating across hot and cool conditions

Layer it, live in it, go again

Kepler Short Sleeve is that piece you wear for days on the trail, then straight to town — because it doesn’t smell, doesn’t itch, and always feels just right. The 160gsm merino fabric keeps you warm when it’s chilly and cool when you’re working hard, making it ideal for multi-day hikes, hot weather runs, or as a layering base year-round.

The close, low-bulk fit layers neatly, while flatlock seams reduce rubbing under packs and straps. And with merino’s natural elasticity and odour resistance, you’ll reach for it trip after trip.

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, and built for less washing, less waste, and more adventure. Backed by our 3-Year Alpine Bond.
