Kepler Women’s Long-Sleeve Performance Top

Description

Kepler Women’s Long Sleeve – nature’s original technical base layer.  Kepler is made from 100% pure merino wool — soft, breathable, and built to perform across seasons. No blends, no synthetics. Just nature doing what it does best.

Supernatural comfort, all-day performance

• Pure merino wool – breathable, insulating, and pong-free

• Ultrafine fibres (17.2 microns) – soft next to skin, never itchy

• Long sleeves offer warmth, sun protection and easy layering

Reliable warmth with natural stretch and softness

Kepler is your go-to for cool starts, breezy ridgelines, and long, layered days outdoors. The 160gsm fabric regulates your temperature across conditions — keeping you warm under a fleece and cool when the pace picks up. Merino’s natural stretch and breathability help you move freely and stay dry, while flatlock seams and a clean silhouette make it easy to wear under a shell, pack or harness.

Thanks to merino’s natural anti-microbial properties, Kepler stays pong-free for days — ideal for multi-day hikes, low-wash living, and fast-moving trips where every gram and wash counts.

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 biodegradable — built to go further with less impact. Backed by our 3-Year Alpine Bond and tested through years of movement, weather and wear.
