Kepler Women’s Long Sleeve Zip – natural performance, extra control. Kepler Zip gives you all the breathable, odour-resistant comfort of pure merino — with a front zip for easy temperature control on the move. No synthetics. No pong. No itchy and scratchy.

Pure merino comfort with on-demand ventilation

  • 100% certified merino wool – breathable, insulating, odour-resistant

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

  • Front zip offers instant cooling when the pace picks up

  • Long sleeves for warmth, sun protection and layering ease

Comfort that adapts when conditions shift

The Kepler Zip is ideal for days when your effort and environment constantly change — whether you’re starting before sunrise, hitting steep climbs, or moving through exposed terrain. The 160gsm merino balances insulation and breathability, while the zip neck gives you fast, fuss-free airflow when you need it most.

Merino’s natural anti-microbial properties mean you can wear it for days without washing — it stays pong-free and fresh through long hauls and multi-day trips. The shaped fit moves easily under mids or shells, with flat seams to prevent rub from rucksack straps.

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 — and designed to be worn again and again with less washing, less plastic, and less impact. Backed by our 3-Year Alpine Bond.

How to Measure

This size chart indicates the body measurements our garments are designed to fit. Measure yourself as described below, and use the size chart to find your size:
Chest - Measure around your chest at the widest part. The tape measure should pass under your arms, and be level from front to back.
Waist - Measure around your waist at the narrowest part.
Hips - Standing with your feet together, measure around your hips at the widest part.
Sleeve - With your arms relaxed by your side, tilt your head down and ask a friend to measure from the bone at the base of your neck, over your shoulder and down your arm to the fold at your wrist.
