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.

Sustainability and Product Care
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.

We have dedicated Repair Stations in our stores and we're fully equipped to breathe new life into your old kit. This includes spare parts, patches, new zips and wash and reproofing of your down and waterproofs. Pop into any store or contact us online for more info.

How It Is Made

Non-mulesed Merino
We only use merino from certified non-mulesed sources. Mulesing is a practice some farms use to guard against parasitic fly strike. We believe this practice is cruel and unnecessary and something that can be easily prevented by regular shearing.

Natural Fibre Materials
Merino wool is 100% natural, biodegradable and renewable (sheep produce new fleece and sheep produce new sheep... usually in spring... they gambol... you know all this...)

Where It Is Made
Our products are made in the best factories in the world. We know the factories personally and they have all signed up to our Code of Ethics in our supply chain. This includes the Ethical Trading Initiative base code, fair pay, safe working environments, no child labour, no modern slavery, no bribery or corruption, no materials from conflict zones and humane farming methods.

All our factories sign up to our Code of Conduct. Find out where we make our product by visiting our Factories of Alpkit factory zone.

Reducing our carbon footprint
We are carbon neutral under PAS2060 and offset our Scope 1, Scope 2 and Scope 3 operations and transport emissions. We recognise that offsetting is not part of the solution but a point to pass through on a journey to Net Zero. Carbon Neutral is just a step in that journey.

We have joined the Science Based Targets Initiative which sets independent targets for us to achieve to do our bit to limit global warming to 1.5°C. Our targets are to halve our Scope 1 and Scope 2 emissions by 2025 based on 2018 base year and reduce our total carbon intesnity by 15% every year to achieve genuine net zero by 2050.

End of life
When your partnership with this product is over send it back to us and we will pass it on to someone that needs it through our Continuum Project.

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.
