Supernatural comfort. No-fuss performance.
-
Pure merino wool – warm when it’s cool, cool when it’s warm
-
Naturally odour-resistant – wear for days without washing
-
Ultrafine fibres (17.2 microns) – soft on skin, never itchy
For early starts, long days and everything between
Kepler Short Sleeve is a go-to for hiking, running, bikepacking or everyday layering. The 160gsm fabric regulates heat across conditions — cool enough for summer efforts, warm enough for crisp morning starts. Its natural elasticity and low-profile seams make it ideal under a midlayer or pack, and the pure merino construction means it won’t hold odour even after heavy use.
Soft, breathable and itch-free, Kepler gives you reliable comfort without the bulk — and without the need to overpack or overwash.
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, biodegradable — and backed by our 3-Year Alpine Bond. Wear more. Wash less. Go further.

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.

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.
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.
