Alpine summer, Scottish winter, Autumn on the gritstone… You don’t want your base layer to be as seasonally limited as your outdoor activities.

A multi-day trip doesn’t have to leave you with a humungous pile of laundry. Thermoregulatory, anti-microbial, UV protective, and exquisitely soft, Kepler base layer keeps you comfortable and fresh on longer trips across a range of temperatures.

A high collar keeps your neck protected from draughts or the sun whilst the ¼ zip neck opening gives ventilation when needed. Thumb loops keep the full-length sleeves in place, ensuring your forearms stay well protected.

Flatlock seams and an anatomical cut enhance the natural next-to-skin comfort of merino. Kepler is designed to have a flattering fit that isn’t too ‘base layery’, so you’ll fit right in at the pub after a day on the hill.


The Kepler range uses beautiful, ultrafine merino for a luxuriously comfortable next-to-skin feel.

With thermoregulatory and anti-microbial properties, merino wool is more than a match for day-in, day-out use across the temperatures in changeable mountain conditions, help you to stay fresh, comfortable, and protected no matter what the weather decides.

We use 100% natural New Zealand merino from non-mulesing farms.

Product Care Information

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.
