100% genuine New Zealand merino wool makes our Kepler short-sleeve top ideal for a smorgasboard of mountain activities. 

Whether you’re hiking a GR route on the continent, biking through Scotland, running on cool mornings, or heading out for the Alpine summer, your base layer should keep you dry and comfortable.

The lightweight baselayer top is a staple piece of most peoples layering systems. Kepler fits right in there with its excellent performance over a vast range of conditions. Quite simply it is a garment that does many things really rather well.

Breathable, wicking, fast drying and famously odour resistant, merino can be worn in the hot, in the cold, in the wet and in the dry. For all round comfort over extended durations merino is our baselayer of choice.

The short sleeves leave your arms exposed, increasing breathability and articulation, but be sure to cover up in the sun! Kepler is designed to be worn snug, but doesn’t need to be so skin tight that you feel self conscious in the pub at the end of the day.

Flatlock seams and an anatomical cut enhance the natural next-to-skin comfort of merino.

MERINO

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.

Kepler is made using only the finest sustainably sourced non-mulesed New Zealand merino.

Merino wool is a natural material with properties that make it ideal for the changeable conditions you will experience during mountain activities, maybe that’s why New Zealand Merino sheep look so content strutting around their hillsides.

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.

Great base layer for hiking.

My go to hiking base layer for any type of weather. Keeps you warm and dries fast. Highly recommended.

Quin
Great fit

I am 6', 39"chest and 31" waist - no I have not mistook Alpkit for a dating site! I chose the small size and this fits perfectly, close but not tight, perfect for adding more layers on top when needed. The quality is great and the price too.

Wild Running Top Mens Winter Running Gear

Sim Bensons ideal winter running gear

Merino wool base layers are normally the warmest, and as long as they are ethically produced you can feel happy wearing a natural fibre. I wear either my Alpkit Kepler (RRP £29) or my Howies short-sleeve base layer (RRP £45) pretty much all the time. They look great as well as performing brilliantly in all but the warmest weather. Synthetic base layers dry faster than Merino, but Merino retains its warmth even when wet

Women Climb Kepler Merino Top Review

I love the design of this women specific base layer top. It looks as good on its own after a hard day of climbing as it does at the crag under all your layers. The people at Alpkit have clearly thought about every aspect of this garment and tested it out to create a beautifully designed and functional garment that is perfectly fit for purpose

Second Summit Kepler Review

Second Summit put Kepler to the test

Hard to beat for the money. Well made, warm, dries well, comfortable and stays odour free. Great product from Alpkit, and one that would be well used on multiday trips. Order a size down if you like athletic fit.
