There comes a time of year where one pair of trousers just don’t quite cut the mustard. Wearing two pairs is hardly comfortable, so we created the Kepler Long Johns: slim-fit leggings for layering bliss.

Kepler Long Johns fits comfortably beneath your ski-suit, tech-soft-shell, or even your roomier jeans to act as a second line of defence against the cold.

Thermoregulatory, anti-microbial, UV protective, and exquisitely soft, Kepler merino keeps you comfortable and fresh for longer across a range of temperatures.

Cut for comfort, the high waistline stays away from where your other garments may sit in your layering system, a wide waistband prevents rubbing beneath your rucksack.

A low-profile, next to skin fit with ultrafine, soft merino sets the groundwork for your layering dream come true.


The Kepler range uses beautiful, utlrafine 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.

Great bit of kit

Had these for a few weeks now, have worn them numerous times when out cycling and they're superb. Really good quality, super soft and they keep you really warm. Great job Alpkit.

Fantastic quality and great service!

Ordered these as a gift - they arrived extremely quickly (despite all the christmas post) with a lovely handwritten note to say thanks! The quality of the material is absolutely fantastic - softest merino I've felt by a long way compared to Icebreaker, Crane etc. smile Definitely recommend!

Kepler Merino Review in Velome

Mountain biker Jessica Strange puts our Kepler Merino top to the test in South Wales

The top is really lightweight, soft and totally breathable which is ideal for a day's riding as I felt both warm and "airy"


my Alpkit Merino wool layer whist riding was really comfortable


Great quality, fit and features

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

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
