Winter walking epics, hunkering down on hoarfrost-ed chairlifts or staving off sleeping bag shivers: an extra layer of woolly warmth is the best defence for when the mercury plummets and the bitter wind bites.

The Kepler Long Johns are the ideal addition to your cold weather layering system. The superfine (17.5 micron) merino we use has an excellent warmth to weight ratio and, as an ‘active fibre’, responds to temperature changes to keep you warm in the cold and cool when you’re working hard.

Merino is also highly breathable, transporting your body’s moisture vapour outside without feeling wet to the touch. Whether you’re slogging up a Munro in knee-deep snow or standing around on the summit waiting for your pals, you’ll stay warm and dry. 

We’ve used Core Spun merino for underwear, a technology with all the benefits of merino but with added durability. It’s still merino on the outside but a nylon and spandex core produces a yarn that’s harder wearing and rebounds back into shape better than 100% merino. 

Wool is a naturally odour-resistant material, meaning you can go longer between wash cycles on multi-day trips – kinder on the planet and anyone you’re sharing a bothy with!

Flat-lock seams, a low-profile waistband and next-to-skin cut ensure the Long Johns layer neatly under your outer trousers and the superfine merino is soft against the skin. We also only use merino from Australian non-mulesing farms for happy legs and happy sheep.

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 at 30°C.

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 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.

Bex
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!

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"

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
