We use 100% genuine superfine non-mulesing merino wool to ensure our Kepler long-sleeved top deserves a place in everyones outdoor layering system.
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.

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

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.

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

It wicks effectively, it's good on its own, with a wind or waterproof, or as the basis for layers on really cold days.

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.

the best value top tested

The Alpkit Kepler (RRP £29) comes in both short- and long-sleeved versions and provides a toasty base for any layering system

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

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
