We’ve used pure merino wool from non-mulesed sources and ultrafine fibres (17.2 microns). As well as being soft against the skin, these ultrafine fibres have an excellent warmth-to-weight ratio.

Merino wool is also naturally odour-resistant, so you can wear it day after day without stinking your mates out of the tent. For comfort under layers and rucksack straps, the Kepler has articulated sleeves with low-profile flat lock seams.

Care & Environmental Advice

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.

Environmental considerations

Non-Mulesed Merino
We only use merino from certified non-mulesed sources. Mulesing is a practice some farms use to guard against parasitic fly strike. We believe this practice is cruel and unnecessary and something that can be easily prevented by regular shearing.

Sustainable Materials
Merino wool is 100% natural, biodegradable and renewable (sheep produce new fleece and sheep produce new sheep... usually in spring... they gambol... you know all this...)

Close fitting designed to conform to your body shape. Slim and slightly contoured but not form fitting. A comfortable fit that's not too tight, nor too loose. A looser fit with a bit more space but not too baggy.

Second Summit Kepler Review

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.

Wild Running Top Men's 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
