100% genuine New Zealand merino wool makes our Kepler short-sleeve top ideal for a smorgasboard of outdoor activities in the mountains this summer.

The lightweight baselayer top is a staple piece of most people's 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.

The benefits of MerinoMerino 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. When you are on a mission you don’t want to be changing your layers with every turn in the weather. When it is cold Merino keeps you warm by trapping small pockets of air within its fibres. When its warm the same fibres will help to whisk moisture away from your skin so it can evaporate back into the water cycle! If you have been trapped in your garment for several days the antibacterial properties of a chemical called lanolin will help you stop ponging. Merino baselayer won’t make you fitter, it won’t make you go faster, but it will help you feel more comfortable when you find yourself in uncomfortable circumstances. Looking after your lightweight merino baselayer The better you look after this merino baselayer the better it will look after you. Cleaning can be done in luke warm handwash (or gentle machine wash). Merino can and does develop holes the more adventures you go on, so darn these up as soon as you can, othersise they will get bigger and you’ll be needing a new one! Common causes include snagging, vigorous machine washing, putting your finger through them when pulliing them on and hungry moths.

Excellent quality merino, well-made, great fit

I bought this as part of the baselayer bundle (1 short, 1 long sleeve for £55) so it was even better value. Very impressed by the quality of the fabric, the stitching and the style. The aubergine colour is exactly that - aubergine - and the weight is light but not see-through. The sleeves on the short sleeve version are just above the elbow, which I like, and the neckline is perfect, not too low to be work as a top layer. I wore this on a warm and windy walk up Pen-y-ghent, under a windproof jacket which can get a bit sweaty. The baselayer was incredibly comfortable, not one itch from any part of it, and I finished the walk in as non-smelly condition as I started it. I'd be happy to take this on a 4 day trip as my only baselayer.

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

Kepler Merino

this base layer is astonishingly good value. It’s great on, light enough to stash in your pack just in case an extra layer is in order and nice enough to hang out in at the end of your ride

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

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.
