Description

Build your hiking or running base layer from the bottom up with the Kepler Boxers – breathable, wicking and odour-resistant Merino undercrackers.

  • Corespun Merino fits better, keeps its shape and lasts longer
  • Breathable and wicking Merino wool keeps you comfortable
  • Naturally odour resistant for wearing more and washing less

The Kepler Boxers are made from corespun Merino wool for extra durability and comfort. Corespun Merino is made by wrapping a nylon and spandex thread with Merino fibres. This clever corespun fabric has all the benefits of standard Merino, but gives your boxers a better fit, helps them to keep their shape and extends their life. We only use super soft ultrafine Merino wool (17.5 microns) from certified non-mulesing farms.

There's no point covering yourself in technical outdoor gear if your cotton undies are going to get all damp and clammy. Merino wool is highly breathable, transporting your body’s moisture away from the skin to keep your nether regions comfortable underneath your walking trousers or running tights.

As an ‘active fibre’, Merino responds to temperature changes too. It controls the rate of evaporation to keep your bottom toasty in winter and cool in the height of summer. The Kepler Boxers use an active cut with flat-lock seams and a high, low-profile waistband to fit comfortably underneath various layers.

Merino wool is also naturally odour resistant. This means you get more uses out of your pants before consigning them to the wash bin. It also makes them ideal for multi-day backpacking trips - kinder on the planet and anyone you’re sharing a tent with!

Sustainability & Care

Product Care Information

The better you look after this Merino garment, the better it will look after you. Give your Kepler Boxers a long, happy life with these tips: Hand wash your boxers 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.

Sustainability

We only use merino wool from certified non-mulesing sources. Mulesing is a practice some sheerp farms use to guard against parasitic fly strike. We believe this practice is cruel and unnecessary and something that can be easily prevented by other methods.

Kepler Merino Review in Velome

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

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
