The Kepler Long Johns are the ideal addition to your cold weather layering system for winter walking epics, hunkering down on chairlifts or staving off sleeping bag shivers.

  • Ultrafine Merino wool has a high warmth-to-weight ratio
  • Corespun Merino fits better, keeps its shape and lasts longer
  • Breathable and wicking Merino wool keeps you comfortable

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.

Features

Key Features

  • High warmth to weight ratio of superfine merino and natural temperature regulation properties keep you warm in cold weather and cool when you heat up
  • Merino Core Spun with nylon and spandex improves fabric durability, recovery and stretch whilst retaining all the benefits of merino wool

  • Next-to-skin cut and low-profile flat-lock seams enable easy layering
  • 3 Year Alpine Bond
