Lycra has its place and we’d argue a good chamois pad is worth its weight in gold – or at least in sudacreme. But you don’t always want to look like Adam West’s incarnation of Batman when you’re away on a leisurely bike tour or heading to your local trail centre. That’s where the Kepler Padded Boxer+s come in: all day riding comfort hidden beneath café-acceptable clothing.

A dual density chamois pad contours to your body, cushioning your sit bones and protecting against saddle sores. The pad is treated with an antimicrobial finish which, combined with Merino’s natural odour-resistant properties, make the boxers an ideal under-short for multi-day bikepacks into the Scottish wilderness and sunbaked European bike tours.

Flat-lock seams and a high, wide waistband are fit neatly underneath outer shorts, and breathable, temperature-regulating wool keeps your nether regions dry and comfortable even when you’re grinding up a never-ending pass with a full load. We use exceptionally soft superfine (17.5 micron) merino from Australian non-mulesing farms – for happy bums and happy sheep.

We’re using Core Spun merino for our 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.


Key Features

  • Merino core spun with nylon and spandex improves fabric durability, recovery and stretch whilst retaining all the benefits of merino wool
  • Wool is highly breathable, naturally absorbing water vapour into the internal structure of the fibres before evaporating it, wicking away liquid sweat when necessary
  • Dual density chamois pad contours to the body and an antimicrobial finish helps to combat nasty saddle sores and odours
  • High, wide waistband, low-profile flat-lock seams and superfine merino are comfortable under layers
  • Wool is naturally odour resistant allowing you to wash it less frequently

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 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.
