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 Batman, head to toe in lycra. The Kepler Padded Boxers provide all day riding comfort beneath café-acceptable clothing!

  • Dual density anti-microbial chamois pad
  • Odour-resistant, breathable merino
  • Merino corespun for a better fit and durability

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.

We’re using corespun 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
  • 3 Year Alpine Bond

Sustainability and Product Care

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.

We have dedicated Repair Stations in our stores and we're fully equipped to breathe new life into your old kit. This includes spare parts, patches, new zips and wash and reproofing of your down and waterproofs. Pop into any store or contact us online for more info.

Alpine Bond
If one of our products does not meet your expectations upon delivery, or if during its lifetime does not live up to the demands placed upon it, please return it to us for repair, replacement or refund. If the problem is our fault then we will do this to your satisfaction. If it’s your fault then we will help out the best we can. Find out more about our Alpine Bond here.


How It Is Made

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.

Natural Fibre 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...)

Where It Is Made
Our products are made in the best factories in the world. We know the factories personally and they have all signed up to our Code of Ethics in our supply chain. This includes the Ethical Trading Initiative base code, fair pay, safe working environments, no child labour, no modern slavery, no bribery or corruption, no materials from conflict zones and humane farming methods.

All our factories sign up to our Code of Conduct. Find out where we make our product by visiting our Factories of Alpkit factory zone.

Reducing our carbon footprint
We are carbon neutral under PAS2060 and offset our Scope 1, Scope 2 and Scope 3 operations and transport emissions. We recognise that offsetting is not part of the solution but a point to pass through on a journey to Net Zero. Carbon Neutral is just a step in that journey.

We have joined the Science Based Targets Initiative which sets independent targets for us to achieve to do our bit to limit global warming to 1.5°C. Our targets are to halve our Scope 1 and Scope 2 emissions by 2025 based on 2018 base year and reduce our total carbon intesnity by 15% every year to achieve genuine net zero by 2050.

End of life
When your partnership with this product is over send it back to us and we will pass it on to someone that needs it through our Continuum Project.
