Product Description

We can officially only rate these warmers at UPF 50+, but in our laboratory tests they actually blocked 99.8 percent of damaging UV rays. We used a polyester base that is not only more effective than nylon at blocking UV rays but is also much better at keeping you dry, which means these skins are better in both cooler and warmer conditions. We’ve kept the construction very clean to eliminate seams that can rub, and we used our double-sided silicone elastic to make sure they stay in place. They fold up extremely small, so they’re great to stick in your pockets for your next big mountain day.


  • Solare fabric keeps the chill off without causing overheating
  • UPF 50+ protection
  • Polyester based for excellent moisture management
  • Double-side silicone elastic at top for excellent grip

Base Layer Guide

What is a base layer?

 A base layer is the top you wear next to your skin and under everything else while cycling. It’s soft, absorbent and wicks away sweat.

Who needs a base layer?

Anyone cycling for any distance or length of time will really benefit from the extra comfort of a base layer.

What are the choices?

You can opt for a long sleeve base layer in winter or a short sleeve one in warmer weather. Most are made from fast-wicking polyester, but there are also some in warm, soft merino wool or anti-bacterial bamboo.

What should I buy with it?

A base layer is your first line of defence in a layered clothing system, so it’s best with a jersey as a mid-layer then a windproof or waterproof outer shell for full weather protection.

Anything else?

Base layers are simple and essential, but you can get some really technical options too. There are some with silver woven in to make them more resistant to odour and compression base layers which are said to help muscle recovery.

See our Layering for cyclists guide for more.
