Merino Base Layer
Any experienced cyclist knows the value of a good base layer. It will keep you cool on scorching hot cols in July and warm on freezing descents in January. A good base layer helps regulate body temperature whatever the weather, transfering moisture from the skin and proving a vital aid to performance.
Rapha base layers are made from 100% merino wool and are naturally anti-bacterial and odour resistant. Wicking moisture vapour extremely quickly, they are soft on the skin and itch free.
Rapha’s merino base layers come in three styles; sleeveless, short and long sleeve. All the seams have flatlock stitching so they won’t chafe and are positioned behind the shoulders to avoid bag or bib straps rubbing while cycling. The base layers are close fitting and cut long at the back for a better fit on the bike.
"Base layers are incredibly important in winter to help regulate the body's temperature, but they also keep the body dry without it getting too hot. Rapha's base layer does this superbly, something that the mention of wool might normally have you doubting.”
- Cycling Weekly
"There's a soft pliability to Rapha’s wool that makes it a joy to wear as a layer against the skin. The wicking… is outstanding. It's the best base layer I've ever worn [and] was equally pleasurable at both ends of the temperature spectrum."
- Competitive Cyclist
“I love these things… and if it's a little cold, you can find me wearing it even as casual kit! I even wore one last night to the Man United game…”

Sizing
Customers may wish to drop down a size to their regular jersey fit as the merino has good stretch and base layers work most effectively when a snug fit.
