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.
