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.
