A supremely comfortable base layer made from highly-breathable merino. Wicks moisture superbly and is naturally odour resistant.Rapha base layers are made from the highest grade of New Zealand merino wool. The fabric is extremely comfortable, wicks moisture superbly and is naturally breathable and odour resistant. The Women’s Base Layer has been cut specifically for a female shape, with a neat, set-in v-neck that has a finer binding than the men’s version. Other features include set-in sleeves and flat lock stitching, designed to ensure the fabric won’t chafe and to eliminate rubbing from bib shorts and bag straps.
