Layer up to stay warm, keep cool and otherwise ride all day in comfort with the Rapha Women’s Merino Base Layer in long or short sleeved options.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 Womens Base Layer has been cut specifically for a female shape, with a neat, set-in v-neck that has a finer binding than the mens version. Other features include set-in sleeves and flat lock stitching, designed to ensure the fabric wont chafe and to eliminate rubbing from bib shorts and bag straps.
