We ask our base layers to do two things: keep us dry and minimize abrasion from thicker outer garments. When worn under bib straps, a jersey, or a jacket, the Gore Bike Wear Short Sleeve Women's Base Layer delivers these benefits. And its reasonable price tag shows that Gore Bike Wear believes that adding some comfort to your rides shouldn't cost you your last penny. Sure, your jersey is made of sweat wicking fabrics, but that doesn't mean it won't get clammy on hot, humid days when you're really pushing your limits. The Short Sleeve Women's Base Layer is made of a thin and soft polypropyleneelastane blend that gives you added moisture management. Specifically, its push pull effect draws perspiration away from the skin and to the external layer of the fabric, where it can evaporate. You won't find many seams on this base layer, but the ones you will find are flat locked to minimize friction. The back is extra long to provide full coverage over your lumbar region, even when you're reaching for the drops. The Gore Bike Wear Short Sleeve Women's Base Layer is tight fitting and comes in sizes X Small through XX Large. It's available in Black or White.
