Inov-8's Base Elite 125 crew neck top is made from superfine Merino wool (95%) blended with Lycra for a nice stretch fit.
Inov8 says: Boasting Merino wool, this is a fast-wicking, next-to-the-skin base layer that helps retain body warmth on long runs. A high cut neck ensures maximum protection from the elements. Long sleeves feature thumb loops. Tailored for women.
