The Madison Isoler Merino Womens LS Base Layer is an excellent thermal layer, providing unrivalled moisture absorption. The 100% Merino wool is 190gram in weight, ideal for sports by keeping you warm on the cool days and quickly wicks the sweat away on the warmer days. Unlike man-made fibres, Merino wool retains its thermal properties when it's wet to better regulate the body's temperature. As Merino is a natural fibre it naturally wicks sweat away from the body and doesn't hold the odours that man-made fibres do, keeping you dryer and odour free for longer.
