The Madison Isoler Merino LS Baselayer is an ideal first layer, the Isoler Merino baselayer provides 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 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. The Merino hugs the body and stretches as you move making it the perfect fabric for a base layer. Worn by itself, over a jersey or under a jacket as a mid-layer, the Isoler merino base layer is perfect for cycling, skiing or hiking and everything in-between.Madison Isoler Merino LS Baselayer FeaturesThe all-over flat-lock stitching avoids any discomfortRound-neck collar for casual jersey lookReflective detailing for added visibilityIt might be wool, but its still machine washable
