Gear up for a day on the slopes with the Mons Royale Cascade Merino Flex 200 Long-Sleeve Top as layer number one. This midweight baselayer is an ideal top to have next to skin, with breathable and warm merino wool combined with stretchy synthetic fabric for a comfortable fit throughout the day. The crewneck design and slim fit make it easy to layer under a fleece or puffy jacket, and thumbholes keep your sleeves in place while you peel layers on and off.
