  • Regulates Body Temperature:From the slopes to the chalet, the natural fibres of Merino wool are excellent when it comes to regulating your body temperature. The breathable material retains warmth, but not to the point of overheating - providing optimal comfort in any condition.
  • Ofter Than Cotton:This wool isn’t like your typical itchy sweater. We only use superfine (17.5 micron) Merino wool, resulting in a luxuriously silky soft, shirt that’s lighter and much softer than the average Merino or cotton shirt. It'll also maintain its form over time and not get ruined after a wash, like most clothes these days.
  • A Better Shirt Starts with Merino Wool:We bring the time-tested benefits of merino wool to everyday clothing. Wool allows us to make garments that you can wear more and wash less.
  • Lightest weight base layer ever:We've updated this 100% Merino wool fan favorite with new color options and an enhanced fit to improve functionality while elevating aesthetics. The addition of shoulder panels and its flatlock seam construction help prevent chafing and increase your comfort level. Add one of our best base layers for cold weather to your winter wardrobe and experience the difference the next time you go skiing, hiking, climbing, or biking.
  • Care for Merino Wool:Follow care instructions for individual garments. Through wash and wear testing, we develop our care instructions to keep our garments looking their best.
