Merino or Synthetic? With Smartwool Thermal Midlayer (TML) you get the best of both worlds. These unique midweight pieces have Merino inside to deliver all the benefits you know and love, with a Nylon outer that improves versatility and durability.
Smartwool socks and base layers are made from soft New Zealand Merino wool, which provides breathability and temperature control, keeping you warm when it’s cold and cool when it’s warm. Keeping your body dry means they also prevent odour build-up. Meanwhile, the tough Nylon face adds wind resistance to create a truly technical insulator. Try Smartwool TML and experience the ideal second layer for warmth without bulk.
