The Men's NTS Mid 250 Crew is one of the warmest next-to-skin baselayers available from SmartWool. It has an excellent fit and the chafe-free seam construction and panels offer more comfort with a pack while a dropped rear hem provides excellent coverage.
SmartWool use high quality Merino wool in all of their products. This gives them the comfort, performance and durability that you need from your socks; which means you are free to enjoy the journey and move with luxurious comfort.
The great thing about Merino wool is that nature has given it all the qualities you want from an outdoor material. It’s both warm and breathable, giving it exceptional performance as well as being both hardwearing and yet incredibly soft against even the most sensitive skin.
