The Men's NTS Microweight Bottom is SmartWool's lightest weight baselayer, perfect for high-intensity tours and sunny resort days. Merino wool is highly breathable and regulates temperature to keep you comfortable, and it has natural odor-resistant properties so you don't stink up the car after a long backcountry tour. Flatlock seams won't chafe, and the terry loop-lined waistband feels soft against your skin.

Great gift!

  • Familiarity:I gave it as a gift but have feedback to share
  • Fit:True to size

Gifted these to my step dad for his birthday. He works outside in the winter and gets cold fairly easily. These are perfect for him to layer underneath his work pants to stay warm. He loves how lightweight these are and that they are wool and still keep him super warm. He's already asked me to send him another pair!
