Whether you're looking for a base layer to go under your waders or ski pants, Smartwool has you covered with their merino wool. I've been wearing Smartwool almost as long as they've been around and I can assure you they deliver a quality product that will last you years. I almost never wear a mid layer thanks to the thermal retention on these bad boys. You're toes will thank you for supplying them with ample warmth and circulation.

  • Great for snowboarding, fishing, or any other cold weather activity
  • packs well and can be worn multiple times before washing
  • super warm but still breathes well
  • can be too warm at times
  • merino can be itchy at first
