MK3 Thermal Socks



Modeled after the socks used by the Military for diving in cold Arctic waters, the MK3 Thermal Socks are crafted with a multi-layer design.

  • Outer Nylon with heel stretch panels
  • Primaloft®
  • Inner Fleece

Features include:

  • Featuring a high loft, breathable, and insulating polypropylene Polar Fleece inner lining, these socks are designed to effectively wick away moisture for maximum comfort.
  • StormProof 70 denier micro-ripstop water-resistant Taslon outer nylon facing
  • Primaloft® sandwiched between fleece lining and nylon facing – Primaloft® is as warm as down, compressible, breathable and offers superior water repellency.
  • Complement this with the MK2 Undergarments, or layer with the MK1 undergarments for colder conditions.
  • These socks can be worn alone or paired with a thin moisture-wicking sock to reduce the frequency of laundering.
