Inspired by the Canadian Military who regularly dive in Arctic waters, the MK3 sock has the same tri-layered system as our popular MK3 Undergarment:
1. Outer Nylon (with heel stretch panels)
3. Inner Fleece
- Our Most extreme cold water sock available
- Breathable, moisture-wicking, high loft, insulating polypropylene Polar Fleece inner lining
- Storm Proof 70 denier micro-ripstop water-resistant Taslon outer nylon facing
- Primaloft® sandwiched between fleece lining and nylon facing
- Sole and heal are reinforced with a heavier nylon for durability.
- Complement this with the MK2 or Thermal Fusion Undergarments.
- Sock can be worn alone or with a very light polyester sock to minimize laundering.
