When the water temperatures demand a little more warmth, look to the NRS HydroSkin® 1.5 Socks. Same great protection-without-the-bulk as the tried-and-true HydroSkin 0.5 Wetsock, with three times the insulation.
The 1.5 mm neoprene core insulates and protects.
4-way-stretch PowerSpan™ outer layer gives you enhanced mobility and greater durability.
