NRS HydroSkin Short
Here's what other sites are saying:
For everyone from paddlers to surfers, Hydroskin is the perfect solution for the "in between" days when a full wet suit would be too warm, but you need some extra protection from wind, spray and cold water. Lightweight .5 mm neoprene insulates you from cool air and water and stretches for complete freedom of movement. Polyester ThermalPlush fleece lining feels good against your skin so you stay comfortable on longer paddling trips. 5" inseam. Imported.
