NRS HydroSkin 0.5 legging in Dark Shadow. Midrise, quick dry, perfect for white water rafting. Runs smaller for a medium. 75% Neoprene, 25% Nylon, 0.5 is the thickness rating for the neoprene. Two small pills below the knees on the front and loose stitching at the ankle hems (which is a small manufacturer defect as they have been there since they were new), both pictured.
