The Comp is thermal lined, a material like thermal underwear to retain body heat and keep you warmer in the water for longer. At this price it really is worth considering and you will not be disappointed.
Another big plus point is Xcel's consideration for the enviroment by using limestone neoprene & water based glue for the seams
