Neoprene:Channel Flex, now the premium neoprene in the Xcel range. It's light, less absorbant, and way more stretchy, with an impressively soft and supple feel. A real winner.
Lining:Radiant Rebound, also new to the range, keeps cold out and heat in.
Seams:Glued, blinstitched, and internally taped
Seal:Smoothskin seal, which is easily adjustable using the cinch mechanism.
