ZhikSkin MicroFleece is relatively thin super stretchy neoprene, laminated with a very fine inner layer of silver fleece. This material combines to bring you a suit that is as warm as your traditional 2 or 3mm neoprene, however the suit is ultra-light.
Like all Zhik suits, the seat area has a special stretch abrasion resistant nylon material. Draw string waist keeps it all in check.
