ZhikSkin Microfleece is relatively thin (1mm) 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 these pants are ultra-light. Long pants offer the full protection you need to throw yourself around some more. Reinforced with durable ZhikTex in the knees and butt give the abrasion resistance where needed. Combine beautifully with many styles of Zhik tops. For example, the ZhikSkin Spandex top in summer, or the Titanium and Hydrophobic Spandex-fleece combination when it gets cooler.
