#160- SEALSKINZ black waterproof neoprene athletic socks

hese are constructed with three layers. The outer layer is nylon and spandex (for a good fit and durability,) and the inner layer is a nice Coolmax yarn (which is surprisingly soft and comfy.) The middle layer is where the magic happens though – it’s called “Waterproof MVT,” where MVT stands for Moisture Vapor Transpiration, and it allows perspiration to escape but will not allow water to penetrate.
