What is neoprene anyway?
It's a synthetic rubber. In its non-foam form is very elastic and as a foam laminated onto knit jersey offers good insulation. The laminated neoprene is usually the one used by the apparel industry and comes in various thicknesses: 1.5, 3 and 6 mm being the most common especially in sports gear like diving dry and wet suits. Because my fiancé owns a couple of said suits I got to study the fabric and figured it should be interesting enough...
