Review on Terramar Thermasilk Filament Black X Large by Eric Grayson

I bought this in December to wear while riding my motorcycle. It wasn't until April that I had the chance to wear them. I didn't notice any increase in body heat retention. They are very slippery and you can see through them. Unfortunately, I did not try them within the given return period. I will look for another product that offers some form of insulation.
