Review on Thermal Underwear Fleece Extreme Winter by Chp Rodgers

I have ordered a men's set of thermal underwear, men's fleece briefs for extremely cold winters. I ordered a very large and it says x-large. But as soon as I put it on, it came up like a medium. The funny thing is I was actually tall but I said I'd go for the X-Large if it was a bit tight. The wrong xx was a better medium so I think I should have used xxxx-large. Also not really sure about the material, seems very cheap almost sure will shrink in the wash. IN ANY CASE, THIS ITEM DOES NOT COST $21.19.
