Review: Bad quality - Nothing to do with thermal
Review: Not a real thermalwear - Im in a 11 degree celcius weather, it doesnt keep me warm..Ive had thermals before and so I know what a real thermal wear is, and this aint it. its just a long shirt. The people on the other reviews saying this works are either lying or got another product than what I got.
