Amazing thermal layer with microfleece inside, something I only found in Cold Gear Under Armor until now! It simply has a snug fit and not compression! If you want it as a base layer, go one size smaller for a fitted and slightly tight feel on the body, and two sizes smaller for a good tightness on the body. For example, in Under Armor compression, I wear medium which is quite tight on the body; the corresponding medium from Pentagon is just fitted, it doesn't compress.

Very good quality, it is for very cold weather because it has micro fleece inside so it is not suitable for mild weather!!
