    Keep looking.

Don’t try and remove the massively large stiff tag on the inside of the back crack of the ass area or the material will separate. The stitching appears to run right through that tag. Remove it and the pants fall apart. Quickly. Can’t leave the tag there cause it’s so stiff it jabs you in the ass crack. Contacted the seller about this. They did not wish to participate in anything to make it right. So I’d say find another seller for your needs for this or anything else they may sell. Move on....

    True Polypropylene Warmth
  

*by U***T on Reviewed in the United States on January 21, 2019*

These fit like a pair of sweatpants under my jeans but they kept me truly warm. Fishing in the snowy Sierra Nevada Mountains wearing only my ECWCS polyprop’s under pair of jeans was enough to keep me warm and dry all day. I’d gotten the knees of my jeans wet while kneeling by a stream and I couldn’t feel wetness on my skin. These are way warmer than the tight dual layer fleece polyester ones I’d purchased earlier! Lesson learned! By the way these sizes are pretty similar to USA standard.

Fit was just right but I don’t think it’s an XL. Fits more like a large
