  • Warm! And soft!
Color: Gray Green-black Size: XX-Large
These fit great. The quality is excellent, much better than the standard very thin almost see-through thermals one is normally used to seeing. They have some weight to them, but only a little, some would argue they don't, but I think it's a good weight. Shows that they are made of good material. The functionality is awesome. The are well made, stitched well, there are patches on the arms and legs to improve maneuverability. Very soft, breathable, looks good, feels good. I am very happy with this item! ... show more

  • Soft and warm
Color: Mock-royal Blue Size: XX-Large
Ordered these for an outdoor event. They are so soft and warm. I ordered them a size bigger and they fit perfectly. I’m 6’4” and the top comes to waist line. Since they’re going to be warn under my clothes this isn’t a problem but tall guys be warned. I would definitely recommend them though.
