Husband loves it
Size: XX-Large, Color: Army Green
Gave this to my husband as a christmas gift and he really likes it. He says the outfit is really soft, it fits well, and the material seems to be of decent quality. Personally I think the color looks amazing, the material is super soft and not too thick and not too thin.
