I ordered 3 XL shirts and all 3 looked and felt like XXL's. I washed and dried them on HOT and they are all now the appropriate size. Only worn them a handful of times but no complains other than the original size.
My husband is a large man and always has trouble finding shirts long enough in the sleeve for him. These ones fit him great and the extra length in the body makes a great fit for him. They wear very well and he is very pleased with them.
