This is an Under Armour blue long-sleeved shirt. It's a tight-fitting one. When I wear it in the winter to exercise, I don't feel the cold. I bought it in Canada about 9 years ago. The size is a comfortable fit for me, who is 177cm tall and weighs 75kg. I've used it several times, and there are no noticeable stains, but there is some wear around the neckline. Thank you for looking.
