More of a flash guard then a rash guard
I contacted a company that made digitally printed suits for track & field and cross country skiing. I had to modify their design slightly to fit our purpose, they became really nice! Since they print before they sew, it’s kind of tricky to make the same print look good in a small, and in an XL. We only made 15 pieces, so they became quite pricy. But looking this good can not have a high enough price tag!
