Really? Show it off, lots of work to build it.
I aint big, but I like my arms out. Cant stand teh feel of sleeves, never had to wear 'em at jobsites whole life. That, and if ya aint got much size,,, Nobody has EVER tried to mess with me anywhere with my arms bare. Not that Im massive, its just clearly going to be a problem 4 them.
Thats important in a lot of places I been.
