Replying to Voleurz shirts

So i just got 3 Voleurz shirts during the NS Store specials and i love 'em; super comfy and tall as fuck. But yesterday i was playfighting with mah bros and i ripped my favorite (pinstripe). now, i know what you must be thinking; ''You cretin, what were you doing playfighting with an expensive and steezy tee?'' and the answer is i dont know, i had temporary brain retard but consider this: what ripped it is my friends pudgy fingers. Is this normal? Are those tees supposed to be resistent? and most of all, Is there a warranty? I'd like to know if reparing it goes well too because the fabric seems a bit stretchy and i dont know if it'll work well.
