those seem oddly similar to Line's "I am a skier" t's
That normally wouldn't bug me much but Line also has "Ski and Destroy" shirts... I'm no lawyer but i'm not sure you can just make a shirt that says the same exact thing another company's shirts already say. Even if you legally can, something more original would probably prove to be a more successful option. Unless, of course, those were made first and Line is copying you... but i'm guessing thats not the case.
