I'm with @Tam... I like the first "VT" logo, not the distressed one, too... they'll be "distressed" after a couple years wearing it anyway .
The large logo on the front is good, but perhaps also offer one with a smaller logo on the left breast and the "Vapor Talk" logo (3rd image) on the back?
The gals like their totes... and guys like their hats (I'd love a hat with Velcro adjustment or "one-size S/M, L/XL" solid back). Other good swag might be water bottles, battery cases (the zippered ones like eFest), and vinyl stickers (like window stickers for the car) ?
