Hopefully I'm not in trouble for posting a link to a different vendor, but it's just a t-shirt!

Blipshift, if you're not familiar, is a t-shirt/accessory site, mostly geared to gear heads. Their designs only stay around for a little while, but sometimes make a guest re-appearance. Here's a chance to augment your wardrobe with more Viper stuff!!

IMHO their sizes run a bit small..
