Manpacks is hilarious, super well done, and the undies are good too. I can't wait for them to start sending me shampoo, soap and all that stuff in my manpack. I hate shopping.
If manpacks added different colors of american apparel man-shirts (I like blue) and basic cargo man-shorts, I'd sign up today. In fact, I still might sign up today, but I'll have to go to K-Mart to get my reasonably priced man-shorts -- a trip I've been avoiding.
