Things are bit ass-backwards in this thread as of late... people are expecting elaborate design feedback from those with little to no design background whatsoever. Without knowing the background of the person providing said criticism, there's much speculation as to the validity of the feedback you are receiving. There are several apparel design sites and forums across the web with members seasoned in their respective fields and genres. You will gain and grow much more through obtaining their input than you would by kicking your ideas around in circles on HB.
Please do get serious feedback on both your designs and logos before throwing large amounts of money towards materials and printing. You'll save more money ensuring your foundation is solid before creating product than you would by printing runs of half-assed design and failed concepts. While there is a good number of well-executed products and ideas in this thread, there are even more god-awful attempts. Remember that it does cost money to make money. Hiring professionals with the technical ability to successfully mold your brand can very well be a necessary expense, one that stands to be recouped many times over through retailing a cohesive line of quality product.
