I have two major complaints about many “cause” related T-Shirt companies, 1. they think that the cause is enough, and design is secondary, not true, if your trying to persuade anyone of anything design should be you number 1 consideration and it is worth investing in, hire a professional designer. and 2. they are ambiguous about how much they are contributing to the cause, with statements like “a portion of the proceeds”, or “10% of profits”, when we all know profit is a fictional number made up by accountants.
Five Humans on the other hand uses great design and donates 10% of the purchase price to the causes. Way to go guys, I really like the stuff. Not only that they are running a 15% off sale from September 5th to the 14th so check them out.
