As for the musty smell, that's a problem I personally face and I've validated that problem with a lot of my friends, peers, and customers. It doesn't happen on cotton but it happens mostly on the 100% polyester athletic clothing (which is the majority of all sportswear).
You're right though. Not everyone has this problem and maybe wrong detergent choice or washing habits play a part in that phenomenon. We just wanted to make sure we have the best anti-odor performance and the silver technology is the best in the industry. If you end up getting a shirt from us though, what you'll find to be the best feature is the feel and performance of the material we developed with the anti-stink part being the cherry on the top. That has been the case with 100% of our users so far.
