Great work, for some unknown reason I cannot bear wearing non-cotton shirt and cloth, but cotton based clothing is far from durable. The best cotton shirt that I ever had until now (in terms of wearability and durability) is a mecerized golf cotton shirt by PGA Tour (casual wear not for golfing) but now I cannot find any golf shirt (PT included) with the same material anymore. As far as I'm concerned you have got a winner there mate if your cotton shirt is as good if not better than the PT shirt, hopefully your clothing materials will be available globally off-the-shelf.

Do you mind explaining your sentence here?
