About every third piece of cycling clothing I buy nowadays is made by the godless commie red Chinese. Quality seems to be very good to excellent. Buying direct from the mainland websites, buyers generally report reasonable service/delivery times and acceptable quality. Be prepared to give your purchased items away to friends/team mates if the fit is off...returns are usually a ***** and, of course, not cost effective.
Some folks do report the generic chamois are not up to snuff with name brand clothing, but I would say that is to be expected when purchasing a $15-$20 pair of shorts. Sizing can be funky and buying 'large' is better than buying too small IMO. At least you get something you can get into and use for training if for nothing else. Seams and sewing have been on par with what I get from Nashbar, Performance and other discount clothing sources.
The Chi-coms also manufacture excellent firearms. Their Tokarev, Simonov, Kalashnikov and Makarov clones are all top shelf.
