In reply to alexgoodey:
My experience has been that the quality is hit or miss. Mostly miss.
Sometimes, the fabrics are not the same as the garments sold here. (Says Goretex or Schoeller, but isn't.)
Sometimes, the fabrics and construction seem great, but the zippers are crap. (fake YKK zippers that fail)
Sometimes, you get lucky, and get the genuine article. However, unless you can actually handle and see the stuff before you buy it, you are taking a gamble on quality if you buy from China.
