Just a little insight on Joe Rocket... back in 2002 (if I remember correctly) JR was still a very small Company and they were still making their product in house (read: in Canada) so the production and quality control was much better. When they decided to expand, they went the way others have and went to China or Taiwan and the quality suffered, hence, the problems with a lot of their product.
Being said that, they know this and they are probably willing to exchange the product, no questions asked, if the fault lies with them. This is also true with a lot of the Manufacturers that work out of China & Taiwan.
Well RC, you are right about manufacturing. It is now done in places like Taiwan, Phillipines, China, Pakistan, and Brazil. However, this is true of companies like Dainese, Alpinestar, and some other really top brand names. I will tell you this - at this age and time - worksmanship in a lot of this places is top notch, just by sheer repitition of work. Remember, it is not just suits - you have helmets and other such gear made in these places.
What becomes an issue is how much a manufacturer wants to spend (cost) on suits. You have about ten different grades of leather you can use. You can go from Cheap milled leather to premium milled leather and up to Naked Leather (Drum Dyed / Premium Leather). Then, you also have a choice on how you cut your suits, how leather might be wasted, and also the choice of thread. Then you get into how you stitch the suit and how you place the the armour. It is cheaper to insert the armour in loose pockets in the liner than it is to stitch it in place. Go look at a Dainese or Alpinestar vs. a JR, that is why Bock was saying the armour moved all over the place.
So... considering that Alpinestars make their suits in Asia, China, etc. They are still able to maintain quality by dint of design, craftsmen they choose and also final quality checks - anything less is really on the manufacturer.
