To be honest, I've already returned one set on my own dime. I ordered a 'test set' that they had in stock in the wrong colors. I knew they were wrong when I ordered them and I knew I'd have to pay for shipping to return them when they either fit or didn't fit (to get the right colors and/or sizes), but I only ordered these to get a correct size. The 'test' jacket I ordered was a 46. It fit a little bit baggy, but I have a 45" chest, so I wasn't sure whether to go with a 44 or a 46, since I was right in the middle of the two sizes. I called Aerostich and talked to them and they said they could send out another 44 for test fitting, but I'd have to wait for them to build it because they didn't have any in stock at the time (in any color). I hemmed and hawed for a little bit, and they then made the offer to make both a 44 and a 46 in the color I wanted and I could keep the one I wanted and return the other one and they would pay for shipping... The only catch was that I would have to pay for both of them and then get a full refund once I returned the one that didn't fit. It sucks to be charged an extra $450 (temporarily)... But this way I don't have to wait as long, I get to compare the two sizes side by side, and I save a few bucks in shipping in the long run. I'm not made of money, but this was worth it to me.
