here is a part of an email I just got from Chuck.

as for the dryer, I've washed several sets in hot water/warm rinse and then thrown them in the dryer at hot heat at least 6 times with absolutely no adverse effects on the fabric, but normal washings are supposed to be cold water wash and hang dry, with is the safest bet for long lasting care. If it doesn't hold up, we'll give you a new one, so give it a try, Russell.
