I admit I wasn't really familiar with Chipp before I picked these up thrifting today, but they looked great so I got them. Can anyone tell me tell me anything helpful about these pants? I was going to put them up on eBay because they are about a size or two too big for me both ways. Are they still in business, and, if not, when did they go out? Is it possible to tell from the tag, the zipper, belt loops, or other features to determine when they were made? Any help is much appreciated. Thanks!
