Is this bag old? I've had it for years, and I think it's from a pair of Sub-Zeroes I got back in 1994, as they're the only Oakley's I've had until this year. But I'm not 100% so was just wondering if anyone can tell if they're actually vintage. If so, are they collectible or valuable, or are there loads of them out there? I've seen some people say they prefer older bags to the newer ones, that they were better quality. Thanks.
