Over the last few weeks I've gone through the websites of each of the manufacturers that appear on the various gear lists and have updated all of their products, adding whatever is new, removing whatever isn't made anymore, fixing broken links, updating weights from redesigns, etc... There's still a bit of work to be done on the lists, but they should be a lot more comprehensive now.
I've also added quite a few manufacturers that readers have emailed me about. Hopefully I got them all, but if I missed something, definitely send me an email and let me know! People have emailed me about a lot of foreign manufacturers, and those seem to mostly be the ones that I'm missing at this point, mainly because we just don't hear about them much over here in North America. So if I'm missing a good outdoor gear manufacturer from your country, send me an email, and I'll absolutely add them.
As for the lists, there were 1588 pieces of gear spread out throughout the lists, and that's up to 2205 now. Most of that was in the sleeping bags, tents and backpacks lists, but every list got at least one new item.
