The quality production bags these days all seem to have quite a few more features than my 15 year old bag. It's been a good bag, but doesn't have a pillow pocket, for example, or a watch/jewelry pocket in the hood or a draft tube or a draft collar, all of which are nice developments. The one thing I haven't seen, however, and this is just a personal preference (something I would put in a bad if I was doing it myself) is an inside pocket about hip high where I could put my socks. Again, this is just me, but I normally crawl in with socks on and then pull them off sometime later. In the morning they're gone! Ok . . . hiding maybe. I assume they're still in the bag with me, but sometimes they're hard to find and always out of reach. And for sure they're never together. But if I had a little pocket within easy reach to put them in . . . well that would be great. It's the little things, you know.
Good luck with your bag. Hope you do well.
