Review: worth the money - Nice and toasty, just a great design.
Review: zipper problems - Nice and warm at +23 degrees F and windy. The zipper was sticky and jammed the first trip. Brought it home and unstuck it with great force. The next trip I had the same zipper issues so I had to return it. Too bad, it's a really nice bag with plenty of room for me.
