Headed to Northern Tier? When it comes to bringing your personal and crew items, if you don't pay attention to how large / bulky some items are, you may find out the hard way, that packing is a volume problem.
Can you bring a lightweight fleece in place of a puffy jacket? Northern Tier allows for this but I wanted feedback from someone who has been there and has personal experience.
As long as it of synthetic insulation that doesn't loose it's insulative properties when wet. So it is "warm" when wet. The lowest overnight low temp will probably will be in the 40s. It can snow in the earlier months. So whatever will keep you warm, but is also highly compressible, works.
