I ordered the pull-over Nano Puff instead of the full-zip jacket version of this jacket because I liked that it came in a neutral tan color, whereas the jacket did not have any neutral options besides black. It was cheaper to boot.
This was a mistake, however, because I realized that this is lacking in a few areas. The full-zip version of this jacket is easier to get on/off, can vent better (since it can be fully unzipped) and has pockets to warm your hands. The pull-over can get a little hot and does not vent as well. It doesn't do very well by itself as a stowaway jacket because it does not have anywhere to warm your hands. The pullover jacket is nice, but fits a very small niche in my opinion.
