Just gonna start by recapping what Nick said, and they are 2 different jackets as the Proximity is insulated and the Stratus is not. Both are nice pieces. The Stratus is pretty versatile because it can cover a lot of temperature range depending on how you layer. The Proximity is pretty packable for a insulated jacket. It's not as heavy as the Solitude mentioned. This may come down to expected to outside temperature and how easily you get cold. If the majority of your hunting is in the 10-40° range then I'd go with the Proximity. If I could only purchase one coat, for stand hunting, I would start with something insulated such as the Proximity.
