The Catalyst jacket definitely shines as a spring/fall soft shell for active hunting situations or going to town. I would not rely on it in the tree stand as an insulating jacket. One other note is that I find the lower sleeves and cuffs to be very tight so if you would consider yourself to have larger forearms this may be an issue for you. Where the Uncomphagre shines is as a packable puffy insulation. I use it in the tree stand as my outer layer but it is not super quiet (I have the 1.0). If I did the majority of my hunting from the stand I would look to one of their other pieces in the whitetail line up. I do a little of everything so the Uncomphagre is versatile enough to get me by in the stand.I have been looking at the catalyst jacket and also the solitude jacket and uncompahgre. I'm in MN mostly a stand hunter. Any experience with the solitude? Don't know if the catalyst will cover me for the whole season or if I should look into getting both, or getting an Unc 2.0 instead of solitude. It's all intriguing but the budgets not going to allow me to buy them all.
