Purchased this piece for a week-long mule deer hunt in ID, but have worn this whitetail hunting in the east as well. It's a snug fit in the arms, so guys with large biceps may have to size up, but I was still able to layer underneath with a Klamath and Kiln. One positive to FL gear, is the arms are actually long enough. I've got a 6ft+ wingspan and all the pieces work well for me.

It's warm, quiet, and holds up to some moisture, but will eventually soak through. Great all around piece.

Have yet to test it in the field but wanted to post my initial reaction.

Positive:
The fit was overall great. I'm 6' and 190lbs, on the skinnier side and bought the Large. It's roomy enough to put some base layers underneath, which is perfect because I plan on wearing this through December into late Jan when temps get pretty low here. The material is QUIET, can't hear a damn thing when you are wearing this. I tried it on in my house for like 10 minutes, temp at 70° and I was sweating, so I have no doubt this is going to be a critical piece of gear when I start getting it outside. Surprisingly lightweight, and thinner than you would expect, but it's technical gear so that is to be expected. Excellent movement around arms. Draw your bow and the jacket doesn't move, it's perfect.

Negatives:
While the fit was overall great, it is a little roomier in the stomach area, but not a huge deal because it does have drawstring adjustments at the bottom, HOWEVER, careful which way you're pulling on these. My one side broke the little stopper behind the pocket and there's no way to get it back on. I tied a knot in it instead, not gonna worry about it, minor but still.

Overall, can't wait to put this thing to the test. Will maybe post a later review once the season is done.

I'm 5'11, 185, fit was great, snug around arms and moved well. Fabric is strong and flexible, well made. Functional pocket locations. Loose enough you can wear a thermal base layer underneath without being tight. Highly recommend. The jacket very comparable to other upper end hunting/outdoors softshell jackets.

The Catalyst is not only a necessary piece of outdoor gear, it's also an awesome jacket for daily life when it's a bit cooler out. It fits and looks great all while keeping you warm.

Was looking to replace my browning hell's canyon. Ther catalyst ran to small for me. I'm 5'8" 185 lbs fit person and the large jacket and pants were too tight. Also I did not like how thin the products are. Need something a bit more substantial for stand hunting Michigan's October. I sent it bank and got another season with my brownings
