I don't have any real experience with them yet, but I just ordered the Catalyst pants. I really like the style and the material they used. I think they will be perfect for bow hunting from Sep to early Nov. Based off of their size chart I am a small so that's what I ordered. The inseam fits me perfectly, but they are too tight in the waist so I am returning them for mediums. I would suggest going a size up if you are in between two sizes for the pants.
I have the jacket and pants. Great system. Quiet as all get out which is great for tree stand hunting and plenty warm for early mornings and late evenings in early season. You will want something over it or heavy under layers under it for mid and late season.
I picked up the jacket this season and used it on a couple elk and deer hunts. I'm 5'8'' 185ish and the large fits well with a base layer and citrus puffy underneath. I found it to be very comfortable to wear to the point that I might pick a non-camo version to wear around town. As mentioned it is ultra quiet for a soft shell. It is fairly breathable and was able to cut the wind but did not block it completely. I have not tested in any kind of real precipitation but the DWR seems to be as expected, ie., will repel but not waterproof. The cut on the hood is very well thought out and does a great job of protecting your face when zipped up. My only gripe is with the athletic cut, the sleeves around the forearms are pretty snug and it would be hard with multiple layers or popeye arms to fit comfortably.
