Purchased the Catalyst system for a late season Wyoming Whitetail hunt. I layer with the Kiln Hoody as my base, followed by the Furnace Quarter Zip, then the Catalyst Jacket and Pants. I wear a size medium (32" waist, 41" chest), and all the layers lay nicely without bunching. The athletic cut is perfect for my build, as I do not like baggy items when hunting, bow hunting. I do not suspect that I will have any issues keeping warm with the layers I currently run. I like the cuffs on the Catalyst Jacket, the hood has a nice cut to it, functional pockets, and this gear is QUIET!

Solidly built, highly functional pockets and hood coverage is great. Has great water wicking properties. Very warm given it's light weight. I have wore a Kiln underneath and has kept me plenty warm in low 40's temps. The only constructive criticism is I feel it could be a little tighter through the stomach/waist area. Although that space does provide room for a couple base/mid layers. Overall, fantastic do it all jacket.

The Catalyst is hands down the best jacket I've owned. Been using it to scout elk on cool mornings. Quiet soft and warm, Layer up with this and it will work well into winter.

So I have the sawtooth that has been phenomenal . I am headed to Oregon In late Oct to hunt elk and wanted an alternative just in case we hit some precipitation. Selected the solid grey after
Deep diving into what colors big game truly see . With my pack,sling, and bono harness , I am confident that I will be breaking up the monotone.
The jacket quality is fantastic l. When I mean quiet , it’s silent . I am 6 foot 3 225 lbs and I was concerned with the fit .... not to worry the xl is perfect . The sleeves are nice and long and very secure at the wrist .... Plenty of articulations draw , low crawl , etc. th inside is very soft with high quality materials . The hood give excellent peripheral view . Having the sawtooth and this jaket give me a great range of flexibility for all of the unknowns

For a long time I have been searching for a jacket that could provide a small amount of warmth, water repellency and wind reduction as well as being incredibly QUIET! First Lite hit the nail on the head with this one. I am primarily a bow hunter and this jacket is quiet enough to draw your bow without making hardly any noise at all. This is extremely important on quiet nights and mornings when you have an animal in bow range. Despite being deadly quiet, the jacket has had no problem cutting light winds and shedding light rain, all the while being very breathable. I am able to wear this jacket comfortably from spring bear, early whitetail and elk season, and layer it up into moose and late October deer season. This jacket is extremely comfortable, versatile and quiet and is a must have in any avid hunters arsenal.
