Purchased for early to mid archery whitetail hunting in the Midwest. Out of the box I noted this is an excellent product. Fit is perfect. Pattern is perfect. Functional location of all pockets are well thought out. Zippers are heavy duty but also quit and easy to use with lightweight gloves. The length of the jacket is slightly long and pairs perfect with the above waist fit of pants making it a perfect combo for sitting in a tree stand. No cold breeze up the back on this combo. I normally wear XL purchased XL. With a Merino under layer this is a great and functional set.

Just purchased for chasing Midwest Whitetail, surprised at the warmth it provides with a fairly lightweight feel. If you like to be mobile and end up back in a stand, this would be a great addition. I am typically a L and purchased L here, fits great. Hooked on First Lite moving forward, very impressed.

I purchased the Catalysyt set recently, both pants and jacket, mainly for spot and stalk in the northern Midwest. This system is perfect for moving and keeping you warm without sweating. Best Middle weight gear I’ve ever owned. I used this to hunt Whitetails in Missouri at about 40F in a stand with hard, gusty winds and moderate rain. I never felt the wind and the rain never soaked through with minimal thermals. Keep in mind it’s not exactly designed for stand hunting so using a harness will restrict your ability to use the pockets of the Jacket. Absolutely versatile gear. True to size, product description 100% accurate. I’ll buy nothing but First Lite in the future.

I’ve only used this on a few hunts but love it so far. I paired it with the ridge line pullover and was perfect for the 40 mph wind of eastern MT. The fleece interior is very nice and feels like a well made jacket

I purchased the Soft Shell Jacket, Vest & Pants. Right out of the box the gear fits perfectly. I went Large Vest, Large Pants & XL on the jacket. It is quiet, and will be perfect for those 40-65 degree temps in early white tail and spring turkey here in Oklahoma. I have had it out in the field twice, it is the best quality hunting clothing to date that I have purchased. Can't wait to buy more! I also want to say that I spoke with FL customer service a few times, got right to a live rep and everybody there was so helpful. This is the kind of thing that is really lacking today with most retailers, The customer service sealed the deal for me on FL. Just overall the best experience I could as for!

I normally wear everything FL in size medium. 33-34" waist, but broad shoulders and chest 42-44" athletic build. This was the first set I've returned and re-ordered a large. I could wear medium but would have been really tight getting a layer or two underneath when the weather turned colder. The mediums 'fit perfect' but not for layering. The large jacket and pants came back in today and fit much better. Can still wear alone down to mid 40s it seems or layer up to stay longer in colder temps. I think going larger allows greater versatility to layer and wear later into the year. Very quiet material and super comfortable.

So far I've been able to get two or three hunts out of this jacket. The first one was in temperatures around 5-10 degrees C. (Canadian) or 40-50 degrees F (freedom eagle). It was also raining with no wind. After about an hour of sitting still, I was certainly on the wet side of damp however, I wasn't cold yet. I would almost say comfortably cool. After another hour and a half I was so I was annoyingly cool. About a half hour after that I started walking around because I was waterlogged and cold. As soon as I started moving again, I warmed right back up, despite being properly wet. The second hunt it was about -5 C and I had a snugpak puffy underneath the catalyst, and while I was moving it was too warm, but when I stopped and the predawn winds kicked up, it was about perfect. I'm 183cm tall, have a 112cm chest and the large fits spaciously with a t-shirt, comfortable with a hoodie and puffy underneath.

This jacket is a perfect combo of warm and light-weight. I wish the pockets were insulated and that there was a slot for my harness lanyard on the back, but other than that, I couldn't be happier. I'm a weird size as a smaller guy with a more athletic build, so the Medium is just the slightest bit long in the sleeves, but the shoulders are perfect and I can draw my bow with no noise or issue.

I recently tested out my Catalyst Jacket/Pants combo and could not be more impressed. The soft shell exterior is extremely quiet while the 37.5 fleece is warm yet breathable. I live in the southeast where whitetail stand hunting is the commonplace - this kit paired with the Aerowool layers will be my staple for the mid season temperatures. Lastly, the Large jacket and Medium pant were a perfect fit for my frame (5'11" - 175lbs). This is a great company with a great product.

I've worn my catalyst jacket and pants on early and mid-season whitetail hunts in Oklahoma and Texas and on elk hunts in Colorado. Depending on how you layer underneath the jacket, it is good for high output hunts as well as sitting in a tree stand. It has worn well, hiking through waist high grass and sage. The fit is consistent with sizes I normally wear and is very comfortable. I went with a L pant and XL jacket. It is one of my favorite kits.
