I wrote all this in another thread, I’ll paste it here;
I’m just here to chime in I’m on my first year with all this FL gear and I thought I’d share my experiences so far. First, I agree with everyone the quality is top notch. I’ve never owned any Sitka gear but this stuff is light years ahead of my old UA gear. All I’ll add about sizing is I wear the same size FL as I do everywhere else and followed their size chart have had no problems.
60 degrees or more and I’ve been wearing the Obsidian pants and the Wick crew. Add in the kiln for the very lower end of this range in a stationary setting. Only issue was getting into some burrs, but I’d say these pieces really regulate your temperature well.
When it’s been say, 30-60 degrees I’ve mixed in the catalyst set and been happy with it. I’ve never owned anything with a wind proof membrane so I don’t have a reference but the catalyst cuts the wind far better than my old UA Ayton jacket.
I had shared the concerns above that the Catalyst pants was going to be too light to get me all the way to my sanctuary bibs, but I was comfortable down to ~32 degrees with a 230g Minus 33 base layer under them. I did get some military ECWS grid fleece bottoms for a little more flexibility in my system (haven’t worn them yet) but if you’re not SUPER sensitive to cold, I think you could wear a mid weight base layer under the catalyst pants close to 30 degrees before you were uncomfortable. Your experience may vary.
We got hit with an early frost. That day I was worried I’d be cold, so I layered pretty heavily. I wore the 150g wick crew (I’ve been wearing that under everything), minus 33 midweight 230g top, the Kalamth QZ and the Sawtooth vest and had no problems. I took the Catalyst jacket but never put it on. On a few other days I wore the same base layers and was comfortable with the catalyst jacket instead of the sawtooth vest. I’ll probably reach for the Woodbury jacket instead, but I think if I wore the heavyweight furnace top, the Klamath fleece, and maybe the sawtooth vest underneath it, I could wear the catalyst jacket in the 20s and be ok.
I haven’t gotten to wear the Sanctuary bibs and Woodbury jacket but I’m very excited to try them. They’re very comfortable and quiet, but no field testing yet.
