Mine is October Colorado but you get the gist, covers single digits to hot conditions, and I'm nearly an all FL guy. I really feel that this system covers me pretty well.
Top:
FL Wick 150 S/S - I have a L/S, S/S, and 1/4 Zip L/S, I'll probably be rocking the S/S as my base. But I run hot.
FL Kiln 250 Hoody - for when I get chilly, which will be rare when moving. I like the hood, and I'm by far not a hood guy.
FL Chamberlain - only for sitting still. IF forecast doesn't call for it to get below 35-40* at elevation, I'll probably bring Brooks instead.
FL Vapor Stormlight Rain Jacket - for when it might get wet or really windy.
Bottom:
Kuiu Zip-Off Merino 145 - Really wish FL would get on board here, I just can't get past the convenience of the Kuiu.
FL Corrugate Guides - Love the pockets and suspenders.
FL Uncompahgre Puffy Pants - see notes on Chamberlain above.
Kuiu Teton Rain Pants - they were cheap and light, only wear in extreme circumstances.
Head:
FL Aerowool Neck Gaiter - can pull it over back of head and face if needed.
FL Tundra Balaclava - awesome, awesome piece for when you feel all of your body heat leaking out of your dome.
FL Tag cuff beanie - for going over the cap when walking in the cold.
Hands:
FL Talus fingerless - the go to, the bomb diggity, surprisingly warm.
FL Talus full finger - so excited for these. My system now will be the fingerless normal, and if its extra cold the full finger on under the fingerless. If I need more warmth than that I'll make a fire or put my hands in my pockets.
Feet:
Injinji Liners - no blisters. I used to get them between my toes. These solve that.
FL Moutain Athlete Triad socks - best overall FL sock IMO.
