This season I've used the first lite catalyst bibs paired with the black ovis anchor point down pants. I've absolutely loved this system. Generally I will wear my base layers and the bibs in then put the down pants on at the tree. The down pants unzip fully so that I can put them on under the bibs without take the bibs off- I just unzip the bibs all the way up to my hips and slide the pants under.
By just wearing the uninsulated bibs in I rarely over heat, especially since they have 2 way zips allowing me to dump heat as necessary. They also silence the down pants and help cut the wind quite well.
The down pants are super light and packable and incredibly warm. They are 120 grams of 800 full power down if I remember right. They can generally be bought on sale for $150 or so. Much warmer than the first light Uncompagrhe pants and cut the wind better due to the welded seams on the black ovis pants.
System is highly versatile. Listed below are actual temps from the season - all sits were a minimum of 5 hours on stand. All sits included the bib pants combo, I just noted what the rest of my lower body layering system was to illustrate how I make it fit the whole season:
30 - 45 degrees: first lite Kiln long johns
20 ‐ 30 degrees: first light furnace long johns
10 ‐ 20 degrees: first light fuse long johns and furnace long johns
Single digits and below zero: furnace, Kiln and fuse
When temps are above 45 i generally don't take the down pants, the bibs and long johns get me through
If you are not familiar with first lite, the fuse layers are 200 grams, 67% wool. The Kiln is 259 grams and the furnace is 350 grams, both layers are 95% wool.
