people that have experience with both - which one is warmer?
I have the LPP, not the Chamberlain. I'd agree the Chamberlain is in a different class of warmth. I wouldn't swear to the accuracy of this chart, but it's what I saved when doing my homework on puffy jackets.
Warmest to least warm
Chamberlin (11oz of down)
Montbell Permafrost (9oz of down)
Sitka WS down (around 9oz of down synthetic mix)
Kuiu Superdown Pro (5oz of treated down)
Kifaru LPP (3.6oz synthetic)
