There is no perfect jacket for all conditions.
For stationary hunting, Arctic Shield has proven it's worth to me more than once. Worn the jacket and pants many times, with and without a base layer, in 0-30 degrees with zero issues. The real test was a late season cow elk hunt where it was cold to begin with and the temps dropped. Nothing like -12 F with 35+ sustained winds to test gear; this is in the open without ground blinds. I was wearing a base layer. However, I'd never wear it if there is any kind of sustained movement. You 'll be covered in sweat in no time. Never pass gas in the pants; it just stews.
I'd never choose clothing that is designed for active hunting for sitting in a ground blind in sub-zero weather. You'll freeze your behind off.
Match the clothing to the hunt.
