Looking at getting the kuiu ultra down jacket or the stone glacial Grumman down. Who has used both, which one is warmer

 

[NoWiser]

If you want warmth, get a Montbell Alpine or Feathered Friends Helios.

Ultra is 2.3oz down and SG is 5.4 oz down so obviously SG is gonna be significantly warmer
Kuiu Super down pro is 5oz down

I have the Grumman, it’s an awesome super warm, extremely light jacket. Only thing I wish it had is a waist cinch for keeping out drafts, other than that zero complaints I love it. Warmth to weight is as good or better than almost anything on the market even outside the hunting space

All I can tell ya is that I wore my Kuiu Ultra down Pro jacket on my late January predator hunt above the Arctic circle in Alaska and I was never cold. I wore a light merino base under a heavy merino base and then a grid fleece under my down jacket. It was -20° to -30°. I kinda feel like ANY of the brands mentioned will be fine and people quibble about one versus another. It’s all about proper layering for the immediate conditions. A 5 day hunt may require 5 different adjustments. For sure the Kuiu ultra pro ought to be adequate for just about anything if it’ll keep a thinner diabetic warm in those temps while sitting still for long periods of time. Just a thought.
