Really like the Chugach for rocky Mountains. Great weight to performance.
I have not been impressed with the Yukon. I have only wore it a handful of times working in the rain on my property and it has wetted out 3 times in mild rain after 2 hours. Maybe I got a dud, but have zero confidence in the jacket.
Gonna check out the arcteryx and kryptek mentioned above.
I have the kryptek takur jacket and lived in it for almost 2 weeks on a sheep hunt when it rained the first 8 days, along with many other hunts. It's phenomenal. I'm a huge fan of Schoeller and they're one of the only companies using it. I'll own the pants as well when I can afford them!
It's quieter than most rain jackets and very comfortable. Well designed.
