I ordered one from the outlet so I haven’t used it yet obviously, but I grabbed it for my elk hunt this fall. I’m 6’, 160, 40” chest, and got the large, I’m a medium more often than not. The sleeves and torso length are perfect, it’s about 2” too large in the waist but puffy jackets are going to be a bit bulky by design obviously.
With a base layer and athletic fit light fleece, I can wear the Kenai over it and not be constricted, and my Ultra NX rain jacket in a Medium fits over everything, but not with any room to spare.
I had planned on getting the Super Down instead, as I’m thinking it will be used primarily for glassing and at camp, but I’m glad I picked up the Kenai as it’s much quieter for hunting and probably a better choice if we end up doing more “run and gun” type hunting.
If it’s in 30-40 degrees and breezy, covering some ground with packs on but stopping to call and glass for 15-20 minutes at a time, I didn’t want to constantly be taking a down jacket on and off.
The only downside I’ve found to the Kenai so far is that it’s bulky. It will eat up the majority of the room in a day pack if you let it. Hopefully it will be worn a lot which will negate this, but I found that it fits perfectly in a 6x10 sleeping bag stuff sack. It can be compressed much smaller than that for a pack in, but it takes some effort.
