I have the non hooded version. Wear it under a soft shell Teton jacket. Works well in the wind with the outer cover. Have not tried it under the SDPro puffy. Itll have to be real cold before I try that!
Pit zips are a big benefit for this unit IMO.
I liked the Kenai so well I just bought two Kenai Ultra's. These are my "Go To" jackets for about all my needs. The two I just bought, I got one in solid and use it as my everyday jacket all fall and winter long.
