I'm thinking of getting a set of Kuiu Kenai pants to layer under/over my regular hunting pants. They'll be for my Eastern whitetail hunting endeavors as my regular puffy pants for Western stuff are just too loud for close quarters whitetail hunts. I'll be hunting central/northern Pennsylvania, hiking in 1-2 miles and then possibly doing an all day sit. Temps likely to be mid 20s to mid 40s when I use the Kenai, maybe a bit colder on the low end. Would something like a kuiu attack be warm enough with the kenai or would you be looking at something with a decent fleece lining like the guides?
