The Kenai Series of breathable synthetic insulating layers are for cold-weather hunts and keeping your temperature regulated during high- and low-level activity. Featuring an all-new siliconized water-resistant 3DeFX+ insulation, upgraded quilt-free design, and a streamlined fit, the new Kenai Series is better than ever.
I wore this on a week hunt in Gallatin National Forest, MT. I camped at 8K and hunted up to 9K. Temps were 20 to 60 degrees with sun, snow, and rain. The jacket shed water really well and the pit vents were great during ascents. When it got warm, it stuffed really small into my pack.
