Why We Made This

Nothing saps your concentration as fast as frigid temps and wet, freezing conditions, but continuing to stack layers will restrict your ability to travel through the mountains. By upgrading our Blizzard Parka to an innovative synthetic insulation that uses trapped air to replicate the warmth and compressibility of down, we’re able to add warm-when-wet performance—plus significantly reduce bulk—so you’ll be comfortable and mobile in a whiteout.

Those of you on the fence about this jacket should go for it. Just got back from a duck hunt in a blizzard and temperatures raning in the teens. I had a merino base layer and a hoody on and I was warm and dry.

I have worn this in the interior of Alaska hunting coyotes at 25 below zero and was perfectly warm and comfortable. This jacket is by far the best jacket ever designed for extreme weather. Thank you SITKA!

I purchased the Blizzard Aerolite Parka, Blizzard Aerolite Bib Pants and Blizzard GTX Mitts from Sitka to use duck hunting on Prince William Sound in Alaska and Pamlico Sound in North Carolina. The season in Alaska was brutal this year with constant driving rain and temps in the 30’s making for some long days. The blizzard gear kept me warm and dry and blended in perfectly with the Alaskan landscape. I would highly recommend this system if you are going to hunt in severe weather where staying warm and dry is paramount.

This jacket is extremely well built and will dominate the Western weather where I live. The jacket is extremely comfortable and has pocket storage for days. Excited to put it through its paces this fall during our late season elk hunts and frigid winter months during the lion hunts as well. Sitka built this one right.
