"Just recieved today. I am an Arcteryx fan, but was very impressed by initial wear. Its a very light and comfy, so earl fall/spring would be a stand alone. Colder temps, seem an excellent layer, but not a stand alone in winter temps."

"1 of the best jackets ive ever gotten. Its the best lightweight but still warm and extremely mobile type jacket. Its like a combo of the ambient and aerolite jackets. Get it"
Great value for a 100% American made product.
"Very light weight and breathable. The insulation factor doesn't starting in until you're active and moving. One of the things of the many i like about the jacket is how easily it zip and the unique zipper pulls. This is a great fall stand alone jacket or spring time stand alone jacket. For those considering this jacket just keep in mind that gortex shell would recommend in wet weather."
Sitka MDWi Hoody
"Great active insulation for when on the go. Works great as a stand alone. Warm and dries fast. Full zip is great to vary ventilation and hood is a must when max warmth is needed. Full zip also allows for removing jacket without dumping the pack, can’t do that with a pullover. All in all a great piece to have."
This is a hoodie that is magical in nature
"This hoodie is magical in nature by how it uses this polertech alpha material that somehow insulates you like none other worn before..... Im being serious, im in cold weather below 40 and i feel great in this thing"
Great jacket
"The first thing you’ll notice is how light the jacket is- it weighs next to nothing. It’ll fool you though. Its very warm. Perfect for spring/fall weather. Great for the football game or a nice walk through the woods. The hood fits your head very well. Really nice jacket."
Awesome Jacket.
"Great for on the move on chilly days. Super breathable yet warm with the Alpha Insulation. If its windy, you'll feel it."
