Incredibly warm and functional jacket! - Rab Neutrino Pro Jacket - Men's

After much research and having previously owned a lighter-weight Rab jacket, I sprung for this pricey Neutrino Pro jacket for outdoor winter activities in the Utah mountains and desert. After a month of frequent use, I can honestly say it is the warmest and most comfortable cold weather jacket I have ever owned. Has a greater volume of 800 fill power down than any other jacket I've owned or tried, and in concert with the wind and water resistant outer, provides unsurpassed protection from the cold. Sheds light rain and snow very well. The pre-bent sleeves make for unrestricted arm movement. The hood is extremely roomy and requires using the limit of its adjustments to fit around an un-helmeted head, but is toasty warm and the brim stiffener is a nice touch. Sleeves and hem adjustments are excellent. Pockets are very warm.
I am 5'7" tall and 155 pound with an athletic build, and the size Medium fits a bit loosely and allows for layering of a heavy sweater or fleece jacket beneath.
The only issue I've had is pulling away a bit of the baffle stitching in the sleeve while donning the jacket with keys in my hand. I would have expected more durable stitching to go with the otherwise excellent materials and workmanship.
