Fit is an issue for me. I'm 6'1" with broad shoulders and back and about 36" waist...not obese, but not super-trim...normally fit for an active city dweller.
The Large size fit well around the waist, and the arm length was just right. But the shoulders-chest area was just a touch too tight to make it a reasonable fit, especially if I needed to wear something other than a base layer.
The XL size was a bit on the larger side overall. Shoulders were good, but there's a bit too much material around the waist and a touch long in sleeves.
I'm a hard person to fit in general (broad shoulders, narrower waist), so this is no surprise...just a note to others like me.
Anyway, other than fit issues, this seems like it will be an awesome jacket. I just picked one up but haven't had the opportunity to use it in the field. It seems to be within the family of the Patagonia-like down sweater field of lightweight down or synthetic insulation layers. I like the fact that it has a hood, which to me makes it more versatile.
Good details...inside water bottle pocket, high-ish hand pockets, lightweight. Might not be as compression packable as others given the fact that it has a hood.
I like the pull tabs on the inside hand pockets to snug the bottom elastic...there are also conventional drawstrings in the usual places around the hem and also in the hood.
Overall, five star jacket, minus one star for fit.
