Have only had this a couple weeks now, haven't had the chance to really test it as I would like as the weather has been so nice here, but the initial impression from when I have used it so far its this is an awesome, light, warm, super versatile piece.
For fit reference I'm 5'10", 160lbs, 40 inch chest with broad shoulders and long arms and the Medium fits great. Nice trim athletic fit, would layer under a shell great.
Great hand feel to the material, much more pliable and quieter than a hardshell, with a little stretch to it, but still feels plenty tough.
Used it out waterskiing early a few mornings, was super impressed with the windproofing cruising around on the chilly lake when everyone else in the boat in a regular hoody was shivering I was totally comfortable.
This was also the only time I got to test the water repellency, everything that splashed on the jacket would bead right up with no real trace of moisture left on the jacket. This was a super limited test though.
After getting out of the water and being really cold I dried off, and tossed this back on over a t shirt and warmed right up. This provides lots of warmth for how light it is, definitely more insulating ability than I expected. Used it a couple nights camping and noticed the same thing.
Overall I really like this thing and think I have found my new go to jacket to toss in the back of the car or bottom of the pack 'just in case' Looking forward to being able to test it fully it once it cools down moving into fall.
