Light, stretchy, very breathable fabric, not cut as trim as my softshell jacket by this company, so there is plenty of room to move and wear a light undershirt. I have used it to kayak, fish and run outside in moderate 50 degree breezy weather. It can be cold as it does not have a brushed lining other than the collar, nor is it windblocking, if you are not moving or layer it. Held up well in laundering, and tough fabric won't 'pick' when rubbed by heavy gear.
The fit is good for a small female by itself or with a light undershirt. I like the arm sleeve pocket for my keys.
Also, it is not too 'techy' or logo emblazoned to wear in the grocery store on the way in from the beach. My pet peeve, I don't like being used as a sign board for a clothing company, even a very good one. Due to not having a brushed interior lining and being noisey, I'll give a 4/5. The plus to not having a brushed interior means that the fabric is non-bunching over a lighter underlayer.
