The material of the jacket is quite flimsy and provides zero warmth (not the level you would expect from a windbreaker). The sleeves are the biggest drawback. The jacket has an attached sleeve extension with thumb-holes, which was a selling point for me. The material is not elasticized at all so the sleeve is wide and floppy - the thumb-holes are awkwardly placed (they fall to the underside of the wrist) and too small so if you try to use them it looks like a child wearing an adult's sleeve. Very disappointed.
