I've had this for 2 years. OUTSTANDING! I can wear a T shirt and this, and good to the mid-low 40's. Take it along for the A/C when dining. Best windbreaker I've ever owned. Worth every penny. On a cold windy day, this is priceless.

This too is outstanding. Will insulate even when completely wet. Together both of these will compact to the size of a ball that will fit between your hands.
