Size large (5’ 9-3/4”; 151 lbs, 34G). I put this Payton turtleneck to the test as I shoveled snow this morning. It was the perfect layer under my lightweight down jacket. The knit is quite soft and comfortable. There are no scratchy areas or abrasive seams. The sleeves and torso are actually long enough for a tallish woman. It is formfitting, but makes a great layering piece for that reason. I can’t wait to use this as the centerpiece of my wardrobe for a spring trip to cold climates. I think it will be perfect for a chilly overnight airplane flight.
