Wonderful!
Special Size Type: Quarter Zip, Size: Small, Color: Taupe
Wonderful soft fabric. Not too thick, not too thin - just right! Love the taupe color. I usually wear a small, but needed to size up to medium for the shoulders to have a bit more room to move when I run.

Pretty in Pink!
Special Size Type: Full Zip, Size: Large, Color: Flamingo Pink
I wear this jacket almost every day! The color is a pretty bubblegum pink and is just as shown in the ad. Being high quality, it does not fade nor bleed when you wash it, it is true to size but does have stretch for comfort. You can put this in the dryer and it does not shrink! The pockets are a decent size and have zippers to keep your items safe. It is thick enough to keep you warm but not too thick to where you will overheat. Perfect for a breezy day!
