I bought this as a Christmas gift for my daughter, who is a runner.  She runs early in the morning when it's cold, is a very petite person who often can't find appropriately fitting clothing, and she wears her hair in a ponytail when running -- all of those things played into the purchase of this item.  And she absolutely LOVED it!  It was a perfect fit for her, snug, comfortable, cute, stylish, and best of all -- WARM!  It actually has fun little extras like a hoodie with a hole in it for her ponytail!  I was thrilled with the purchase, it was exactly what I hoped for.  Brooks is a quality company.
