Exercising girls (and some boys) with long hair wear pony tails. Now instead of an awkward bulge under their winter hats, ponytails are free to drift in the wind through an ingenious integrated loop. Heads and ears are snugly protected beneath a colorful, warm layer of water-resistant Polartec® fleece. www.trailheads.com Assorted colors. Retails for $26 —Amber Pratt
