Like a sweet breeze for long runs and hot days, Capilene 2 features an open knit that invites airflow to keep you cool and provides excellent wicking and exceptional breathability to keep you dry. Also insulative enough for chilly days when winter hasn't quite released its grip, it's the fastest-drying of our performance baselayer fabrics. With a feminine neck and elbow-length sleeves that stay put. Raglan-style sleeves and flat-ribbed underarm panels merge out ofthe way of straps to eliminate chafe. Made from 4-oz 100% polyester (54% recycled) with Gladiodor natural odor control for the garment. Recyclable through the Common Threads Recycling Program.
