The goal with the UA Woven collection was to make the perfect set of warmups that keep your muscles ready to work for any sport and also pack up supersmall in your bag so you can take them anywhere. UA Storm technology repels water without sacrificing breathability. Lightweight stretch-woven fabric is durable, quick-drying & moves with you. 4-way stretch material moves better in every direction. Soft knit waistband with internal drawcord. Open hand pockets & flap-closure cargo pockets. Uses a fluorine-free water repellent treatment.
