Whether it's a sunny day hike or a winter workout, it'll keep you comfortable. When it comes to care, you can machine wash it in cold water. Use a mild detergent to preserve the fabric and the special technologies. Avoid using bleach as it might damage the odor - control and sun - protection features. After washing, tumble dry on low.
