Infrared energy has been proven to improve the body's circulation. Increased circulation improves oxygen levels in the body, enabling you to use less energy, improve overall warmth and increase your time in the water. This process has been proven in strict scientific studies to outperform similar technologies. Designed to provide more warmth with less bulk, the Base Layer pattern is a form fitting design.
