Polarmax's double layer thermals feature a unique construction with two layers of fabric connected back to back. This design creates open spaces between the layers, which effectively trap and hold warm air. The result is exceptional insulation that keeps you cozy and comfortable in any weather. To enhance performance, these thermals are expertly manufactured using Acclimate Dry fibers. These innovative fibers actively transport moisture away from your skin, ensuring that you stay warm, dry, and incredibly comfortable throughout the day.
