LAPASA Boys Midweight Heat Generating Crew Neck Thermal Underwear B18R2

HEAT GENERATING: LAPASA heat-generating thermals are made of an acrylic, polyester, nylon, and spandex blend that wicks moisture from your body and converts kinetic energy into heat.

LAYERABLE WARMTH: These thermals are easy to wear under other clothes and are an excellent way to stay warm without the bulk.

STRETCH: These thermal underwear are designed to flex with any movement and promote full range of motion.

SNUG: The cosy fit ensures no bunching around the waistline and sleeves to reduce heat loss.

STAYS FRESH: A special material treatment helps these thermals remain fresh even after use.
