UYN Thermoshirt Fusyon Biotech

Face winter with a new ally. The FUSYON BIOTECH underwear shirt harnesses the power of nature to provide you with an excellent sense of natural warmth while keeping your body cool and dry. The thermoregulating properties of fine merino wool combine with the breathable qualities of Ecolypt fiber derived from the eucalyptus plant. The Natex biofiber ensures maximum drying speed, while the elastic Flexicorn fiber made from corn seeds contributes to an ergonomic, body-hugging fit without compression.
