Designed specifically to meet the needs of the active outdoor person, the Thermal-Dry Long Johns are constructed using a revolutionary Merino blend. The hydrophobic fibres provide great moisture management and dries 20% faster than 100% merino yarns. The Merino blend regulates body heat, trapping it around the body to keep you warm. The blend also offers superior breathability, high insulation, durability and odour control to keep you feeling fresh for those multi-day hunts.
