Men's thermal long johns are crafted from silky soft viscose fibers for superior comfort, blended with polyester for enhanced durability and warmth. The yarns are knitted using interlocking stitches to form tiny air pockets that trap heat and keep the cold at bay. Ideal for any winter sport or outdoor activity, these long johns offer optimal warmth during the cold months. They feature a soft Lycra waistband and a heavily brushed interior for a skin-friendly experience. The long johns also have soft Lycra cuffs and a convenient front fly opening. The interior is heavily brushed to provide extra warmth and a soft feel against the skin. All seams are flatlocked to ensure comfort and minimize chafing. Designed to be flexible and durable, these long johns lack side seams for an improved wear experience. They include a reinforced gusset and are tag-free for maximum comfort. Made from 50% viscose and 50% polyester, these long johns are available in waist sizes S (30-32), M (33-35), L (36-38), XL (39-41), and 2XL (42-44).
