Mons Royale Olympos Men’s Long John

Mons Royale men’s underpants for the coldest days of the year, for anyone looking for warmth and comfort. The long johns are made of a merino wool blend with a hint of nylon and elastane. Wool warms perfectly while drying out quickly and naturally repels odors. Synthetic fibers, in turn, extend the life of the pant and give it flexibility when moving.
