Designed to insulate against the cold, yet remain breathable when it’s hot, the HANRO Woolen Silk Long leg is tailored from a blend of luxurious merino wool and silk. Part of the HANRO Woolen Silk Collection, these men’s long johns feature a functional fly, a seamed pouch and a saddle gusset for astonishing comfort and a smooth appearance beneath clothing. Seamless sides with a soft elastic waistband and elasticized cuffs at the bottom of the pant leg ensure a custom fit.
