Nature and Science have joined forces to produce a silk garment which can now help thermo regulate the bodys temperature and dramatically speed up the dispersion and rapid evaporation of the boys perspiration Thermasilk EC2 Qwik Dri silk line of underwear takes the best nature has to offer to a new level of performance and comfort FEATURES Terramars Thermasilk EC2 Qwik Dri has the ability to actually lift moisture molecules away from the body and eak them down for rapid evaporation This patented process does not involve the use of add on chemicals but is actually a permanent molecule change in the silk fibers Since the EC2 Qwik Dri process alters the molecular signature of the yarns in our fabric the moisture control is permanent It wont wash out or wear off
