Big ups to continual improvement and real world innovations like blackZERO aka #Geoprene on the 3MM Scipio as well as on the inside of the 2MM 2103 Jacket. Geoprene with blackZERO Technology is over 98% water impermeable and literally reflects your own body heat - making said products the lightest and warmest - pound for pound - in their class aka no smoke, real is real. #lovematuse #artplusfunction #da2006
