Early forms of #geoprene were on every Apollo Space Mission and we are dedicated to continual improvement. See the link in our IG bio to pre-book the Ichiban aka the new new 3MM Hooded Scipio with blackZERO #geoprene and Hidden Chamber Technology. Says Matuse Family Member, @mister_tickle_hands, regarding the warmest and lightest Hooded Fullsuit - pound for pound - on the market: "As far as the suit goes it is hands down the warmest 3mm I have ever worn. The water is between 43-45 degrees still and I have been putting in marathon sessions up to 5 hours at a time without getting the slightest bit cold. Pretty much this suit in my opinion is the future of wetsuits. Light flexible and warm as _ _ _ _ ! What else could you ask for?!" The Scipio's blackZERO Technology literally reflects natural body heat back inward, providing more insulation with less bulk, weight, hollow-fibers, batteries, etc. And Hidden Chamber Technology is a 3 substrate material (i.e., on your core) where the perforated layer in the middle functions as mini pressure cookers when in contact with your body's natural radiant heat. 10 years and running, our supply chain is permanently switched on and we are here to serve and create your most innovative product needs and specifications.
