Value in a product is defined by the length of time that it remains functional. For a wetsuit, functionality means, insulating, comfortable, flexible and durable. This is why we use #geoprene. Marketing jargon and PR notwithstanding, early forms of #geoprene were on every Apollo Space Mission (Apollo 12 pictured). Functionally superior because of its limestone-based composition, which results in a perfectly uniform microcell structure, #geoprene is 98% water impermeable compared to the standard 65% from petroleum derived neoprene. Hence, a Matuse suit is warmer, lighter, dries faster and lasts longer. It is also Kinder to Mother Nature not only because it is made from a more sustainable natural resource (i.e., it's 99.7% pure calcium carbonate source has roughly 3,000 years worth of readily available deposits) but also because it results in a finished product that maintains its intended utility (and economic rationale to the end user) for many moons aka years aka ask a Matuse suit owner near you PC @nasa #ckth #unapologeticallyichiban #lovematuse
