Ichiban savings via pre-orders on the Ichiban made possible via the link in our IG bio. As noted, derived from calcium carbonate (i.e., limestone rock, that's not pictured) rather than the petroleum additives used to produce traditional neoprene, #geoprene is 98% water impermeable compared to the standard 65% offered by standard materials. Hence, because of the water it does not absorb, #geoprene is warmer, lighter, dries faster, lasts longer and is kinder to Mother Nature (i.e., as the quick consumption of lesser-than products is arguably one of the most formative environmental culprits) PC @michael.kew #lovematuse #ckth #da2006
