Oytex™ rubber is FSC™ certified and contains biobased carbon from recycled oyster shells, sugar cane, plant oil and renewable rubber. The polyester fabric laminate on both sides is 100% rPET. Oytex™ is an eco-friendly replacement for neoprene. With the same dual-sided imprint capabilities as our Duplex line, with all the stretch and insulating properties, it's a more sustainable alternative to traditional neoprene. Pretty cool, right? This item takes the classic, beloved shape of the Kolder Kaddy and extends the size to fit tall cans; hard seltzers, light beer, and more! Now there's a can holder for every occasion.
