Collien denim eco bleach is our cool 80s jeans made from 100% Italian denim. The jeans are made of GOTS-certified organic cotton denim, which, like all wunderwerk jeans, are produced completely without toxic chemicals as well as chitosan (from crab shells) and with extremely low water consumption (9l compared to 140-160l for conventional processes). Since spring 2014, we have been delivering our jeans productions without plastic packaging ("polybag") laced with a band of organic cotton in such a way that the goods are not damaged or soiled during transport.
