Cleaning the sea and beaches from the tons of plastic that seriously endanger delicate ecosystems should be a priority for everyone. French brand Collégien does its part thanks to a new line of iconic slippers. It's FOR A CLEAN OCEAN: these non-slip socks have been made with Seaqual® Yarn, a yarn made entirely from plastics and debris recovered from our oceans and the reuse of PET bottles. The commitment to be increasingly eco-sustainable is combined with a distinctive style, made of comfort, new palettes, and surprising designs, as has been the case since 1947, the year the brand was founded.
