QNOOP is a brand that ticks all the sustainability boxes, aside from the fact that they have a very simple but ingenious design feature that allows the whole collection of Qnoop socks to come together! With a button on one sock. And a loop on the other. Easy as that! No more missing socks. No more throwing out lonely socks. Pretty smart, pretty sustainable. This brand also plants trees to compensate for the CO2 emission!
