Luke Thomas, Dylan Riley, Matt Connors and Zane Reynolds (above) are the trendy artists, hailing from hip places like New York and Los Angeles, who have been commissioned for the new range.
The bags are printed canvas and feature leather trim and a Saint Laurent embossed exterior zip.
Sure they are technically sitting in the men's ranges, but we're going to go out on a limb and say backpacks are unisex.
The bags are £530 and are available in store and online at ysl.com
Seems the backpack trend is here to stay then.
