We live for shopping intel (yes, even moms want to know what's trending). Pinterest tipped us off that not only are saves for college backpacks up 54 percent since January 2018 (no surprise there — back-to-school shopping is definitely on our minds [1]), but that the most popular backpack is none other than the Herschel Supply Co. Daypack Backpack [2] ($40). It's the quintessential one-pocket bag that'll get your young one through the school year. It comes in eight colors (you can see them all on Herschel's website [3]). Snag it before your kid even has to ask you for it — or get one for yourself and watch as they beg you to borrow it.
