They’re comfortable, they’re practical, and they’ve stood the test of time. We’re talking about FlapJacks, our modern take on the classic long john! Wildly popular in their day (oh, 150 years or so ago) it’s easy to see why this unisex style is making a big comeback! Stretchy, comfy and warm, our FlapJacks have a button-down front, a contrasting flat-lock stitch around the seams, and most importantly, the ever-so-handy trap door at the “bear bottom” for that midnight run to the water closet (Adult Sizes Only)! Made from 100% cotton/1 x 1 ribbed knit, FlapJacks are hailed by young and old timers alike and come in a range of sizes perfect for the whole “fam damily”. Sizes: XS, S, M, L, XL 

All new stock infant, kids, and youth Flap Jacks do not open.
