Picky Kid Approved!!!
My son will only wear Primary underwear! He is very picky and he loves how comfy these are. We have them in so many colors and prints and will continue to buy more and more!

super soft!
Very soft and dont become scratchy like other brands after multiple washes and wears, we came back for next size up ( after outgrowing the smaller size which was in good enough condition to pass down even after potty training!) highly recommend!
