Boy Rib Bomber Jacket Little Kids Big Kids Acronym, it would be technical. And this black liner jacket represents why. Its outer shell is formed using WINDSTOPPER® — which, as the name implies, makes it fully windproof — and then it’s padded with PrimaLoft® for Denim, too. There’s a load of pockets at the front, as well — as is typical of the Berlin-based label — and a sling at the back so you can carry it over your shoulder.
