Dirtbike Rider Pj SetThe softest, stretchiest summer PJ set around, designed for all night comfort. Made from a buttery soft bamboo blend with just the right amount of stretch. The drop crotch shorts give kids extra freedom to move. The waistband is designed differently to our long PJ pants and features a long line fit means the shorts drop below the knees for extra coverage and style. Fit tip: Theyre super stretchy, but we recommend sizing up for extra room to grow.
