Our onesies are crafted from 100% polyester, offering a soft, cotton-like feel and designed specifically for sublimation printing. Featuring a lap shoulder design, they allow for easy removal, especially during messy changes. Please note, these onesies resist fading, peeling, and shrinking. Sublimation printing uses a dye process on polyester fabric, which may result in unique imperfections or creases, commonly found in areas such as the armpits, sleeves, shoulders, and sides.
