Every My Brest Friend pillow comes "ready to go," covered in a fashion-forward print of your choosing. But the options don't end there. Many moms enjoy buying extra slipcovers so that when spit-up or leaky diapers strike, they can toss the slipcover into the washer without missing a beat. Slipcovers are 100% cotton. Machine washable in the gentle cycle in warm water. All covers fit all styles of My Brest Friend pillows, including the travel pillow.
