WHY BIRD & BEAN? Made from the highest quality, extra soft bamboo viscose fabric, our baby pajamas + kid's pajamas are a hit! Our bamboo pajamas are made with our buttery soft bamboo/spandex blend with the perfect amount of stretch + softness. Plus, we make our fabric slightly heavier weight to make our pieces last. Our fabric will hold its shape, color, + quality wash after wash. Please read our many reviews from happy customers!
