We purchase every product we review with our own funds — we never accept anything from product manufacturers.

Onesies for kids are very different than onesies for babies. Kids’ onesies are usually more of a costume or pajama than a base layer or tee. We particularly like onesies that are cozy for sleep as well as for dress up. Look for solid stitching, smooth zippers, and ample openings from neck to inseam. Unicorns are having a moment right now, so many of our top choices reflect this trend. Look for plush, breathable fabric that is as comfy on the inside as it is on the outside.

Other Products We Considered
The BestReviews editorial team researches hundreds of products based on consumer reviews, brand quality, and value. We then choose a shorter list for in-depth research and testing before finalizing our top picks. These are the products we considered that ultimately didn't make our top 5.
