This Simplex all-in-one diaper from Swaddlebees really is so simple to use. The waterproof outer layer and 100% cotton inner layer offer superior absorbency, but allow for the addition of extra liners for heavy wetters or for nighttime use. Due to its ingenious design, the inner soaker can be partially removed for washing, ensuring the entire diaper, both inside and out, is fully clean. The adorable fabrics make this all-in-one diaper especially attractive.
