Kirkland Signature Size 5 diapers are designed for babies weighing 27 pounds or more, offering dependable protection and comfort in a bulk 168-count pack. The thin-by-design construction features faster absorption technology, validated by third-party lab testing against the previous Kirkland Signature design after multiple insults.

Each diaper includes a super absorbent core that helps keep baby dry and comfortable, along with a pocketed waistband engineered to contain blowouts. A wetness indicator turns blue when wet for easy checking, and a next size indicator helps parents know when it's time to move up. The diapers are hypoallergenic and dermatologically tested to be gentle on sensitive skin.
