Kirkland Signature Size 6 Diapers are designed for babies weighing 35 pounds and up. This 132-count box provides exceptional value with Costco's trusted private-label quality that meets or exceeds leading national brands.

These diapers feature a soft, breathable outer cover with an ultra-absorbent core that locks away wetness for up to 12 hours. The active fit technology includes stretchy side panels for a secure fit and gentle leg cuffs that move with your baby. A pocketed waistband helps prevent blowouts. Made with at least 23% plant-based materials by weight, they are dermatologically tested and hypoallergenic.

Convenient features include a wetness indicator that changes color when wet and a next-size-up indicator to help parents know when it's time to move to a larger size.
