Kirkland Signature Ultra Soft Diapers in Size 1 are designed for babies weighing 8 to 14 lbs, offering a bulk count of 160 diapers per box. The super-absorbent core quickly absorbs moisture and provides up to 12 hours of dryness protection, making these diapers suitable for both day and nighttime use.

The diaper features a hypoallergenic liner that is gentle on sensitive skin, dermatest certified as of November 2025. Cross-over tabs provide a secure, cozy fit, while the pocketed waistband helps contain blowouts. A color-changing wetness indicator turns blue when wet for easy monitoring, and a next-size indicator helps parents know when to size up. The breathable outer cover keeps babies comfortable throughout the day.

These diapers are made without fragrance, parabens, phthalates, lotions, elemental chlorine, or natural rubber latex, and are not tested on animals. Inner bags are made with 20% post-consumer recycled materials, and the product carries Sustainable Forestry Initiative (SFI-01644) certified sourcing.
