ZIZZ Newborn Summer Sleep Sack

The ZIZZ Newborn Summer Sleep Sack is designed to provide calm, secure, and comfortable rest from your baby’s very first days.

Crafted from polished cotton with a soft matte finish, this refined sleep sack features elegant decorative pockets with pearlescent buttons and a graceful fold-over collar. The collar is fully finished with Chantilly lace and can be gently adjusted to frame or softly shield your baby’s face during rest.

The interior is lined with 100% breathable cotton, while a lightweight, hypoallergenic padding makes it ideal for spring and summer use. For added comfort, the back is softly structured with gentle padded sides and a subtle pillow area to support relaxed sleep.

Designed for hospital discharge and stroller walks, this summer sleep sack offers a safe and beautiful alternative to loose blankets.

Customer Reviews (4.6 / 5 · 5 reviews)

Alexander N. ★★★★★

My little one falls asleep so much faster since we started using this sack—the secure fit really does calm them down right away. It’s lightweight enough for summer nights, and the cotton feels breathable against their skin.

Elizabeth ★★★★★

The polished cotton feels so smooth and breathable against her skin, and the mat texture keeps her from overheating even on the warmest nights. She settles into it faster than any blanket we tried, and the secure fit means no kicked-off coverings at 3 a.m.

Joshua I. ★★★★★

The double zipper makes middle-of-the-night diaper changes so much easier than the single-zip sleep sacks I used before. My newborn seems to settle faster since we started using this, and the cotton fabric breathes well enough for these warm summer nights.
