More Than Just a Swaddle

This isn’t your average baby burrito. Our swaddle sleep sacks are thoughtfully engineered to mimic a calming hug—so baby feels secure, and you feel like a sleep magician.

Crafted from buttery-soft bamboo rayon and filled with a hypoallergenic down-alternative, they’re OEKO-TEXⓇ Standard 100 certified for safety and softness. With a four-way zipper and optional belly band, every detail is designed to help baby sleep longer and deeper—no wrestling with Velcro required.

Why Choose the gunamuna Swaddle Sleep Sacks?

Like a Hug, But Smarter
Evenly distributed weight helps soothe baby into dreamier sleep, while the wide fit at the bottom supports the natural “froggy” leg position for healthy hip development.

Total Flexibility for Arms In or Out
Swaddle snug or go arms-free—perfect for babies ready to roll and parents ready to stop re-swaddling mid-nap.

WONDERZiPⓇ for Stress-Free Changes
Our patented genius 4-way zipper means diaper changes happen without waking baby—or fully unwrapping them. Gamechanger.

Safety You Can Count On
Our swaddles meet the highest standards for safety and comfort. Every sack is rigorously tested in JPMA-certified labs and approved by Certified Pediatric Sleep Consultants.
