GUNAMUNA Sleep Sacks for Babies & Toddlers (3-9 Months) | 1.0 TOG, WonderZiP Zipper

Comfortable transitional sleep for growing babies

Meet the GUNAMUNA Sleep Sack designed for babies 3–9 months. This sleeveless transitional option helps bridge the gap between swaddle and a wearable sleep solution, offering a secure yet spacious fit that respects your little one’s changing sleep needs. The soft, breathable feel invites calm, while the simple silhouette supports natural movement during those 40 winks and longer naps alike.

Transitional design for growing babies

Specifically crafted to ease the shift from swaddling to a full sleep bag, this sleeveless design keeps the torso snug and the limbs free to stretch and kick. That balance can help your baby feel contained without feeling restricted, which may support smoother bedtimes as they learn new sleep patterns.

• Secure, cozy fit that adapts as your baby grows
• Room for arms and legs to move comfortably

Ultra-soft fabric and flexible fit

The garment uses premium, ultra-soft materials in a wider, longer shape, giving babies room to move while maintaining a soothing, snug feel. The plush texture helps little ones settle into sleep with less fuss, and the sleeveless cut reduces bulk at the shoulders while preserving warmth where it’s needed.

• Soft, breathable fabric for cuddle-worthy comfort
• Wider, longer silhouette that respects growing bodies

Smart TOG options for every season

The Sleep Sack offers 0.5, 1.0, and 2.5 TOG choices to match the room environment. The 1.0 and 2.5 TOG versions include hypoallergenic microfiber fill for plush warmth, while the 0.5 TOG is ideal for warmer rooms, helping you tailor warmth without adding weight.

• 0.5 TOG: ideal for warmer rooms
• 1.0 TOG: plush warmth with microfiber fill
• 2.5 TOG: extra warmth for cooler nights

Easy diaper changes with WONDERZiP

Our full-length WonderZiP zipper is designed for quick, quiet diaper changes while the baby remains comfortably snug. This feature is especially handy during bedtime routines when time and calm are at a premium.

• Full-length zipper for fast, fuss-free changes
• Nighttime routine stays calm and uninterrupted

Sleep-friendly style & safety first

The Sleep Sack comes in calming, muted colors that can help create a soothing sleep environment. It’s designed in accordance with infant safety guidelines and intentionally contains no weighted materials, prioritizing a secure, breathable fit as your child naps and grows.

Real-life use and versatility

Parents often notice smoother bedtimes and fewer wake-ups during transitions, thanks to the sack’s snug yet forgiving design. The sleeveless cut helps you layer easily while giving babies the freedom to move naturally, which can support repeated, restful naps throughout the day and night.
