ZIGJOY Shark-Fin Transitional Swaddle Sack – 0.5 Tog Bamboo Rayon, 3-12 Months, 2-Way Zipper, Purple

Overview

Introducing the ZIGJOY Shark-Fin Transitional Swaddle Sack. Built for growing babies, it blends a feather-soft hand with practical design. Crafted from 95% rayon made from bamboo and 5% spandex, this 0.5 tog layer offers breathable, gentle warmth for rooms around 23–27°C (73–81°F). The purple hue adds a touch of whimsy to bedtime routines while staying easy to wash and wear.

Two growth-minded sizes

The sleep sack is offered in M and L, each tuned to different stages of development. M fits roughly 3–6 months (up to 27 in / 18 lb), while L covers 6–12 months (up to 31 in / 30 lb). This sizing helps you choose a secure, comfortable wrap as your baby grows, reducing the need to switch products too soon.

• Size M: 3–6 months, up to 27 inches/18 pounds
• Size L: 6–12 months, up to 31 inches/30 pounds
• 0.5 tog for versatile room temperatures
• 98% soft-touch blend for gentle contact with baby skin

Breathable, baby-friendly fabric

The fabric blend emphasizes softness and stretch, helping the garment move with your child and wick warmth without overheating. It stays resilient after frequent washing, keeping its shape and feel wash after wash.

• Breathable bamboo rayon with a touch of spandex for flexibility
• Durable, machine-washable construction

Safe, transitional design

The Shark-Fin transition sleep sack replaces loose swaddling with a secure wearable blanket. Sleeves reduce the chances of loose fabrics covering the face while still allowing self-soothing through finger access. It’s ideal for newborns and infants starting to roll.

• Sleeved design supports safe self-soothing
• Prevents loose blankets from drifting over the baby

Practical, parent-friendly features

Everyday use becomes easier thanks to a smoothly functioning 2-Way zipper. The upgraded SBS zipper glides with less wear, making diaper changes quicker and less disruptive. A widened hem gives room for hip joints and free leg movement as your little one grows.

• 2-Way SBS zipper for quick, gentle diaper changes
• Widened hem supports hip growth and unrestricted leg kicking
• Easy care: machine washable and quick to dry

Note: Fit is influenced by baby size and growth. For longer usability, allow extra space according to the size chart. The purple palette adds a friendly, modern look to bedtime routines.
