Silky-soft hypoallergenic merino wool lining and the finest organic cotton outer.
4 Season use
Unlike other brand sleep sacks that come in either winter or summer weight/TOG rating, the Woolino 4 Season Sleep Bag can be used year-round. It’s suitable for room temperature 63-75F (17-24C). Because of merino’s unique ability to regulate body temperature, it helps keep your baby warm when it's cold and cool when it's hot.
Grows with your baby
It is designed to fit kids 2 to 4 years old. For smaller children, adjust the fit by closing the underarm snaps.
It saves you buying a different sleep bag every few months. It’s the only sleep bag your toddler will need, in winter or summer, for 2 years.
Designed to be practical
It features double shoulder snaps and a two-way side zipper, so you can open it completely flat for easy dressing without waking the baby! For easy nighttime diaper changes, you can open the bottom only. Zipper-pull guards protect baby's skin and discourage child from chewing on the zipper pull.
A closable seatbelt opening allows for easy transfer between stroller, car seat, and crib, so you can keep your baby’s sleep routine intact while on the go.
Replaces loose blankets
Helps your child to stay covered through the night.
Glow-In-The-Dark fabric needs to "charge"
Glow-In-The-Dark material needs to be exposed to bright light for at least half an hour before use to glow properly. Glow lasts for approximately three to four hours. It requires fully dark room for the glow to be visible. The glow effect will become weaker over time because of rubbing and washing.
