Our Woolino Ultimate 4 Season Toddler Sleep Bags are designed to be used throughout the year, for two years.
How do we do that?
The merino wool we use is supremely breathable, keeping your toddler warm when it’s cold and cool when it’s hot. That temperature regulation means that your child will sleep comfortably throughout the night, year-round – and that means a better night’s sleep for you too.
Our universal sizing means that it will fit a toddler from 2 to 4 years. This consistency in sleepwear will allow them to always associate the comfort of their sleep bag with a good night’s sleep.
Pure silky-soft hypoallergenic merino wool lining and the finest organic cotton outer.
4 Season use
Unlike most of the 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 any room temp. 63-77F (17-25C). Because of Merino’s unique ability to regulate body temperature, it keeps your baby warm when it's cold and cool when it's hot.
Grows with your child
It has a universal size so it can be used for kids 2 to 4 years old. For smaller kids, simply close the underarm snaps to adjust the fit.
It will save you buying a different sleep sack every few months. It is the only baby sleep bag your toddler will need, in winter or summer, for 2 years.
Designed to be practical
It features double shoulder snaps and a one-way side zipper, so it opens up completely flat for easy dressing without waking the baby! For easy nighttime diaper changes, you can open the bottom only. It also has zipper-pull guards to protect baby's skin and to discourage them from chewing on the zipper pull.
A closable seat-belt opening allows for easy transfer between stroller, car seat and bed, so you can keep your child’s sleep routine intact while on the go.
In addition to Merino being naturally anti-bacterial and odor repellent, Woolino sleeping bags are machine washable and can be tumble dried on 'no heat' setting. See care instructions here.
Naturally fire resistant
Wool is naturally flame resistant and the safest fiber to have next to your toddler’s body. Woolino sleep bags meet all US CPSC children safety requirements.
Woolino 4 Season Sleep Bags are made with Woolmark and Oeko-Tex 100 certified merino wool and GOTS and Oeko-Tex 100 certified organic cotton. We use nickel, lead and phthalates free YKK snaps and zippers, which are also Oeko-Tex 100 certified.
