The award-winning 4 Season Ultimate Toddler Sleep Bag keeps your toddler at a perfect temperature throughout the night, year-round. That means there’s no need to worry about which weight sleeping sack to use, or whether your child will be too hot or cold while sleeping – they’ll always be just right!

Made with super-fine and supremely breathable merino wool, it helps keep your toddler warm when it’s cold and cool when it’s warm. That temperature regulation means that your child will sleep comfortably throughout the night– and that means a better night’s sleep for you too.

It comes in a universal size that fits kids from 2 to 4 years. It saves you buying a different sleeping bag for different seasons, as well as buying larger ones as they grow. You just need one Woolino sleep bag for your toddler that will fit for 2 years

• 100% Natural 
  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.
• Excellent value 
  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.
• Travel friendly 
  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.
