PREMIUM FABRICS FOR BEST COMFORT - The award-winning 4 Season® Ultimate Baby Sleep Bag keeps your baby 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 baby will be too hot or cold while sleeping – they’ll always be just right!

SAFER, BETTER, AND LONGER SLEEP - Made with super-fine and supremely breathable merino wool, it helps keep your baby warm when it’s cold and cool when it’s warm. That temperature regulation means that your baby will sleep comfortably throughout the night– and that means a better night's sleep for you too. Cuddly-soft organic cotton outer adds to the comfort as it's perfect for the most delicate skin.

THE ONLY SLEEP BAG YOU NEED - It comes in a universal size that fits babies from 2 months to 2 years. So, instead of 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 baby, right up until they turn two!

 

  • Premium Natural Fabrics
    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 has a universal size so it can be used for babies 2 months up to 2 years old. For smaller babies, simply close the underarm snaps to adjust the fit.
  • Excellent value 
    You don’t have to buy a different sleep bag every few months. Woolino Ultimate 4-Season Sleep Bag is the only baby sleep bag your baby needs, in winter or summer, until they turn two years old.
  • Designed to be practical 
    It features double shoulder snaps and a two-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. Zipper-pull guards protect baby's skin and discourage baby 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.
  • A safer alternative to loose blankets
    Helps your baby stay covered through the night, replaces loose blankets in the crib, and promotes back sleeping.
  • Free Nursery Thermometer with a dressing guide included.

 

Machine wash on low (100°F max), use wool or mild detergent. Close zipper. Can be tumble dried on No Heat or Air Dry setting. Hang to dry whenever possible. To refresh and reduce washing, turn garment inside-out and air often.

We do not recommend sizing up. The sleep bag should be well-fitted around your child's upper body for a safe and secure fit. We suggest using our recommended sizing guidelines to find the correct size based on your child's age, height, and weight. Your baby should not be below the minimum recommended weight.

Excellent, But Not Strong Enough
Color: Monsieur Acorn - Large
This has become the most engaged my dog has ever been with a toy. He chewed these acorns for an hour and a half STRAIGHT. Sadly, he was able to shred both acorns by this time. For dogs with a normal chewing and shredding amount, this toy would be perfect. However, for a super chewer like our dog (Lab/Malamute), it seems like we're going to need something stronger...

A favorite for my small destroyers
Color: Monsieur Acorn - Large, Color: Monsieur Acorn - Large
My small destroyer dogs LOVE these toys and are always surprised to find another toy after the first and second violent de-stuffing. Definitely a supervision toy for safety, but my terriers love doing their thing when these come out and they last much longer than I had anticipated. Color, design and value all as described, however I literally do not remember if it did squeak because the squeaker would be the first thing gone

Received this today, and it lasted less than an hour before it had to be taken away to prevent it being eaten.

It looks like a Totoro
Color: Hare - Large
Great toy ! Pibble loves it! an it looks just like a Totoro which is huge plus at our house. These are very durable and once de gloved the body will last a very long time if your dog isn’t a big chewer.

Very fun toy at a great price
Color: Monsieur Acorn - Large
My dog (an American Staffordshire Terrier) lovessss to chew and destroy things! We have literally gotten three of these because she loves them so much, and they last, too!! You get the first toy, which my dog rips open. I’m not sure exactly how long it takes for her to destroy it, maybe a few days to a week. Then another little toy (with a sad face lol) is revealed. She highly enjoys this one, as well! Finally, she rips the fabric off that and then a blue, spiky ball is revealed. She lovesss to chew on it and I think the bumps are a nice texture for her mouth. She is quite a strong chewer and the ball lasts a long time!! No toy lasts forever and I have found under dog toys are quite expensive and that’s no guarantee of how long it will actually last. But I am perfectly fine with spending ~$11 every once in a while for these toys because I know she loves them, and they are not immediately destroyed.
