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.

Dog loves it! For tough chewers for sure
Size: Medium/Large, Color: Dog Ness Monster - Large, Size: Medium/Large, Color: Dog Ness Monster - Large
Dog absolutely loves it, he’s super rough on all of his toys they usually last about 10 minutes bore they are torn to shreds. It’s lasting through his chewing so I’m happy. It’s also super cute.

Cute toy, dog really likes it. I had my doubts when I pulled it out, and honestly so did she, but the soft part bounces, so that got her going. We've had it for about a week. My dog is ~70 lbs and a moderate chewer, and this monster still gets regular play and is holding up well.

Great toys for aggressive chewers
Size: Medium/Large, Color: Turkey Day Drumstick - Large
These are great toys they last a while they are destroyed after a while but both dogs are aggressive chewers but they last about a year and a half. And they are go to toys they have one that is a shark mouth and they love it I have bought 4. (two of them the pups lost ).

Durable and Fun, Just Gets a Bit Rough
Size: Medium/Large, Color: Chopper - Large
This is a really good toy overall, especially if you have dogs that love to chew. My dogs were immediately into it—they play with it nonstop, toss it around, and stay entertained for a while, which I love. It definitely holds up better than most toys we’ve tried. The only reason I’m giving it 4 stars instead of 5 is because over time it does start to fray a bit and gets a little rough, especially with heavy chewing. It’s not completely indestructible, but it still lasts longer than a lot of other toys. Overall, still a great buy and I would recommend it if your dogs need something tough but fun!

Worthwhile!
Size: Medium/Large, Color: Turkey Day Drumstick - Large
I have a small dog with a really strong bite! Usually have to buy toys that are meant for bigger dogs. This has lasted us for what feels like forever. It does sound very heavy when dropped! My dog loves it though! Would definitely recommend!
