What experts liked

Zen products are toxin free. It is super easy to zip and just glides right along. The sack has a double zipper giving you the option to zip and unzip from the top/side or the bottom. The material is also moisture wicking.
- MamatheFox
The weighted bag is filled with non-toxic beads and won’t prevent your baby from moving around or even rolling over. (It’s also perfectly fine for the washing machine.)
- Baby List
It has adjustable shoulder straps (for a better fit) and two-way zippers (for diaper changes).
- Wear Love Wanders
The Nested Bean sleep sack is adorable, cozy, and the weighted bean on the front is cute and just right, not too heavy at all. The fabric is soft and the design is cute. It feels high quality to me.
- Breast Feeding Needs
Full side zippers make for easy diaper changes at night and shoulder snaps allow the Zen Sack to grow with your baby.
- Lucie's List
Has a lightly-weighted pad on the chest that mimics the feel of your hand to give baby a little extra comfort during the night. A two-way zipper along the side and adjustable shoulder straps that makes it take longer to outgrow.
- Good Housekeeping
It comes with double zippers to ease diaper changes. It has adjustable straps so your baby can grow with it. It is sleeveless to ensure your baby maintains a healthy temperature.
- Mom Loves Best
Super easy to use. A two-way zipper means that you can undo just a baby’s legs for middle of the night diaper changes really easily. And two rows of snaps on the shoulders means it grows with your baby!
- Much Most Darling

What experts didn't like

Many report longer sleep periods with the weighted sack, but as with anything, some don’t notice any difference in their child’s sleep.
- Lucie's List
It’s only available in sizes up to 15 months. It costs more than other sleep sacks. The chest weight is ineffective once baby can turn over to its stomach.

An Overview On Baby Sleep Sacks

While swaddling blankets wrap around babies to keep them feeling snug and secure, they usually loosen. Worse still, if they are wrapped too tightly, it limits the baby’s mobility. Sleep sacks (also called sleep bags) are made of thicker material, and they provide that snuggly feeling without limiting mobility. They are basically like wearable blankets, with zippers for when diaper changes are needed.

Experts feel that sleeping sacks can help babies snooze longer, and that makes parents, caregivers, babies and their siblings happier. Some of these outfits have sleeves, while others are sleeveless and fit right over whatever the baby is already wearing. When the weather is cool, a full-sleeved option will keep them warmer.

Look for soft, natural materials like 100% cotton when shopping for baby sleep sacks. Also read about where the zipper is located; some zipper from the bottom up. You don’t want to be scrambling around when baby needs a clean diaper.

The Baby Sleep Sack Buying Guide

  • Choose a sleep sack that is appropriate for your baby’s weight and size.
  • The sack should fit comfortably around the baby’s neck, shoulders and torso, and it should not be tight.
  • The sleep sack’s neck opening should not be too big; you wouldn’t want your baby to slip down inside.
  • The arm holes on a sleep sack should not be big enough to allow the baby to get their hands inside the body of the outfit.
