We did find the fabric to be a bit thin-if we were to compare it to adult blankets, we'd say it is more like a top sheet than a quilt, so it’s best suited for warmer weather. We appreciated how lightweight the 100 percent cotton material is, which makes it great for summer and very soft against the skin. The Primary Muslin Sleep Sack is a high-quality sleep sack that comes in vibrant colors and patterns little ones (and their parents) are sure to love. Key Specs: Material: Polyester microfleece | Age Range: 0 to 6 months old | Machine Washable: Yes | TOG: 3.0 There are several colors and patterns to choose from, though sizing only goes up to roughly 6 months old, or 18 pounds.

We’re impressed by the value of the Halo Sleep Sack Swaddle for $30, you get a swaddle and a sleep sack that will help you transition your little one between the two. In our test, it also held up well in the wash and didn’t pill or get rough. Plus, there are no tags, metal, or anything that would irritate the baby. Made from plush 100% polyester microfleece, this sleep sack is warm and cozy, but it’s also designed to wick away moisture, so your baby doesn’t overheat.

When your baby becomes more mobile and shows signs of rolling over, transition them to a sleep sack, taking one arm out of the swaddle at a time. To swaddle, simply wrap the wings around the baby and use the hook and loop closures to secure them. A silky instruction diagram is conveniently placed on the inside flap of the swaddle wing for you to refer to (and it won’t irritate the baby). The Halo Sleep Sack Swaddle pulls double duty: It’s a cozy swaddle for infants, then it helps you transition your baby’s arms out of the sack when they start to roll. We also had a board-certified pediatrician from our Review Board review this article for medical accuracy and integrity surrounding sleep sacks, the safety of these products, and how to evaluate them.

We then put the top 20 sleep sacks to the test in the real world with the help of a team of 11 staff testers and their little ones, who used the sleep sacks in their homes, washed them several times, and evaluated their quality, durability, ease of use, value, and comfort. With these factors in mind, we talked to experts and conducted research to find the best sleep sacks for babies available on the market. To keep your baby warm and comfy, look for a sleep sack in a material that's appropriate for the temperature in your baby's room and has the type of closure (snaps, zippers, or fabric fasteners) that is easiest for you to fumble with during a late-night diaper change. In our experience, sleep sacks belong on the “must-have” list of baby supplies for all new parents because they keep babies warm while also following the American Academy of Pediatrics' safe sleep guidelines, which advises against loose bedding near infants. Also known as a wearable blanket, a sleep sack keeps your little one's body and legs secure and provides that same cocoon-like feel of a swaddle but gives them more freedom to move their arms and explore their space. When your baby starts to show signs of rolling over from their back to their stomach, it’s time to transition them from a swaddle to a sleep sack.
