Best Baby Sleeping Bags of 2025

“I have been a fan of Burt's Bees for ages. Their sleep sacks are just perfect for my little ones. They fit wonderfully, are incredibly soft, and the designs are adorable! I especially appreciate that they don’t shrink in the wash.”

“I was torn between patterns, but I chose the Dinosaur design, which is just too cute! The organic cotton is softer than I imagined. With the freezing temperatures here, it keeps my son warm without overheating.”

“We received a lightweight small size as a gift, and it fits my baby better than others we've tried. It's so soft and offers plenty of room for kicking and rolling. We ended up purchasing two more in a medium size.”

"I absolutely love this sleeper! My 14-month-old kicks off the blanket and tosses around all night, waking up cold. I could never find these in stores in his size. It's very soft and cozy, with plenty of leg room. It seems a bit big, but that's even better since I won't have to worry about him outgrowing it before winter ends. I'm definitely planning to order more when he outgrows this one!"

"I ordered the 12-18 month size for my son and it’s huge! I can’t stop laughing at the size difference. The 6-9 month one he had was a little small, but this one is so soft that my 2.5-year-old can wear it! He will be using it for the next couple of years!"

"This sleep sack is incredibly soft and cozy, making it perfect for the upcoming winter in our area. However, I did notice that the arms and shoulders slid off my child because the material is somewhat slick, and the neck hole was a bit too wide. I was concerned he might get stuck during the night, so I decided to switch to another sleep sack for now. I’ll try this one again when he’s a bit bigger, but the sizing didn't quite match the typical 12-18 month sizes."

"I ordered some long sleeve ones because it's cold here and my heater is running non-stop. The sleep sack fits nicely, is soft to the touch, and has a light quilt feel. I bought two and would definitely order again when they get too small!"

"We absolutely love this sleeper! It keeps our daughter warm at night and is very soft and cute. My only issue is that there are little balls all over it now where the elastic is kind of falling apart. I should have air-dried it instead of using the dryer. Otherwise, it’s a 10/10! I’ve since bought more for our son, and they’ve held up much better!"

"This sleep sack is perfect! It's lightweight but warm, making it easy to get on even if my baby is squirming or already asleep. I highly recommend it!"

“I found these sleep sacks perfect for transitioning from a swaddle! The lightweight 100% cotton material is not only soft but also breathable, making it super comfortable for my baby. The 2-way zipper is a huge plus for diaper changes, and the 0.5 TOG is ideal for warmer weather. Plus, the green design is adorable! I highly recommend these as a newborn essential!”

“I’ve been really pleased with these sleep sacks. They’re lightweight and have plenty of leg room for my tall 4-month-old. I noticed some comments about zipper issues, but I just zip it a bit slowly and it works fine. I might go for TOG 1.0 next time for a little more warmth, but these are great as they are. However, I did notice some extra threads coming out after a couple of months, although it hasn't affected their function.”

“I bought these for my brand new granddaughter, and they have been a huge help. Her little feet stay warm in the morning, and no matter how much she moves at night, she never gets tangled in it. The material is a bit on the thin side, but that’s perfect because we don’t want her to sweat. Overall, a great product!”

“I found this swaddle to be the absolute best for my baby who likes her hands by her head. The first night we used it, she slept great! It's super easy to put on, and I don't have to worry about any Velcro coming undone during the night.”

“As a new mom, I appreciate how this swaddle keeps my baby secure and safe while sleeping. The arms-up position seems to be the most comfortable for her, resembling the position in the womb. I plan to use these throughout her growth.”

“This sack has been a life saver for my baby and me. It's incredibly comfy, soft, and fits just right. It definitely helps my baby stay asleep longer since she can't un-swaddle herself. The quality is great, and it’s easy to wash.”

"I was pleasantly surprised by the great cost and amazing comfort! This soft quality sack has helped my baby girl sleep SO well. It's the perfect warmth for her. I'm definitely buying more since it makes life easier without needing a blanket!"

"This is my second set of baby sleepy sacks. I initially received one as a hand-me-down and after trying various other brands, I found myself returning to this one. The super soft material and safety snap across the zipper gives me peace of mind. They may look huge at first, but my daughter grows into them comfortably!"

"These sleepy sacks are super cute and lightweight, making them ideal for summer! I appreciate the large sizing range as I got them in size 3-9 months for my daughter."

"My 8-month-old loves this sleep sack! It fits really well with plenty of growing room available. It's soft and keeps him warm and snug all night. It's held up great with regular washing. I wish I had found this sooner!"

"I had some doubts due to the price, but this is hands down the best sleep sack I’ve tried. The zipper quality is excellent, and the fact that it opens from the bottom makes late-night changes much easier. The shoulder snaps are a huge time-saver for putting it on my baby."

"I absolutely love these sleep sacks! I repurchased as my son got older. He was always warm and snug, and they are easy to wash and use. The shoulder snaps plus the zipper make it so convenient. I can't recommend them enough!"

"I purchased these after getting my grandson for a few days. I needed them, like, NOW! He calmed right down as soon as he was wrapped like a burrito. The quality is wonderful, soft and sturdy, and I specifically looked for swaddlers that were up to 6 months, and that's exactly what I got."

"The KeaBabies organic swaddle sacks have truly been a lifesaver for me! The material is incredibly soft and perfect for my baby's delicate skin. I appreciate the excellent quality, and they wash well without fading. My baby stays snug and doesn’t wriggle out, which means better sleep for both of us."

"I had struggles getting my 1.5-month-old baby to sleep longer stretches, but this Keababies swaddle has been a game changer. Now my baby sleeps through the night and takes longer naps during the day. The cotton material and quality are awesome, and the fit is great. I would definitely rebuy it for his next age group!"

"I absolutely love this sleep sack! Kyte brand is fantastic with wonderful quality. The zippers are smooth and it fits true to size, keeping my baby comfortable in different temperatures."

"I've been using this sleep sack for my twins and they adore it! The fabric is incredibly soft and breathable, making it easy during those long nights. Although it's a bit on the expensive side, it's worth every penny!"

"This is my third Kyte baby sleep sack! My kids find them so cozy and warm. They wash easily and the quality is amazing. I highly recommend these for any parent!"

"I have been using these sleep sacks since my son transitioned from swaddling, and we keep buying the next size as he grows. The quality is fantastic and the value is unbeatable. They're soft, lightweight, feature a double zipper, and come in adorable patterns! We've used them through all seasons in New England and they work perfectly!"

"After trying numerous sleep sacks, I can confidently say these are my favorite! The breathable material keeps my little guy warm without overheating. They hold up well after multiple washes, and I appreciate the roomy design that allows him to move around while sleeping."

"These sleep sacks are simply the best! My daughter wears one every night, and even with frequent washing due to diaper leaks, they look brand new. The zippers are easy to use, and while they do run a bit large, they are soft and practical for layering."
