These are great, very soft and comfy. They are 100 percent cotton. And the interior lining is all polyester. Would recommend, it has zippers at both ends for easy diaper changes. The size is for 6-12 months, they are very long and roomy. Could be a good fit for quite a while. Easily keeps little feet warm.

Exactly What We Needed for Cold Nights! This sleep sack is a game-changer for our baby’s sleep routine! The material is super soft and thick without being too heavy or stiff — perfect for cooler nights when you don’t want to worry about blankets. Our little one stays warm and cozy all night, and we’ve definitely noticed longer, more restful sleep stretches since using it. The zipper is high quality and zips from the bottom too, which makes middle-of-the-night diaper changes so much easier. We also love that it washes well — still just as fluffy and soft after several washes with no pilling or shrinking. Highly recommend if you’re looking for a warm, safe, and snuggly option for your baby to sleep in this winter or even if you sleep with your room cold!

I’ve used a few different sleep sacks, but this one really stands out because of its roomy yet secure fit. My 7-month-old has plenty of space to move their legs while still feeling snug up top. The 6–12M size fits perfectly with a little room to grow, and I appreciate that it doesn’t ride up or twist during sleep.Washing is easy too—holds up well in the wash with no shrinking or pilling. The fabric stays soft even after multiple washes, which is a huge win.

These sleep sacks are so cute! I love that they come in a pack of two. I appreciate the gender neutral coloring while still being cute. They are super soft and thick, which will be nice on cold nights! I like that they are made out of cotton (with polyester filling) instead of fleece. BUT! My favorite part is the double zipper for middle of the night diaper changes! That’s a game changer! I’m so excited to use these for my baby!

My baby never sleeps through the night but with these I found that baby sleeps in longer increments. Soft and comfortable keeps baby warm and you don’t have to worry about checking if baby is still covered throughout the night. Still easy to access diaper for changes.

These sleep sacks are great! They are 100% cotton on the outside with some polyester fill that makes them heavier than the current ones I’m using. I like that they have a two-way zipper that goes straight down the front versus the ones I have now only have a one-way zipper and go down the side - I struggle with that zipper. These are much easier to zip up a sleeping baby. Cute colors too.

WOW. I used to use to use little potato sack covers when my son was a baby. But these are definitely a 2025 version. Soft and pillowish from the double lining, and they are ever so slightly insulated, but not overly warm or heavy. I like to use them for my daughters long sleep sessions. Gives her that warm, cozy feeling, no movement restrictions, and lets her feet roam free. The two way zipper closure is amazing so I don’t have to take her whole body out of it when it’s time for a diaper change. The button fasten at the top cover is the zipper so she doesn’t play with it or it doesn’t hit her face. Also a good travel piece to take when you’re on the go in case it gets a little chillier than expected. These can definitely be used year round.

Cute pink and light purple sleep sacks. Haven’t used yet as baby hasn’t arrived yet but the material is very soft and has no tags to irritate . Fabric is a little thick but not too heavy. Easy to put on and take off with front zipper and one snap. As always, members mark has great value in their products.

These worked like a charm, given that we like having the house cooler than normal, not only do they provide the warmth but have help soothe out little one at night. We've noticed they've been sleepijg through the entire night without any fussiness or middle of the night waking up. They come in a pack of 2 and there are a few different color options. Highly recommend for someone looking for some economical sleep sacks, since they'll outgrow them quickly.

My baby absolutely loves these sleep sacks! We used the size below this when they were smaller and were definitely getting the next size up when he was ready! It lets him stay warm at night without using anything inside the crib.
