Thicker than the average sleep sack, soft and high quality. The sack itself is cotton and the filling is made from polyester, so it has the feel of a quilt. It has a two way zipper that makes changing diapers much easier. Not tight but it has a little bit of weight that may help with startle/moro reflex?

I was nervous about the sleep sacks in the summer in TX but the were the perfect weight for my little one. She did not get hot we keep the house at about 73 degrees at night. They seem to hold up well on the washer.

I'm really happy with this navy 2-piece baby sleep sack set! The fabric is super soft and cozy, perfect for keeping baby warm without getting too hot. The zipper makes it easy to use, even during those middle-of-the-night changes. I love the simple navy color it looks so cute and goes with everything. They wash well and still feel just as soft. Great quality and such a comfy bedtime staple!

Love these! Mom of 5 here and I actually got these myself before I received them as a promotion. So I know they have worn well through many washes. I really like the thickness for warmth but yet light at the same time so I don't feel baby is weighed down at all. Double zipper too for the win

These sleep sacks are a nice thickness, would say they are the inbetween TOG, so for rooma that are not too hot or cold. It is a quilted blanket witha cotton feel, not bamboo. Still very soft. Has nice zippers as well and is nice and long for taller kids.

Beautiful set; feature two sleep sacks with arm holes. Soft quilt like material with double zipper, perfect for those late night diaper changes. Zipper comes with a snap top cover to ensure no clipping on the zipper. I would say these are more 3+ plus with compareable size of a true newborn

Perfect Sleep Sack for My Little One! I absolutely love this sleep sack! The material feels soft and cozy, keeping my baby warm all night without overheating. The zipper design makes nighttime diaper changes super easy, and I feel much safer using this than a blanket. My baby sleeps so peacefully in it, and I've noticed fewer wake-ups since we started using it. Definitely worth the purchase — I'll be buying another in the next size up!

These sleepers are great for my baby who hates blankets!! (Also her daycare requires something like this). The colors are gorgeous and I really love the tan one with its muted stripes and flecked coloring. Just absolutely gorgeous. These are a great safe option for baby to sleep soundly without a bunch of blankets. I also really love that there is a double zipper so changing is super easy. I got the 18 to 24 month size and my baby is pretty much in 24 months in all clothes. These have a ton of room. I put my hand by where her feet stop and there is still at least another 4 to 5 inches of room so these will grow with her and keep her comfortable all the way. Very happy!

These are excellent high quality thick sleeveless sleep sacks. Love that they're double layered for the added warmth and sleeveless so you still have fleece footed long sleeve pj underneath for added warmth without overheating the baby. Very soft and I like the double zipper. They're also very long and roomy, way bigger than the average 18-24 month sleep sack so great for lengthy babies.

These infant sleep sacks are really well made. Thick, soft, and comfortable. Colors are very neutral, but great. The only reason I gave it three starts was because they are huge!! I received the 12-18 months and I could probably fit in it. They run really big. But overall, they are a good product if your baby likes to be snuggled at night!
