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?

Lovely sleep sack set in gender neutral colors. Medium weight material for warmth but sleeveless to vent. Covered zipper for protection. Love the color combination and the material is good quality which will hold up with repeated use and is likely to survive being handed down which is a big plus for our family. Definitely a worthwhile purchase and a great value for the price.

I originally bought these because they were cheaper than any other sleep sacks I could find. When I received them I was pleasantly surprised to find them to be very thick, soft, and cozy but still nice and breathable. The 2 pack came with cute, simple designs. Will buy these again when it's time to size up!

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.

Some say it's too big but the more room to grow into it is perfect! My baby sleeps better in these sleep sacks than any we had before. I could even use one myself! So soft and comfortable. Will recommend these to everyone !

Very soft baby blanket sleeper. I love the soft feel to the inside of these. They are so soft which is important for soft baby skin. Very warm, perfect for cold days/nights. I wish i could find an adult blanket made of the soft, warm material. Perfect for babies.

These are 2-layer cotton with batting in the middle and in the northeast baby can wear them year round! My only gripe is that the size only goes up to 24 months (PLEASE offer these in 24-36 months or 2-3T).

These are awesome quality! They feel like a cozy cotton comforter. That perfect in between weight that you could use winter / spring / fall. Even summer if nights are cool. So happy with the 100% cotton baby items from Member's Mark!

The best sleep sack! I've purchased other ones but nothing compares to this one. It's nice and thick, keeps infant warm at night. Washed multiple times and it still holds its quality. Will likely buy another set as baby grows.

These nice soft sleep sacks. Wife likes them as she wanted the kind for our kid. These are good Cotton sacks. Pros- cotton, 2 pack, zipper, layered for added comfort. Cons- too soft and I feel we might see lint or bubbles after wash.
