Wonderful sleep sacks! They are just the right thickness and super soft. Best part is the great price. You can't beat it!

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 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.

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!

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.

Can’t beat the value of these sleep sacks which means you can afford to buy multiples. The material is 100% organic cotton and very soft and comfortable. The two way zipper is the best. I will be buying some for baby gifts as they would make a great shower gift.

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!

The members mark sleep sacks are hands down the best ones, especially for the price. They are on the thinner side, but they feel a little heavier and are SO soft. I love the sleeveless ones, perfect for summer. I feel like having the arms open, my baby gets cool air, but yet she feels cozy and warm. It also has two zippers, a top and bottom, which is convenient for diaper changes in the middle of the night.

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!

The 2pc sleep sacks from member’s mark are soft, high quality, and seem comfortable. My daughter normally uses a higher end more expensive brand sleep sack but we got to try these out. The fabric is soft and a good weight. Not too heavy but not too light. The zipper works well. She slept well in it!
