Great sleep sack at a great price

JazzJanuary 12, 2026✓ Verified purchase

I've purchased cotton sleep sacks from Amazon that seemed great, but shrunk 2 sizes in the dryer. Purchased yet another and the neck and arm holes were huge. Unsafe huge. I bought these as a last attempt before I went with a big known brand and I'm really glad I did. No massive arm and leg holes, great length, double zipper, and soft material. They did shrink in the dryer, but not too terribly. You can always hang dry them. Will purchase again! Read more

very functional and soft, great buy

stefannyOctober 29, 2025✓ Verified purchase

Great product to buy for yourself or a gift. I was gifted this brand and I bought a bigger size and even the long sleeve version. Very good quality, helps my baby stay warm without being too thick; great for babies who cant use a blanket yet. Baby is able to move around because there is enough room width wise. They have 2 way zipper so diaper changes are easy. The fabric is soft. Read more

Sleep Sacks are quality and function great when you are done swaddling

AdamSeptember 11, 2025✓ Verified purchase

These are working great for summer sleeping on warmer nights since they are lighter weight. We weren’t sure what to do once he started rolling over, and these were a great answer. The styles and cute and green is the best color. They keep the legs free enough to work for his hips but restricted enough that he isn’t kicking the top of the crib and waking up. The price is much better than competitors of similar quality. We’ve used them for months and through washer and dryer once a week they are still like new. Read more

My baby loves these

Anna StrengeDecember 10, 2025✓ Verified purchase

My baby loves these sleep sacks. Lightweight and love how the zipper goes from top to bottom and a second one from bottom to top. Makes it easy to change a diaper in the middle of the night. We have had this size since my baby was 4 months and now is 8 months and fits the best now. It seems to keep him warm through the night and during nap time. It’s soft and cozy. Washes well. We will definitely keep getting more of these. My baby sleeps so good in them. Read more

★★★★☆

Good quality. Slight critique on design.

BryOctober 14, 2025✓ Verified purchase

Overall I really like these sleep sacks and they are good quality. They provide just enough warmth for the baby. The zipper is good and I haven’t had problems with it. I also appreciate the two-way zipper feature. It’s a soft cotton sleep sack and it’s not too thick which is good. The only complaint I have is the neck of the sleep sack needs to be deeper. It often bunches up and I have to make sure he’s in it just right so it’s not pushing up against his chin. Read more

Perfect little sleep sack

Isabelle MastersonFebruary 1, 2026✓ Verified purchase

Perfect soft material, my little one feels very comfortable in it. The TOG level is perfect for our home temperature and have never had an issue where little one was too hot or cold. The material feels to be a perfect thickness for its TOG level and it also has a very good zipper. Read more

Perfect sleep sack for winter

AlyssaDecember 27, 2025✓ Verified purchase

Purchased the 18-24 for our 8 month to grow into. We have a smaller and lighter three price set he used from newborn until now. Those are still in great condition, he just outgrew them! We chose this for winter wear. Their page explains the difference between fabric thickness really well. This one is like a thin sleeping bag. The fabric is quality and exactly as advertised, zipper is sewn in well. He loves it! We also purchased the lighter weight set in a larger size for warmer weather. This is a great brand- we will continue to order sleep sacks from them and I will take a look at their other products as well. Read more
