    • Great product!
Color: Grey Size: 6-12 Months
I bought this for my 5 month old as we are going into cooler weather. I am happy with their quality of fabric and two way zipper, makes it easy for night diaper changes! They are really long but fit comfortably at the arms and neck area. He will definitely be able to wear these for the next 6 months! He now knows it is nap/sleepy time when I put him in this and sleeps great in it! Lightweight that he won’t get over heated but warm enough he won’t get chilled. ... show more

    • Obsessed!
Obsessed with this sleep sack, I love the fabric, its thick soft and light weight at the same time. Love the color wave, texture, and zipper quality. It’s the perfect size and length and very durable. I’ve washed this more times than I can count and the quality has remained the same. 10/10 would recommend! ... show more

    • Thin and roomy
Color: Grey Size: 0-6 Months
I like that it has a double zipper and has a lot of room for the baby to kick. It is long so be aware of that. It is thin compared to other ones but it is nice and breathable, not heavy.

Color: Grey Size: 0-6 Months
We absolutely love these baby sleep sacks! Our baby slept in a sleep sack from the moment we brought her home from the hospital, and these fit her perfectly. She’s worn them every single night for the past 4 months, and they’ve held up wonderfully. They’re comfortable, well-made, and make bedtime so easy. Knowing she’s cozy and secure gives us great peace of mind. We’ve been so happy with them that we’ll definitely be purchasing the next size up soon. Highly recommend to any parents looking for reliable, high-quality sleep sacks! 💕😴 ... show more
