Great product!

Rebekah ColchinOctober 16, 2025✓ Verified purchase

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. Read more

Obsessed!

Jamie RossOctober 13, 2025✓ Verified purchase

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! Read more

Really Soft and Durable.

OdalisOctober 27, 2025✓ Verified purchase

The Sweet Dolphin Sleeping Pack is soft, safe, easy to clean, and budget-friendly — truly an amazing find. It’s made from 100% cotton that feels gentle and smooth — perfect for my baby’s sensitive skin. The 2-way zipper is a thoughtful feature — it makes diaper changes at night so much easier. The sack also washes very well; even after multiple washes, it stays soft, holds its shape, and the zipper continues to glide smoothly. It’s clear that attention to detail was put into both the product and its packaging. Most importantly, my baby sleeps soundly and happily in it, which says it all! Read more

Thin and roomy

Angelica HernandezJanuary 4, 2026✓ Verified purchase

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. Read more

Great quality sleep sack – thick, soft, and cozy!

AliaJune 23, 2025✓ Verified purchase

The media could not be loaded. This is my second time ordering a sleep sack while searching for the best one for my baby, and so far, this one is the better option compared to the previous brand I tried. The material is excellent—thick, high-quality cotton that feels soft and breathable, perfect for cooler nights. It feels durable and well-made, which gives me peace of mind. The only reason I’m giving 4 stars instead of 5 is because the sizing runs a bit big, so it looks a little roomy on my baby right now. However, I actually don’t mind too much since it leaves room to grow, and she still sleeps comfortably in it. Overall, I’m very happy with this sleep sack and would definitely consider ordering again! Read more

Baby Approved

Joe MagnottaJanuary 4, 2026✓ Verified purchase

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! 💕😴 Read more
