Review: Love the quilt-like design and quality! - This sleep sack is great for a chilly room. Our little one’s room seems to stay about 5 degrees colder than the rest of the house so we were looking for a warmer sleep sack for the winter months. She has been warm and cozy, no matter what the temp is in her room. It’s a nice quality product that is soft, thick, and quilt like (it has a nice weight to it). It did shrink about an inch with the initial wash, which I was a bit bummed about because it just means she will grow out of it that much sooner, so I would order a little bigger than you think.
Review: Warm & Cozy Baby - My baby kept waking up two to three times in the night almost every night as it has started getting cooler. I was so exhausted that I put her in bed with my husband and I but we both don’t really want that as we both sleep hard and a move a lot in our sleep. But she was sleeping solid when she was in bed with us and I realized that she wasn’t warm enough in her other sleep sack. Did some research and came across this sleep sack that was a TOG 2.5 as we keep our house around 67-68 degrees at night. I sized up (she was about to be 7 months old and I got the 12-18 month size) because I wanted this to last her a long time. When I received it I was shocked at how long it was! Haha but kids do grow. After the first wash it seemed to have shrank quit a bit. Fortunately I had sized up. She’s currently 7 months old and 27 inches long and it fits but I don’t know if it’ll really last her beyond 12 months. Fortunately this product isn’t over priced so it won’t be costly to buy the next size up when needed. But I was trying to avoid that. Overall, great product! Baby sleeps through the night now and doesn’t wake up all the time anymore! She stays warm and everyone in our house gets sleep. Definitely recommend!

### ⭐⭐⭐⭐⭐ Cozy sleep sack
*by A***R on October 10, 2025*

Absolutely love this sleep sack! We needed a thicker sleep sack since we keep the house cold. It’s comfy, soft and keeps my son warm. We’ve bought every size since he was born and I’m bummed they don’t make anything beyond 24 months. Easy to get on and off, zipper cover at the top under their chin, and I like how it flares out at the bottom leaving plenty of room for him to move. He would size out of it early which is a bummer because of the length.
