Which says a lot because I hate all the other ones. It's very soft and very warm. Probably wouldn't work great if the temperature in your baby's room is stuffy, because it is WARM. But it's very breathable and made of good quality material. If fleece makes your baby sweaty, this is a good cool weather alternative. My baby sweats easily and I don't have any problems with this as long as I don't layer him in anything more than a onesie and socks. But he also gets cold easily and so I needed something warmer than those one layer cotton sleep sacks. This is a perfect compromise. It is sewn and designed well. It has a flap to cover the zipper head thing. I have to say, I wish i could get this adult size. It is very roomy and the snaps for sizing down are clever in their simplicity. ### ⭐⭐⭐⭐⭐ Our fave. *by N***N on Reviewed in the United States on August 10, 2017* Bought a few different sleep sacks. This one is our fave (mom and baby love). It's well made, cute, warm, baby loves the soft material it's covered in. The fit is great. We bought the large size for our 4 month old because he was +90th percentile in height and weight and it was fine. At first the arm holes were a little big, but at 5.5 months it's fine. The dual zipper is good for nighttime diaper changes if needed.We also have these other ones but this is our fave: woolino, halo baby cotton, 50/50 swaddle me ### ⭐⭐ I really wanted to like these as they are very soft and the design ... *by E***E on Reviewed in the United States on February 9, 2017* I really wanted to like these as they are very soft and the design is sweet however they are not ideal for older babies. My daughter is eighteen months and the large sacks barely fit her, they are often too warm, even in a NYC winter, the zipper frequently gets caught on the fabric and the main problem is that my daughter can easily unsnap the shoulder snaps and climb out of the sack in the night, which has happened numerous times. The design of these sacks could use some reworking. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/38806700-la-petite-chose-baby-sleeping-sack-adjustable-length-and-naturally](https://www.desertcart.jp/products/38806700-la-petite-chose-baby-sleeping-sack-adjustable-length-and-naturally) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-06*
