Cute, good size, very VERY thin
4 out of 5 stars
Cute, good size, very VERY thin
This is a cute sleep sack with soft material that’s a great size and fits my 18month old with room to spare. The designs are cute and I got 2 different designs (one solid color and one plant design), both of which are simple, minimalistic and neutral colors that are great for any gender. The material feels nice and the quality seems decent, but my biggest problem is that the material is SO thin, as thin as a sheet. So I guess it’s definitely lightweight, but a little too much for me. Normally I use sleeps sacks to provide warmth, but this one really doesn’t provide any warmth. I think personally this would only be useful for places where it’s overly hot and you just need something lightweight to provide a thin layer. For us it’s usually cold at night, so I really don’t think I will ever be able to use this unless it’s summer or super hot.

    Love this sleep sack! It was honestly my “back up” until my preferred sleep sacks arrived but this product is better than my first choice sleep sack! My baby is very warm body and then with the warmer temps I wanted something a light weight and easy/quick to put on. The product is just enough for him to be covered and feel comfort but so light weight that I’m not worried about him overheating! Def good value for money !

    My daughter loves this sleep sack, she had no problem transitioning from her old one which was smaller and had a higher TOG for winter. It’s super soft and light weight for the summer months, the zipper works great, and I haven't had any issue with shrinkage in the wash. Super great quality for the price! Highly recommend!

    This sleep sack is perfect for my son. He loves having a sleep sack, but he runs hot. I tried other brands, but he would wake up sweating. This sleep sack is light weight and keeps him comfortable. It is about the thickness of a top sheet. I liked this so much, I ordered another one!

    My baby cannot go without a swaddle! I know they say once your baby learns to roll completely on their own to stop swaddling them but my baby is so quick to know when I lay her down. If you’re worried about your babies legs not being able to wiggle around, go up a ONE size ! I wouldn’t recommend too big of a size up, you want your baby comfortably. I did size up and still put my baby in here for naps, bed time and she still have plenty of space and can roll freely, currently 6 months

    Very thin but perfect for babies during summer. We have AC so I didnt want my baby to be cold, it was perfect. The design is very pretty and quality is fine. I washed it and put it directly in the dryer, no problem.

    Amazon Vine Customer Review of Free Product( What's this? )
    The Baby Sleep Sack Unisex 0.5 TOG is a parent's dream come true.

    Durability is top-notch with excellent stitching and finishing. The added zipper guard ensures safety, and the 5-way zipper makes diaper changes a breeze without disturbing sleep.

    Perfect for summer, the light, breathable fabric is gentle on baby's skin. The two-way zipper design is a gamechanger for quick changes.

    Although the fabric is thin, it's stylish and practical, fitting toddlers from 18-24 months or small 2-3 year olds.

    This sleep sack is a lifesaver for sleep schedules. The soft blend keeps baby cozy without overheating, and the built-in swaddle provides snug comfort. Parents love the roomy bottom for movement.

    A few minor quirks like occasional zipper sticking and slightly narrow armholes were noted, but the overall convenience and comfort outweigh these.

    In short, this sleep sack is a must-have for modern sleep training. Affordable, safe, and practical—it's a winner for healthy sleep habits. Highly recommended for new parents seeking a reliable and cozy sleep solution.
