Comfortable swaddles

YvonneSeptember 6, 2025✓ Verified purchase

I’m really happy with this pack of 3 sleep sacks! They’re 0.5 TOG, so nice and lightweight—perfect for the warmer months and mild California fall weather. I love that my baby can grow into them, so they’ll last us longer than other sleep sacks I’ve tried. The fabric feels soft and breathable, and so far they’ve held up really well after several washes without shrinking or pilling. A great buy if you’re looking for comfy, lightweight sleep sacks for your little one Read more

Perfect Weight for Winter + Stays Soft After Washing

CustomerFebruary 28, 2026✓ Verified purchase

I bought the X-Large Rainbow for kiddo as winter nights entered the deep freeze. Finding a true 2.5 TOG sleep sack that isn't stiff or overly heavy can be tricky, but the Fiemol version hits the sweet spot for a 65°F–68°F nursery. Here is the breakdown of why this works for us: Warmth & Material: The cotton exterior is incredibly soft, and the filling doesn't "clump" after a trip through the dryer. It feels like a high-end duvet but remains breathable enough that my child doesn't wake up sweaty. The 2-Way Zipper (Life Changer): If you are still dealing with middle-of-the-night diaper changes, the bottom-up zipper is a must. It glides smoothly and has a protective fabric tab at the top so it doesn't chafe the baby’s chin. Sizing & Fit: The X-Large (18-24 Months) is generously sized. My toddler is on the taller side, and there is still plenty of "kick room" at the bottom without the neck opening being dangerously wide. Design: The rainbow print is vibrant and hasn't faded after several washes. It looks much more expensive than the actual price. One Small Tip: Because it is a 2.5 TOG, it is thick! I recommend drying it on a low-heat setting for a bit longer than your standard laundry to ensure the inner batting is completely dry. Pros: Very soft 100% cotton shell. Sturdy, snag-free 2-way zipper. True to size with room to grow. Cons: Takes a little longer to air dry due to the thickness (standard for 2.5 TOG). Read more

Nice, soft, warm!

Julianne K.March 7, 2026✓ Verified purchase

Loved using these sleep sacks! Easy to toss in the washer/dryer. They are mostly cotton and are soft and comfortable. We never had any safety issues with them. And kept our baby warm! I bought two or three different sizes and was happy with them each growing stage! Read more

Well

B.July 26, 2025✓ Verified purchase

Bought these to have on hand for when our grandchild sleeps over. They are lightweight- spring summer, however they would probably be fine in winter depending on your area. They are very well constructed and soft. The sleep sacks can be unzipped from the top or from the bottom for diaper changes. The top zipper has a protective flap to keep the zipper from irritating the child’s neck area. A warm water laundering didn’t seem to shrink them. I hung them to dry so I can’t speak to dryer shrinkage. I am very happy with the overall quality, attractive soft colors and price point. I would definitely would buy these again. Read more

Safe sleep for your little one

Honest Reviews by PageAugust 25, 2025✓ Verified purchase

The FIEMOL Baby Sleep Sack has been such a great addition to our bedtime routine. The fabric is soft and breathable, so my little one stays warm and comfortable without overheating. I love that it gives her room to wiggle while still keeping her safe—no loose blankets in the crib to worry about. The zipper is smooth and sturdy, and the protective flap at the top is a thoughtful detail that keeps it from rubbing on her chin. It’s also super convenient for late-night diaper changes since the design makes it quick and easy to zip up and down. Overall, this sleep sack is well-made, cozy, and provides peace of mind. Definitely a must-have for parents looking for both comfort and safety in their baby’s sleepwear. Read more

Very lightweight sleep sacks! Totally recommend.

Angela PadillaJune 29, 2025✓ Verified purchase

The media could not be loaded. I love these for my son! It is good quality, they have been washed a couple times and still look good. They did have a weird smell at first but after their first wash it went away! The zippers don’t get stuck and are easy. They are light weight which is really good for these summer nights! My son seems to be comfortable in them. I recommend if you’re looking for lightweight sleep sacks! Read more
