Weighted across 10 criteria

CURATEIQ

TrustScore breakdown

85 /100

We take what's most important for a product to determine the TrustScore. Here's our research:

Safe-Sleep Design Compliance 91

The sack is explicitly non-weighted and stated to comply with AAP recommendations, uses a two-way zipper rather than ties or cords, and a related SwaddleDesigns sleep sack has earned IHDI Hip Healthy recognition, though no TOG rating is published for this specific sleeveless muslin item.

Fiber Content & Origin 85

The garment is stated to be 100% cotton muslin with an open-weave design aimed at reducing overheating, but no certifying body or organic status is claimed for this specific product and country of manufacture is not stated for it.

Textile Certification 78

No GOTS or OEKO-TEX certification is named for this muslin sack; the fabric is described only as 100% cotton muslin with no certifying body or standard attached to the finished garment.

Recall History 97

We queried the CPSC recall database directly — nearly 10,000 records spanning 1973 to 2026 — and SwaddleDesigns appears nowhere, in any role. Control terms like diaper, crib and stroller all return matches, confirming the search actually covers this product class.

Sleepwear Flammability Compliance 78

This sack is sold in sizes up to 12-18 months, so the under-9-months swaddle exemption from 16 CFR 1615/1616 does not clearly cover the full size range, and no compliance route or exemption basis is stated anywhere for the garment.

Certification Credibility 84

The brand names an 'Organic' collection and cites an award for a different product, but no certifying body, standard name, or certificate number is given for this muslin sack, and it isn't part of the organic line.

Chemical Finish Avoidance 84

The fabric is breathable, open-weave, preshrunk and machine washable, with no wrinkle-resistant, non-iron or stain/water-repellent claims anywhere, but there is also no explicit brand statement ruling out such finishes.

Transparency & Support 84

Manufacturing is described only partially — some products sewn in Seattle alongside unnamed international factories — with no full materials list and no country of origin stated specifically for this sack; warranty carries a stated exclusion for improper washing/handling.

Fastener & Neck-Opening Safety 90

The sack has a soft fabric zipper guard built in specifically to keep the zipper from touching the baby's skin, though no neck-opening measurement or head-pass testing is stated.

Hardware & Print Safety 77

This sack uses a zipper rather than snaps or prints, and there is no nickel-free, lead-free or print-method disclosure at all for its hardware.

Customer Stories

Sentiment Summary

Customers describe the sleep sack as soft, lightweight, and easy to get baby in and out of, with the two-way zipper making diaper changes simple.
Several reviewers mention their baby sleeps better and for longer stretches while wearing it, especially in warm weather compared to footed pajamas.
Reviewers who worried about durability after reading complaints about similar products say this sack has stayed soft and held up well through repeated washes, with the zipper still working smoothly.
Some reviewers note the fit runs generous, finding a size a bit big at the lower end of its range or roomy with growing space for a taller baby at the upper end.

This sleep sack is great! Soft and light, easy to get baby in and out of and makes diaper changes easy with the dual direction zipper!

We purchased this sleep sack for our daughter for the summer nights. It has worked so well we purchased a second sack. My daughter has always seemed to "run warm". I found this item and we have loved it. She consistently sleeps better in this, we get longer stretches from her when she is in the sleep sack vs footed pjs (even the thin ones). It was a little big for her at 6 month (she's about 50th percentiles). I had initially purchased for summer, but we will probably continue to use this during the winter months with a long sleeved onesie under since our home temperature is fairly consistent through the year.

I was searching for a lightweight muslin sleep sack for my little one. I combed through reviews, and the common theme seemed to be, "It fell apart after a few washes." I took a chance with this brand, and I've been very happy it. It's soft yet well made. It has lasted through several washes, and the double zipper still works smoothly. I ordered the 6-12 month size for my tall 10-month-old (30") and it fits well with plenty of room to grow.
