Weighted across 10 criteria

CURATEIQ

TrustScore breakdown

89 /100

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

Safe-Sleep Design Compliance 84

A forum discussion describes the small armhole and neck-hole geometry preventing the sack riding up over the face, but the brand does not itself state the design is unweighted or detail neck/armhole dimensions for this product, and no TOG-to-room-temperature guidance is given here.

Fiber Content & Origin 90

The core fiber is named as TENCEL™ Lyocell, a named material with known hydrophilic, moisture-wicking properties, but no exact fiber percentage breakdown is published for this item.

Textile Certification 92

The sleep bag's 94% TENCEL Lyocell and 6% spandex knit is, by the brand's account, covered by OEKO-TEX STANDARD 100 certificate SH025199672, which is valid at product class I for baby sleep bags and swaddles, but the certificate's lyocell knit entry lists white and yarn-dyed fabric rather than printed.

Recall History 92

We queried the CPSC recall registry's complete corpus and found one 2022 recall filed against this brand, for children's sleepwear flammability violations — a different product category than this sleep bag. The brand also publishes a safety and quality commitment page. The recall is CPSC #22-165, announced in June 2022.

Sleepwear Flammability Compliance 89

The sleep bag is meant to be worn over a bodysuit or sleeper, which CPSC staff treat as general clothing rather than sleepwear, and it is tested to the general clothing flammability standard, 16 CFR Part 1610, with the brand stating that no flame-retardant finish is applied. That classification rests on the brand's dressing guidance.

Certification Credibility 95

The brand names OEKO-TEX STANDARD 100 certificate SH025199672 for the sleep bag, and the OEKO-TEX Label Check shows it as valid at product class I for baby articles including sleep bags and swaddles, though its lyocell knit entry lists white and yarn-dyed fabric rather than printed.

Chemical Finish Avoidance 92

Loulou Lollipop states that no wrinkle-resistant, easy-care, water- or stain-repellent, antimicrobial or flame-retardant finish is applied to the sleep bag, whose fabric is stated to be OEKO-TEX Standard 100 certified. The certificate the brand names for it, SH025199672, lists lyocell knit as white and yarn-dyed rather than printed.

Transparency & Support 85

The warranty covers manufacturing defects only, excluding normal wear and improper use, with care-instruction compliance required to maintain coverage — no concrete remedy process, timeframe or spare-parts route is spelled out.

Fastener & Neck-Opening Safety 84

A forum post and a two-way zipper review describe armhole/neck sizing and zipper function for this fabric-and-construction family, but the brand does not itself publish zip-guard details or exact neck-opening measurements for this product.

Hardware & Print Safety 91

The sleep bag's two-way zipper is a YKK zipper stated to be nickel- and lead-free, and the sleep bag's prints are made by digital or reactive dye printing with AZO-free dyes on fabric stated to be OEKO-TEX Standard 100 certified.

A closer look

FAQs

Why TENCEL™ for this sleep bag instead of muslin?

TENCEL™ Lyocell is a wood-pulp fiber spun in a closed-loop process. It pulls moisture off the skin quickly and stays soft and keeps its look through repeated washing, so Loulou Lollipop uses it in its year-round 1.0 and 2.5 TOG sleep bags, the ones that get washed most. For the lightest warm-weather layers, you might want Loulou Lollipop's products made with Tanboocel® Bamboo Viscose — like the 0.5 TOG sleep bags, swaddles, and crib sheets.

What TOG rating should my baby wear?

Match the TOG to the room. 0.5 TOG for 75–81°F. 1.0 TOG for 70–75°F, the most common nursery temperature in Canada. 2.5 TOG for 61–68°F cold nurseries. A nursery thermometer removes the guesswork.

What should baby wear under a 1.0 TOG sleep sack?

A short-sleeve bodysuit at the top end of the range (73–75°F), a long-sleeve bodysuit in the middle (70–73°F), or a sleeper at the cool end (70°F). The TOG rating gives you the main warmth; what your baby wears underneath lets you fine-tune from there.

My baby loves this sleep sack! It’s so soft and very easy to use. It also washes well in the machine.
CashB
I love these sleepsacks, I have two for my son. They are so soft and comfy.
Steen
Love the fabric! It’s so gentle for baby. It’s a good weight too. I only wish it didn’t snag.
Kari
This sleep sack is very soft and cozy. Unfortunately my little one kicks her feet so much it pulls the inside fabric and makes it tight around the back of her neck.
BabyAmom
After one wash it looks very pilled, faded and like it has been used for years :( I am so sad as before it was washed it was a beautiful looking garnet. I washed in cold, delicate cycle with a gentle baby detergent.
