Certificaciones

    • OEKO-TEX Certified

    Certified by OEKO-TEX (Standard 100)

    OEKO-TEX STANDARD 100 certifies that every component of a textile item has been lab-tested and found free of harmful substances above set limits.

    What it checks

    • Testing of yarn, fabric, buttons, and other accessories against a list of over 1,000 regulated substances
    • Stricter chemical limits for products with more intensive skin contact, including a dedicated infant/toddler product class
    • Compliance with chemical regulations such as REACH, CPSIA, and the ECHA-SVHC candidate list
    • Annual review of substance limit values and one-year validity per certificate

    What it does not cover It tests for chemical residues only and does not certify general product safety features like choking hazards, flammability, or mechanical construction.

    This certification is held by the brand or manufacturer, not by Birch. We show it because the brand states it for this product. Summarised from the certifying body's own page.

CURATEIQ

TrustScore breakdown

88 /100

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

Safe-Sleep Design Compliance 91

The sleep sack is rated TOG 1 with a published dressing guide matching temperature ranges, has a two-way zip rather than ties, zero-irritation neck and arm construction, and a teardrop-shaped bottom for hip-healthy fit. One parent review reports legs getting tangled due to fabric stretch.

Fiber Content & Origin 91

The fabric is disclosed precisely as 67.5% Lenzing Tencel, 27.5% Modal, 5% Elastane, sourced from eucalyptus and beech trees, and is breathable and moisture-wicking for extended wear.

Textile Certification 92

OEKO-TEX certification is named directly for the CloudBlend fabric used in this sleep sack, and a third-party listing repeats the same certification claim for this product line.

Recall History 97

We queried the CPSC recall database covering 1973-2026 and found no record naming WildBird in any role. The corpus was confirmed to cover comparable product classes like strollers and cribs, so the clean result reflects a genuinely clean history.

Sleepwear Flammability Compliance 76

This sleep sack is presented as a wearable blanket rather than sleepwear, and no flammability compliance route, snug fit or flame-retardant treatment, is stated for it, while reviews describe cozy, warm use at bedtime.

Certification Credibility 92

OEKO-TEX certification is named for the CloudBlend fabric used in this sleep sack, and an independent reviewer repeats the same certification and non-toxic claim without adding its own testing.

Chemical Finish Avoidance 78

The fabric and care instructions describe a stretchy, moisture-wicking knit with no mention of wrinkle-resistant, non-iron, or water/stain-repellent finishes, but the brand does not explicitly state the sleep sack is free of such treatments.

Transparency & Support 84

WildBird states a general transparency commitment about sourcing and manufacturing and names the fiber sources (eucalyptus, beech) for this sleep sack, but no country of manufacture, supplier, or warranty terms are published for this product.

Fastener & Neck-Opening Safety 84

The sleep sack has a two-way zip and has zero-irritation neck construction, but no zip guard detail or specific neck-opening measurement is given, and one parent review reports legs getting stuck due to fabric stretch rather than a fastener failure.

Hardware & Print Safety 78

This sage green sleep sack has a two-way zip but no snaps, buttons, or printed graphics, and the dye chemistry of the colored fabric itself is not addressed anywhere in the product information.

Customer Stories

Sentiment Summary

Customers consistently describe the sleep sack's fabric as very soft and cozy, often comparing it favorably to other popular sleep sack brands.
Several reviewers mention the sack holds up well through repeated washing and drying without pilling, shrinking, or twisting.
Some customers note their baby sleeps comfortably through the night without overheating while wearing it.
One customer felt the polyester filling was not clearly disclosed on the product page relative to how materials are usually listed.
A reviewer mentions the sack runs long in length, though it did not affect their baby's sleep.

Best sleep sack! Great quality

So soft and cozy! This is my 3rd brand of sleep sack I’ve tried and it’s my favorite so far! The material is so cozy and has such a great feel. Couldn’t be happier!

I can't get over how soft this is! Nice and lightweight too, perfect for layering.
