What to know before buying

Listing details to confirm

The listing is inconsistent about warmth and materials: the title claims 2.5 Tog and cotton, while the details list 100% Cotton fabric with polyester fill and call it heavyweight. The listing also describes the product as a sleep sack with legs but identifies its blanket form as Swaddle. Confirm the selected version and construction before buying. Its broad season claims do not establish suitability for a particular room temperature.

Who is it for?

A good fit for

Caregivers seeking a legged wearable sleep sack for a baby within the listed 3–6 months and 12–20 lbs range.
Families looking for a side-zip design and a machine-washable garment.

Less suited to
