What to know before buying

Listing details to confirm

The listing details are inconsistent: the title calls the fabric micro-fleece, while the fabric field says 95% cotton and 5% elastane and another field lists cotton. Closure details vary between snap buttons and a two-way zipper. Confirm the actual fabric and closure for the selected listing. The size chart associates 0–3 months with 7–13 lb and height up to 24.4 inches. The stated 1.0 TOG room guidance is 69–72°F.

Customer feedback highlights the material, with a mention of fleece-lined fabric that keeps babies warm, and describes the appearance as cute. This is relevant to a sleep sack sold in a sage checker pattern, but warmth and fabric impressions do not resolve the listing’s conflicting material descriptions. Aggregate ratings skew positive while still including lower ratings, and do not explain the reasons for them.
