Customer feedback is positive about zipper convenience, warmth, fit, and durability, but size opinions vary. Confirm the child’s fit against the stated 32-inch maximum rather than relying on age alone.

Customer feedback highlights the two-way zipper as convenient for diaper changes, alongside positive impressions of warmth, fit, ease of use, and durability. Those comments are relevant to the listed bottom-opening zipper and cotton knit sack, but warmth is subjective and the product has no stated TOG rating. Size feedback is mixed, so use the stated Medium limit of 32 inches when judging fit.
