## Why we chose it

Petite Crown uses a polyester outer with TPU lining: no fluorinated waterproofing, no PFAS pathway. The one-size snap system adjusts from roughly 8 to 35 pounds, making it the most affordable true snap-adjustable option here. CPSIA compliance is listed on the brand site alongside full material composition.
