Quick answer
Choose a wool diaper cover for natural breathability and overnight absorbency, or the Flappy Nappies Chappy Nappy fleece cover for a lightweight, crotchless design that works with any Flappy Nappy diaper cover.
Material differences: wool vs fleece
Wool diaper covers are naturally breathable and can hold moisture without feeling wet, making them ideal for heavy wetters or overnight use. They require lanolin treatment to maintain water resistance.
The Flappy Nappies Chappy Nappy is made from cozy anti-pill polyester fleece. It is a crotchless pants that snaps to the waist of any Flappy Nappy diaper cover, allowing you to customize the outer layer without buying a full cover.
Fit and compatibility
Wool covers fit like traditional diaper covers and come in various sizes. They are a one-piece solution that goes over a fitted diaper or prefold.
The Chappy Nappy is pants only—the diaper cover and absorbent pads are sold separately. It snaps onto any Flappy Nappy cover, which means you can mix and match colors and sizes. Note that the elastic goes in the back on all Flappy Nappies items.
