Size 2 Cloth Diaper Cover - Off-Leash Waterproof Swim Outer (18-35lbs)

In this review of the Size 2 Esembly Outer in Off-Leash, the bottom line is simple: parents who want a versatile, durable waterproof cover for cloth diapering or swim use will appreciate its fit and sustainability. The reviewer found it particularly useful for active babies between 18 and 35 lbs who need a trim, leak-proof outer layer over absorbent inners or prefolds. The cover's recycled TPU construction and thoughtful snap adjustments make it a practical, long-lasting alternative to single-use plastic pants.

Key Features

• 100% Recycled TPU Fabric: Provides a waterproof yet breathable shell that keeps clothing dry while using post-consumer plastic bottles for sustainability.
• Two-Row Snap Adjustment: Lets you adjust waist and leg openings independently to fit big bellies or narrow thighs for a secure, custom fit.
• Dual Purpose Design: Functions as a diaper cover over absorbent inners or as a standalone swim diaper when used without absorbency.
• Trim-Fitting and Stretchy: The soft, stretchy construction stays close to the body so it works under clothing and resists sagging when wet.
• Safe Materials: OEKO-TEX certified and free of lead, BPA, PVC, and phthalates, reducing exposure for sensitive baby skin.
• Reusable and Cost-Saving: Designed to work in a small rotation of 6 Outers with 20-24 inners, cutting waste and long-term diaper costs.

Who It's For

Parents using cloth systems who want a reliable outer layer for babies roughly 18 to 35 lbs will find this cover very useful, especially those who plan to use separate absorbent inners or prefolds. It also suits families who want a reusable swim diaper that looks and performs like a cover without added absorbency.

Those who primarily use one-piece fitted diapers with integrated waterproofing do not need a separate outer, and parents seeking a completely adjustable one-size-fits-all shell from birth may prefer the Size 1 option for newborns. The Outer is intended to pair with Esembly inners or other prefolds and fitteds rather than replace absorbency.

Pros & Cons

Pros

• Durable recycled TPU resists wear, lasting through frequent washing and swim use.
• Independent waist and leg snaps deliver a secure, leak-resistant fit that reduces blowouts.
• Lightweight and trim enough to wear under clothes while still containing messes.
• Safe, certified materials make it appropriate for sensitive skin.

Cons

• Requires a separate absorbent Inner (sold separately) to function as a full cloth diaper, which is an extra purchase.
• Size 2 covers a wide weight range but will not fit newborns, so multiple sizes are needed as baby grows.
