Full Coverage Doubler Cover - Size LARGE

Full Coverage Doublers (FCD) —

Wool Blend Booster & Lightweight Cover

Bumby's most versatile wool layer — booster, barrier, night solution, and lightweight cover all in one. Simple by design, powerful in practice.

The Full Coverage Doubler does a lot for a simple piece. Built from a soft heavyweight wool blend — 95% wool, 5% lycra — with clean serged edges, no frills, no hardware. The FCD is designed to work hard across multiple roles without driving up the price. We keep it simple so we can pass the savings on to you.

Whether you're boosting nighttime absorbency, protecting your knit wool from felting, or looking for a breezy lightweight option for the beach, the FCD quietly earns its place in your diapering routine.

Ways to Use It

• Night boost — heavily lanolize and use solo at night for serious overnight protection
• Felting barrier — layer between your diaper and knit wool cover to reduce felting and dampness
• Performance booster — pull on over the diaper, then add a cover for maximum protection
• Lightweight cover — a simple, cost-effective option for light coverage at the beach or around the house
• Potty learning — a gentle, familiar layer as you transition out of diapers
• Rise extender — when your cover still fits but the rise is getting low, the FCD adds that extra layer right where you need it
