All-in-One Diaper | Oh Deer - Happy Bear

Bamboo and cotton lining · Polyurethane laminate outer layer · From birth (4 kg) to potty training (15 kg) · Brand: Happy Bear

As simple as a disposable. As sustainable as a conscious choice.

The Happy Bear All-In-One Diaper is the reusable diaper designed for those who want all the benefits of an eco-friendly option without giving up the convenience of a disposable. Thanks to the Velcro fastening and integrated design, it can be put on and removed exactly like a disposable diaper - but it lasts for years, not hours.

The interior in soft, velvety bamboo keeps your baby's skin dry and comfortable, while the double leg leak guards drastically reduce the risk of side leaks - one of the most common problem areas with reusable diapers.

Key features

• All-In-One (AIO) - everything is integrated, with no insert to assemble: ready to use like a disposable diaper
• Double leg leak guards - an additional leak barrier, particularly effective for active babies
• Durable Velcro fastening - quick, secure changes, even with a baby who won't stay still
• Adjustable size with snap buttons - suitable from 4 kg to 15 kg, from birth through potty training
• Bamboo velour interior - exceptionally soft, breathable, gentle on sensitive skin
• Absorbent lining: 55% bamboo, 25% cotton, 20% polyester
• Interior: 80% bamboo, 20% polyester
• Waterproof outer layer: 100% polyurethane laminate - retains moisture without allowing it to escape through the outer layer
• Quick drying time compared with other reusable diapers
• Washable at 40-60°C
• Compatible with extra boosters for heavy wetters or overnight use

⚠️ Fit note

The double leg leak guards make the fit slightly snugger around the thighs than with other AIO diapers. This is an intentional design feature - these guards are what ensure leak protection - but it is useful to know in advance when choosing the right size.

How to increase absorbency

For heavy wetters or overnight use, you can add an extra bamboo or hemp booster (available separately in the Happy Bear range) to increase absorbency without changing the diaper. For bowel movements, use the practical disposable bamboo liners instead: after changing, simply remove and dispose of them.

Use & care tips

• 🧺 Washing: 40-60°C. Fold the Velcro inward before washing to prevent it from catching on other garments.
• ❌ Do not tumble dry - heat damages the elastic and the waterproof polyurethane layer.
• ❌ Do not use fabric softener - it leaves residue on the fabric that reduces absorbency over time.
• 🌦️ Drying: air-dry outdoors, preferably in the sun. Sunlight naturally sanitizes and helps maintain the colors.
• 💧 Break-in: bamboo diapers reach maximum absorbency after approximately 10 washes. Rinse 2-3 times before first use.
