For parents who need to carry a lot but don’t necessarily need the extra size of a Multitasker Backpack, Medium Nappy Bags are a practical solution. These are some of our biggest-selling designs, with different carrying styles, materials and finishes to choose from while still giving you ample room for nappies, bottles, spare clothes, snacks and your own essentials.

Our popular medium-sized nappy bags

Signature Backpacks for hands-free organisation

The Signature Nappy Backpack is a great choice when you want generous storage while keeping both hands free for the pram, your little one or everything else family life throws your way. With a 20L capacity and eight thoughtfully positioned pockets, it gives nappies, wipes, bottles, clothes and personal belongings dedicated places rather than leaving everything loose in one large compartment.

Two insulated elasticised bottle pockets provide convenient drink storage, while padded adjustable backpack straps make carrying comfortable. It also fits a 16-inch laptop, helping the design transition naturally between parenting, work and travel as your family’s needs change.

Carry Alls for parents who prefer a shoulder bag

Carry Alls offer a roomy alternative for parents who prefer carrying their nappy bag over the shoulder rather than on their back. With around 22L of space, these bags sit within our medium-sized range while providing generous organisation for days when you need to pack plenty for your baby or toddler.

Thoughtfully placed compartments, insulated bottle pockets and secure zip pockets help keep everything in its place. Flexible carrying options also let you wear selected designs over your shoulder, crossbody with the included messenger strap or attached to the pram with stroller straps, making them easy to adapt throughout your day.

Plenty of space without choosing our largest backpack

Everyday Totes for a relaxed, versatile option

The Everyday Tote combines a generous 20L capacity with a relaxed silhouette that works beautifully through the baby years and beyond. Available in soft washed cotton corduroy and classic blue denim, it’s designed for parents who want practical nappy bag organisation in a style that feels like an everyday tote.

Seven internal pockets include two insulated bottle holders, while a secure zip-top closure keeps your belongings safely contained. There’s enough room for everyday baby gear alongside your own essentials, making it a versatile choice whether you’re packing for one child, siblings or simply prefer to have a little extra with you.

Find the right balance of capacity and everyday carry

Signature, Carry Alls and Everyday Tote designs make up our medium size of nappy bag at around 20 litre capacity. They’re particularly well suited to parents who carry a lot of stuff but don’t need the additional capacity of a larger Multitasker Backpack. You still have room for changing, feeding and clothing essentials without carrying a larger bag than your routine requires.

OiOi has been family-owned since 1997, designing practical bags around the realities of getting out with little ones. As some of our biggest-selling styles, these Medium Nappy Bags give you a choice of backpack, shoulder bag and tote silhouettes, making it easier to find the carrying style that suits you while still enjoying generous everyday storage.
