Not sure whether to go for vegan leather, neoprene, or something else entirely? Each OiOi diaper bag material has been carefully selected to suit different lifestyles. Our best-selling option is vegan leather and coming right up in ranking are neoprenes. But every material offers its own unique benefits depending on how and where you'll be using your bag. Here’s a guide to help you choose the one that fits yours best.
Vegan Leather (PU)
Best for: Parents who want a stylish, structured bag that’s easy to wipe clean.
Vegan leather has a polished, premium look that’s perfect for everyday wear or dressing up. It holds its shape beautifully and has a water-resistant finish—making it great for handling everyday spills with a quick wipe.
If your bag gets a little scuffed from regular use, a touch of acrylic polish in a matching shade can help refresh it. We recommend storing it away from high humidity to maintain its quality over time.

Neoprene
Best for: Hands-free lovers who prefer a sporty, low-fuss option that can go straight in the wash. Yes, machine-washable!
Neoprene is breathable and lightweight—ideal for pram walks, daycare drop-offs, or weekend outings. It’s machine washable, so it’s easy to freshen it up when needed.
While it doesn’t have a water-resistant coating like our other materials, you’ll love how easy it is to clean and how comfortable it is to carry.

Nylon (including Sateen, Printed & Quilted)
Best for: Parents who want a lightweight, durable bag with a variety of finishes to suit their style.
Water-resistant, easy to clean, and hold their shape well.
Whether you’re after something classic, playful, or sporty, nylon offers a low-maintenance option that feels effortless to carry.

We recommend neoprene or nylon. They’re breathable, low-maintenance, and easy to clean. If you opt for vegan leather, just make sure to store it in a cool, dry place to avoid humidity-related wear.
