7 Best Kids’ Waterproof Clothing Brands to Know in 2025

Children thrive outdoors, whether it’s in the playground, at forest school, or on a windswept beach during a family holiday. Across the UK, outdoor play is part of everyday life, and with it comes the inevitable: mud, puddles, rain, and the occasional surprise hailstorm.

That’s why reliable waterproof clothing is an absolute essential for parents. But these days, it’s not just about staying dry. Families are increasingly looking for outerwear that combines performance with sustainability, and design with durability. 

Still, finding the right brand can be surprisingly tricky. That’s why we’ve curated a list of the very best children’s waterproof clothing labels for 2025, starting with a British brand that gets the balance exactly right.

Muddy Puddles – Best for Waterproof Gear With a Sustainability Focus

When it comes to preparing children for wet and windy adventures, few brands understand the British climate better than Muddy Puddles. Founded over two decades ago, this award-winning label has built its reputation on creating waterproof clothing that’s specifically designed to support real outdoor play. It’s tough, it’s functional, and it still maintains the brand’s commitment to sustainability.

A certified B Corp, Muddy Puddles makes its waterproof kits using recycled fabrics since 2017, free from harmful chemicals. How waterproof are the brand’s clothes? Many designs come with a 10,000mm waterproof rating, which is more than enough to handle a downpour on a Dartmoor hike or a week of muddy school runs. Breathability, taped seams, and storm flaps are standard across much of the range.

What makes the brand especially appealing is its attention to how kids move. Every design detail is designed to empower children to explore independently and comfortably.

Kidunk – Best for Toddlers Loving Puddle Play

Kidunk is the kind of brand that knows exactly what nursery-aged children need. Designed in the UK and used in early years settings across the country, their waterproofs are made for climbing, crawling, painting, puddle-stomping, and much more.

Kidunk designs lightweight separates that zip together into full coverage suits. That flexibility makes them ideal for changeable weather and active kids. The range includes trousers and jackets. They are committed to creating a sustainable collection by using recycled fabrics that are easy to wipe clean.

The brand’s offering is focused on younger age groups. But the quality and performance for this age range make it a must-have for toddlers. 

Töastie Kids – Best for Curated Style With Eco Credentials

Töastie Kids is a British brand built around the belief that outdoor clothing should be gentle on children and the planet. Founded by two mums, it focuses on creating waterproof outerwear that’s both practical and beautiful.

Töastie is also a Certified B Corporation, which is a testimony to its sustainability values and strategy. They used recycled plastic bottles to make their waterproof coats, on average, 15 bottles per item. 

It’s worth noting that, while being designed with sustainability as a focus, the waterproof kits are just as kind to sensitive skin as they are to the environment. Töastie’s rainwear range is lightweight and easy to move in.

While the brand’s range is more curated than others, it’s a favourite among parents who value conscious design and contemporary styling.

Patagonia – Best for Sustainable Outerwear With Technical Credibility

Patagonia is one of the most respected names in outdoor clothing for adults. Did you know they have a kids’ range too? The range is limited but it is designed with waterproof and weatherproof needs in mind. Patagonia waterproof jackets are ideal for children who spend a lot of time outdoors.

Sustainability is part of the brand’s history. The brand is also Fair Trade Certified, meaning ethical manufacturing is built into every garment. For eco-conscious families, Patagonia’s commitment to repairs, circular design, and environmental activism is hard to beat.

Additionally, Patagonia’s H2No Performance Standard waterproofing offers high rain protection without compromising on performance and breathability. 

The Bonnie Mob – Best for Design-Led Outerwear

The Bonnie Mob takes a playful, planet-friendly approach to children’s fashion. While best known for its knitwear, the label also sells outerwear. They have a small but charming collection of water-resistant pieces made for babies and young children.

The brand’s ethos is simple: buy once, buy well, and pass it on, since 2005. That means fabrics that are durable, gentle on the planet, and gentle on the sensible skin of young children. 

The designs lean toward the whimsical prints and cheerful colours.

It’s worth noting that The Bonnie Mob focuses on water resistance rather than full waterproofing, but for dry-ish days or everyday layering, it’s a beautifully made, ethical option for younger children.

Polarn O. Pyret – Best for Timeless Scandinavian Durability

Polarn O. Pyret is a Swedish brand with a strong UK following. The brand specialises in long-lasting children’s clothing with waterproof outerwear that is among the most practical on the market.

Designed to handle Nordic winters, it has no issue handling British weather. The brand’s jackets and trousers are built from durable, high-spec materials, with high waterproof ratings. They also have a lot of practical details, including adjustable cuffs and reinforced seams. 

The designs are clean, gender-neutral, and classic, which won’t be for everyone but is a great choice for families that want to pass waterproof gear along. 

Frugi – Best for Bright Rainwear

Frugi is a Cornish brand known for its colourful prints for kids’ clothing. While not exclusively focused on outerwear, the brand has waterproof and water-resistant coats.

Made using recycled polyester and free from harsh chemicals, Frugi’s rainwear is designed to keep playful kids dry. The outerwear is particularly popular for school runs, wet walks, and everyday layering.

That said, Frugi’s waterproof options tend to lean more toward splashproof than full storm-ready, so they may not suit every adventure. But for families looking for personality-packed rainwear that’s as kind to the planet, Frugi ticks all the right boxes.

Waterproof clothing doesn’t need to be dull, disposable, or designed as an afterthought. As these 7 standout brands prove, it can be thoughtfully made, planet-friendly, and tailored to the way children actually play. Whether you prioritise long-term durability, ethical production, or just want outerwear they’ll be happy to wear, there’s something here to suit your values.
