Muddy Puddles Kids Size Guide with measurements for height, chest, waist, and leg.

Sizing tip: We often use European sizing along with US sizing to help guide you to the right fit. In many cases, if you know your child's height, this actually can help guide you better than age. We did the work for you so you do not have to convert- use this chart to find their height. Outerwear is made to layer over clothes- getting this right should be all the work you need to do. When looking at boots, use current tennis shoe sizing. Boot sizes are in T (Toddler) and Y (Youth)- not by age.

Frequently Asked Questions

Is this just for rain, or can my child wear it in mud and dirt too?

This is built for more than just rain. It’s designed to handle mud, wet grass, and messy outdoor play all in one piece. Kids can sit, crawl, and explore without soaking through or ruining their clothes underneath.

Will my child overheat in this?

No - this is a breathable waterproof, not a heavy rain suit. It’s designed to keep water out while still allowing heat to escape, so kids can run, climb, and play without getting sweaty.

Is this good for everyday outdoor school use?

Yes - this is exactly what it’s made for. This style is widely used in UK Forest Schools and nurseries because it holds up to daily outdoor play in changing weather

Can it handle light rain or just heavy storms?

It’s perfect for light rain and damp conditions, but also strong enough to handle steady rain when needed. It’s designed as an all-day, all-weather layer for kids who are outside regardless of conditions.

What do kids wear under it?

It’s unlined on purpose, so you can layer underneath based on the weather. Mild weather → regular clothes Cooler days → add fleece or base layers This makes it a flexible, year-round option.

Is it easy for kids to move in?

Yes. It’s lightweight and designed for movement, not stiffness. Kids can run, climb, and sit comfortably without feeling restricted.

Will it actually keep clothes clean?

Yes—that’s one of the biggest reasons parents buy it. It creates a full barrier against mud, puddles, and wet surfaces, so whatever they’re wearing underneath stays clean and dry.
