What to Compare Before Buying
- Size: The stated size is 5-6 years, so check the child’s measurements and preferred fit.
- Waterproof performance: The trousers are tested to 3,000 mm, which is the figure to compare against the conditions you expect.
- Breathability: The stated rating is 3,000 g, so compare that with how active the child is likely to be.

Choosing the Correct Version
Make sure you choose the black version in size 5-6 years if that is the fit you need. The same product name may appear in other sizes, so the age band and colour are the details most worth confirming.
Before You Decide
Confirm the size, colour and warmth level before choosing. The waterproof and breathable ratings are clear, but the right fit and lining weight will matter most in everyday use. For a child who needs weather protection for walking or travel, these trousers offer a straightforward option to compare on those points.
