Outerwear Functions



All PO.P Layer 3 garments are windproof. Keeping out cold wind and air is crucial to keeping kids warm in winter. Tests to force air through the fabrics of our kids coats, waterproofs, baby snowsuits and skiwear are measured in millimetres per second. To be classed as windproof the air must pass through slower than 5mm per second. If a higher value is measured, we do not rate it windproof.


Kids don’t always stay on two feet when playing. Their winter clothes need to stand up to all kinds of play so we stress test the fabrics using a Martindale machine. Our outerwear can withstand over 10,000 rubs on the machine meaning the garment will last not just for one child, but brothers, sisters and friends too. Some of our waterproofs also have extra durable patches at the seat, knees and ankles.


Good outerwear releases moisture from the body whilst retaining waterproofness. Kids' body temperatures can suddenly rise once they begin to play. The heat & moisture created should be wicked away to avoid feeling first too hot & then too cold once the skin cools. Breathability is measured by passing water vapour through fabric & collecting more than 3,000 grams in 24 hours


To test this we attach the fabric to the bottom of a pipe and begin to fill the pipe with water. When the water drips through, we measure the height the water reaches within the pipe!

A garment is said to be waterproof if the pipe can be filled with 3,000mm of water before leaking. We know how tempting a puddle can be, that’s why most of our LAYER 3 products can withstand up to 10,000mm of water! Check each item description for more information.



For a garment to be entirely waterproof, all seams must be "taped" with waterproof material.

This stops the rain and snow from finding it's way through the tiniest of gaps! DWR stands for Durable Water Repellent. This is an invisible impregnation applied to the outer fabric to make the material waterproof.

Quality Childrens Coats jackets


We often receive questions about how warm our coats and jackets are.

It’s a question that is quite impossible to measure in numbers because every child is different and their activity levels vary throughout the day!

We must always bear in mind that every child moves and plays differently and people do not feel the warmth or cold in exactly the same way, so we recommend the layers principle to offer flexibility.



In terms of different levels of heat retention you can look at coats like this:

1st is a coat without padding like our Shell Jacket.
2nd is a jacket with padding and a nylon lining.
3rd is a jacket with padding and a fleece lining.
