Bulky winter coats should not sit beneath a car seat harness.
RoSPA's child car seat FAQ does not recommend thick jackets or bodysuits under a harness. The harness cannot be fastened firmly over them, and in a crash it must compress the jacket first, which RoSPA says "reduces the safety of the seat considerably". Keep the harness snug, with only one or two fingers between harness and chest.
In practice that means taking a bulky coat off before buckling up, dressing children in thinner warm layers for the journey, and putting a blanket or the coat over the fastened harness rather than under it. A thin Lightning fleece layer may work, but take it off if it is bulky.
Sizing and layering tips
- Check each brand's size guide. Sizes differ between brands. A size that fits in one range might not fit in another.
- Leave room for a layer. The coat should sit comfortably over a jumper or fleece without pulling at the shoulders.
- Check the sleeves. Your child's arms should still be covered when they reach forwards.
- Layer for changeable days. Several thin layers are easier to adjust than one heavy coat and work better for car journeys.
- Match the coat to your weather. For rain, look for waterproof fabric and taped seams. For dry cold, padding or a puffer makes more sense.
FAQ
What is the warmest type of winter coat for kids?
For cold, dry days an insulated puffer is usually warmest, especially with a windproof outer. Here, the Columbia Pike Lake II takes the warmest puffer spot thanks to its synthetic insulation and Omni-Heat lining.
Should I buy a kids' coat a size up?
Allow enough room for a jumper, but avoid going much too big. Excess space lets cold air in, while oversized sleeves can get in the way. Use the brand's size guide and check the fit over a layer.
What is the difference between waterproof and water-resistant?
Waterproof coats are made to keep rain out, with taped seams preventing water from entering through stitching. Water-resistant coats can cope with light showers, but not sustained rain.
What waterproof rating (mm) does a kids' coat need?
The figure is the hydrostatic head: how much water pressure the fabric resists before leaking. A 10,000 mm rating is well suited to rain. The Regatta Hurdle V is the only coat here with a stated figure, Isotex 10000.
Can a child wear a puffer coat in a car seat?
Not beneath a harness. RoSPA warns that a thick jacket stops the harness being fastened firmly and compresses in a crash. Take the puffer off, use thin layers and lay a blanket over the fastened harness.
