I think Sir James will take a look at the potentially to exploit 53 year old Grandmas paranoid about their grandkids falling and hurting themselves AND who care for 88 year old parent who also is unsteady on her feet
safety clothing can backfire -literally. A lady I know was wearing a type of riding jacket that inflates with compressed air if you fall off. She fell of and the jacket inflated and broke five of her ribs and her shoulder.
Not a bad idea but flawed.If children were on scooters or bikes and tearing down a hill and fell off the last thing you want is melted nylon/plastic in open abrasions once gravel had broken through the wrap and friction took over. That is why motorcyclists wear nylon jackets/overtrousers OVER their leathers.
Mama - just seen your link - those trousers only protect certain areas of the body (knees and hips I think)
My idea would protect the whole of the limbs
