The ATGATT brigade has a strong following in some parts of the internet.
It's not a bad thing. At 30mph you can do some serious damage. gear does not just provide abrasion resistance, but twist/impact and other protection that can cause life changing injuries.
A serious hand/wrist fracture can be something you live with for the rest of your life.
Everyone should wear ATGATT, if people do not it's their choice. Does not stop me thinking they are foolish though.
With regards to ATGATT, would kevlar jeans and this kevlar hoody in question not be ATGATT?
