Couldn’t find a thread in this topic, so here goes…
I’ve always liked working in overalls, especially those with lots of pockets. Perhaps thinking of Sydney Cotton’s flying suit, I recently climbed into my plane wearing my favourite old overalls and quickly discovered how unsuitable they are. The leg pockets easily caught on bits as I simulated an emergency exit. These pockets are damned strong, so we’re not going to tear our way out of a pranged or burning aeroplane.
In winter I habitually wear a wool jumper rather than a jacket; it is less flamable and easier to tear if it catches on something while climbing out.
Lots of shirt pockets are handy for pens, phone, etc.
