I also wear the Nomex Flying suit to fly at my club, I fly C150/152, C172, PA28 PA28 Arrow T. & fly in other aircraft.
Some take the piss!! Thats thier look out.
I have my frequencies on my left knee pad, My airfeild information Hobbs & flying times on my Right Knee pad. Landing charts for airfields visiting in the knee pad pockets along with aircraft Check lists.
Also i don't like loose aticles like coins, keys & phones in unzipped pockets which is where the breast pockets come in handy on the flight suits.
I also wear leather flying gloves, i think protection from fire as well as other peoples germs from thier hands is a must. (some people don't wash hands after bog visits & also sneeze & wipe thier germs on the controls)
as some one else has said wear what you want.
