Actually, if you are the principal, then you must have an office. Do like me, I'm a hotel manager, I wear my First Gear mesh jacket and a cycling shirt, MC boots, and jeans, and I keep 4 suits in my office and a pair of Rockports--just change in your office.
The only problem with many mesh jackets, including my FG, is they have generously large front pockets, and for some awful design reason, the pockets are constructed of solid nylon. :jawdrop: The jacket allows great airflow and is a pleasure even in Texas 100 degree/90% humidity, but the area behind the pockets gets really warm in comparison. I'm thinking of having the pockets cut out and replaced with "mesh" pockets...
