I've commuted for the first ten years with Frank Thomas kit (with soft armor) did find my Jacket got scrunched up quite bad so tended to leave it at work. Just 'upgraded' to Hein Gerick kit with hard armor, with vents. I did try (when slimmer) wearing leathers, but it's such a pain padding to and from the toilets. Far prefer stripping at my desk.
Though one day, I was in my leathers, and walked in the back door. Got collared on the stair case with an urgent cry for help.. so took off my jacket and sat at the bloke's computer, starting to work on the problem. Hazel in customer services kept glancing across at me with a quizzical expression that seemed a bit odd. Eventually, having switched the computer on and off twice I declared it fixed and stepped away from the desk, at which point Hazel cried out and pointed at my Leather's "THAT's why you've been creaking!" she exclaimed.
A few years later, riding across to Huddersfield in the depths of winter, I puff my way up 3 flights of stairs in my Frank Thomas cordura goretex gear, and start to peel away the layers of neck warmers, jacket, trousers etc. A Lass steps up to me and asks me if I'm a skiier. To which, I reply, "Yes, you too?" "no, I just saw you come in in your ski gear and thought you were using that because it was so cold". I held up my Helmet, and looked her straight in the eye (still defrosting so not quite running at full speed) "erm, I was wearing this too", I hopefully point out, thinking she'd get it. She looked at me blankly for a moment before a Brenda from Repairs (who was a biker) put the lass out of her misery.
