Back when Games Workshop released the first plastic Cadians, I wondered why their flak armour did not fully cover their guts. As someone engrossed in history, including historical armour, it always seemed odd. When browsing skis and protective gear in a sports supply store that was shutting down some years ago, it quickly became apparent where that design came from: Chest protective gear from motocross, and in particular protective kit in American football.

Are there other examples of modern sports equipment influencing aesthetic design in science fiction and fantasy? Please share and illustrate with pictures along with text.
