Comments about LensCoat LensCoat Lens Cover for the Canon 300mm IS f/2.8 Lens - Black:
So far so good. It fits better than I expected and doesn't interfere with use. Although I initially felt it a little pricey for what you get, it appears reasonably well constructed, makes my grip on the lens a little better, and should help keep my lens looking good(especially when juggling 2 bodies). As the weather gets colder, it may also keep my hands warmer when shooting outdoors.
