If you are at the stage of taking your gear into the cockpit with you how about a bag? Not necessarily a specific aviation one but one you could just use for that during your ppl without packing/unpacking each time you fly. I found a small holdall with easy access was perfect during mine.
If someone wants to buy you a gift how about your own foggles, it is nicer than borrowing someone else's if you have a choice.
And of course if you haven't already and someone is feeling really affluent your own headphones?
