Sounds like you're getting more than a bit carried away there Cam, spare sunglasses lenses? Never understood the need to take a grip cone to a game, if your bat grip's alright when you leave in the morning it'll make it through the game in one piece!
I just take one of everything obvious, plus a spare bat and a few extra bits like spare inners/helmet sweatbands/supports/painkillers/plasters that just live in my kitbag. Will take a spare shirt or gloves if the weather looks very wet or hot, or trainers if going away to a ground with astro nets we can warm up in, but that's about it.
