I've always had big bags. Why?
A) I take too much kit to matches (2 bats, pads, 3x gloves, 2x shoes, box, lid, strippers, 2x trousers, 2x shirts, 2x jumper, many caps, accessories, training kit [eg hoody, shorts, track suit bottoms], wash bag, towel, magazines, gripping cone, sunglasses + large case with spare lenses) - I've probably missed somethings
B) I like to keep my kit organised (I methodically pack my kit EVERY Saturday morning) and I don't like squashing stuff in
C) I keep all my gear packed away at home and a big bag holds it all
