I'm assuming you're talking about an upper-end travel team of young men (i.e., relatively expensive stuff in men's sizes), as opposed to a low-end kid's rec. team??
Are you talking about just a typical "uniform package", i.e., 2 jerseys, 1 home, 1 away - 1 pair of socks and shorts (sometimes they throw in a ball with this, too), where the kid supplies the extras....or are you talking about supplying just about everything....uniform package, plus 1 pair extra socks, windsuit, bag, goalie gloves, wrist guards, etc., where the only thing the kid supplies is his jock and cup, shoes, and special undershirt (compression or sweat absorbing)...
