I would just add that you'll have to make a decision whether to wear a jock or compression shorts underneath your pants or shorts.
Also - the past few years, I found good, beltless black slacks in the JCPenney's sale catalog. You usually have to buy two pair at a time, but the price has been as low as under $20 per pair. And no - I don't own any Penney's stock.
BTW - I like the fox 40s with the rubber mouthguard. I soak them in mouthwash (cinnamon works for me) before games.
Gee - it just dawned on me that I should be writing this in the past tense.
