My DS's school requires a uniform...basically khakis and polos. DS plays hard. So much so that he went through many pairs of khakis last year because he ripped the knees. Every. single. time. Can anyone recommend a reasonably priced, durable brand of khakis? I heard the Land's End khakis are the best but they are also like $30 a pair...hard to justify that expense when he is growing so fast as well (he grew two sizes over the last school year).
