volcom, sessions, old oakley, SMS, this years LD is pretty bright green, and yes saga. I'm sure there are more... thoes are just off the top of my head.
check out sagaouterwear.com you'll like them, one of the coolest companies around.
Sorry man, your chances are real low. Saga only sells from their site, and medium sold out first, so everyone who has them probably wants to keep them, because they're so dope. They might make another lime green next year, and someone might eventually sell their pair of this year's. But unless that happens there's no way to get them.
Dammmmit :-(! Any idea when the new saga line will be up on the site? Anyone want to sell their saga moss pants in medium or any other lime green pants in medium, pm me with pics
