All my boxers used to be that sparkly silk stuff. Man, they make your balls chafe like you wouldn't believe. Prepare to do some serious itching, and then wear holes into them because you itch through them so much. I hate silk boxers now.. sure they feel great and are fun and all.. but don't try to walk around too long in them.. like going to school or work or something. They have no problems with riding right on up your ass.
