The official Contenders gear has a royal blue sash for the boys to collect their achievement pins on.
I ordered one and tried to form it into some sort of belt or something less 'Miss America'ish, but I was unsuccessful. It looked girly to me despite my efforts.
As a group, we have decided to go with a more manly vest that isn't official Contender gear...but will be made official with an official Contenders membership pin and an assorted collection of Contenders achievement pins. We'll be ordering these tan denim vests in January when we make our first group pin order. ($12.99 each)
