Rivers Rage Crossfit. Logo for a new crossfit gym in Duvall, WA. If you’re like me, you’ve heard of crossfit (it’s all the rage) but haven’t done a crossfit workout. But I bet you haven’t designed a crossfit logo, so I’m one up on you. I created two versions of the logo to allow the client maximum flexibility in promoting their new gym. Flexibility. That’s what you get when you hire the Itchy Dog. And flexibility is good. You should probably stretch before a crossfit workout, too.
