Checked baggage? Who needs that headache? When you've got everything you need for a perfect getaway in a super-duper carry-on that also doesn't kill your back, you've achieved pro-traveler status (regardless of what your frequent flyer card says). Weekend warriors know that the secret to pain-free travel (on so many levels) is a big ol' backpack that fits everything from your swimsuit to an extra sweater for a chilly bus ride. So grab all your essentials (we've got those covered too if you're in doubt) and hit the road. Summer's just begun and you have a whole lot of traveling to do.
