I love biking! I love Citi Bike! In fact, I love it so much that I plan on biking from show to show during NYFW. One thing I don't love about biking, however, is carrying around a helmet in between rides. See, most helmets don't really fit into most bags, even bigger ones. Most bags are either too narrow or too shallow: the ideal helmet-carrier is both wide and deep so that you can just throw that sucker in there without having to take all this time making it fit. The bag should be easy to secure onto a bike, too. Here are five that I love because they do all of these things very well. And also because they're pretty.
