If you don’t want to choose between the advanced protection of full face helmets and the ease of an open face helmet, you can always choose modular or flip-up helmets. These helmets allow the functionality of both of these kinds of helmets, without having to purchase two different helmets or carry two different helmets around. Whether you’re a fan of open face or full face helmets or are just not yet sure which style you prefer, modular helmets are a great alternative, especially for those that are just starting to ride and don’t yet know which helmet will cater to their needs. How do flip up helmets work? The most popular designs have a modular lower piece that can be slid down to create a full face helmet, or slid up to create an open face helmet. When the lower piece is slid up, there is a smaller visor in place to help keep wind and dirt out of your eyes while riding. These types of helmets are perfect for the rider that doesn’t want to have to take off his helmet if he needs a drink of water or wants to talk to his passenger or fellow riders.
