1. The beanie and its fluffy bobble.
You may not think much about it but did you know that your favorite beanie actually had a use other than just keeping your head and ears warm when it is cold outside.
Most beanies have a big fluffy bobble on the top of it. This was created by French marines that would be stuck in boats for extended amounts of time. The fluffy bobble was added to soften any blow that they head might take from hitting it on the cabin. Smart invention if you ask me.
