Most of you have seen some of the super cool batman helmets for motorcyclists (Inspiration: Batman helmet - Helmet dawg), which look super sharp yet are quite expensive. Moreover for europeans shipping costs for such baby would equal to almost full price of the helmet itself, thus why not to make one on your own?
This instructable will guide you step by step on material needed to produce road worthy and aerodynamic batman helmet from scratch. You don't even need advanced skills, studio or proper workshop to make this one happen.
What you will need (or anything along the lines, I tried to make this on a strict budget in case experiment happens to be fruitless):
Time: around 4-5 hours in total (two weekends)
Prepare the helmet base itself. That includes taking off all the decals, making sure visor is detached to avoid any scratchings etc. In my particular case helmet came with printed on marks and not simple stickers/decals, which left me with only option of sanding it off.
