Head protection is obviously the priority when it comes to helmets, and it continues to be realised by using expanded polystyrene structures shrouded in polycarbonate shells. But new aspects are coming into play as our understanding of the dynamics of crashing deepens.

The newest helmets on the market now incorporate MIPS (multi-directional impact protection system), which provides extra protection against the rotational forces your head encounters during a crash.
The thing is, helmets are now expected to provide more than just protection, which complicates matters somewhat. And the main thing people now look for, aside from protection, in a performance road helmet is an aerodynamic advantage, which naturally has an effect on a lid’s shape, size and overall look.

Any lid that has even the slightest leaning towards competition will have been analysed and experimented with in the wind tunnel to reduce drag as much as possible. But whatever form these aerodynamically optimised helmets eventually take they still need to be comfortable, so padding and sizing options/adjustability are things you should pay close attention to before parting with your cash.
A helmet also needs to keep your head cool when conditions heat up so it needs to be able to do a good job of providing ventilation, too. And as if all that wasn’t enough, helmets are increasingly being used as a place to store sunglasses when they’re not on your face. So if you haven’t got space for your shades in your pockets it’s worth considering whether the helmet you’ve got your eye on has a way of holding on to them.
