Components of a Helmet
Most helmet liners are made of expanded polystyrene foam. On impact, the liner dissipates the force of the impact to protect your head. Make sure the liner fits your head comfortably and that it's not damaged or dented.
Most cycling helmets are covered with a plastic shell to hold the helmet together in a crash, provide puncture-resistance and allow the helmet to slide on impact (to protect your head and neck). Make sure the shell is intact and in good shape.
Helmet vents enhance wind-flow over your head, keeping you cooler and more comfortable as you ride. In general, the more vents you have, the cooler you'll be.
Find a helmet strap system that's comfortable and easy to get in and out of. Also make sure that it matches your riding style — beefy for rough terrain and mountain trails, lighter and cooler for road racing. Try a couple of different systems before you decide on one.
