Helmets are a personal choice. I want get into that. But if you want a nice one, here are some links. http://www.gratefulheads.com; http://www.rockhedz.com; http://www.shredready.com; http://www.happy-2b.com. All are US companies except for happy2b which is European. I have see, owned, or have friends/acquaintenances that have all these (except happy) and they are light, comfy, and will protect the noggin!
