For helmets I'd suggest a Pret Helmet. Best fitting and lightest helmet I've ever worn. Venting is second to none. Exstatic liner, dial in RCS fit system, magnetic buckle under your chin. They are bomber and have a very low profile. High end is the Effect and Effect Carbon. Personally I wear the Shaman, but the Cynic is the best seller and has appeared in Gear of the Year for the last couple of years at that $100 price point.
