As it's starting to warm up here in the Arizona desert, I'm investigating helmets with better ventilation than my basic entry level helmet. Last summer, when I started cycling more seriously, I discovered that I overheat easily, and in addition to improving my hydration & electrolytes, I want to try to keep my head cooler. Plus my current helmet is a few years old and probably due for replacement anyway.

I've tried on a few brands, and the Bells seem to fit my head pretty well. I was looking at the Array and the Sweep. The Array is a simpler with a rounder shape in the back and costs $40 less. The Sweep seems to have better vents and channels and comes with a shade visor...although I'm not so keen on the pointy back unless it's really functional. It's a little lighter in weight, which is a consideration mainly if it affects keeping my head cool.

Any thoughts?
