Bethany's questions on helmets reminded me of this thread on hi viz helmets. I looked at the Lazer, Giro Xar and the Giro Aeon and was leaning towards the least expensive Giro Xar. But instead, I got the Aeon. Team Estrogen sells the helmet and as it is new it seems to be the same price everywhere. (Support TE!).

This helmet is extremely bright, the pictures do not do it justice. It also is a very light weight, comfortable helmet. I went for the pricier Giro partly because I wanted a helmet that was good in hot weather and this helmet is well vented. I already have my Bern for tooling around in and for colder conditions.

I have noticed biking in Texas that cyclists who wear high visibility products really do stand out. It makes a difference. I also noticed years ago when I road a motorcycle that my spouse's and my blaze orange helmets really stood out from afar and even though this is only my impression, I had the feeling that drivers did not follow me as close when I wore that helmet.
