Weighs nothing, soft bill, no top button, ventilated all around head. Would seem ideal for under-helmet use per this thread, but I don't like the way my

For one thing, I only get an extra inch or so of bill beyond the helmet's visor. Probably somewhat helpful in low sun, but not enough for me to take the safety risk.
