The T-100 was down for a few weeks and I did my 14-mile commuting by mountain bike in 107-degree F heat index weather.
My Bell helmet has no visor nor shading to speak of.Wearing a French Foreign Legion hat underneath fixed the shade issue but cut off the life preserving head ventilation.
My full-GEEK response,was to fashion a 'sombrero' brim out of double-foil-faced rigid insulation board,aluminum duct-taped to the helmet,and an extended 'shade' made from aluminized mylar/foam windshield sunshade fabric,duct-taped to the back of the foamboard.
I looked like the 'Flying-Nun From Outer-Space' but it was amazing how the UV and infrared got blocked and reflected.A real bacon-saver!
In the future,I may attempt a monostrut supported overhead sunshade which loops over from behind the seat,which would self-destruct in a crash.
