What about other options?
I live where the summer temps easily break 100. Riding in leathers in these temps will result in heat stroke long before you will need them between you and the road.
To maintain an adequate level of personal protection in the summer I have shifted to Ballist nylon mesh jackets and overpants for those hot summer days. Protection as good as leather and when wet down with a little water they make a good evaporative cooler.
I have read a few reviews of their crash worthyness and I have yet to read a negative comment about good quality equipment.
