Hi Anne,
Thanks, I'll look around and see if I can find those sunscreens. I use a zinc oxide one but it has a couple of other ingredients in it to. I may be alergic to the base or one of the other active ingredients.

It turns out that the shorts I wore over my bike shorts are made of a material that makes wearing them like wearing a plastic bag. The outer shorts were retaining all the heat and moisture.

It really is easier just wearing the bike shorts and using the sunscreen. The bike shorts are great at wicking moisture. There is a health food place close to work, I think I'll head over there during lunch.
