Pete, like you, I burn very easily. From shorts up, it's wide-brimmed hat & RR L/s shirt. But I too hate long pants and avoid whenever possible
For the last couple years I have had success using Banana Boat skin & scalp spray-on (pump) and have not gotten my legs burned at all. Saw it in the store a couple days ago, so it's still avail.
This is the only pump spray I've found. Pump is important to me because it's easy to repackage into a smaller pump-spray bottle for only a few days' use.
Be sure to spread out the droplets as soon as you spray on though! One time I didn't and got a "polka dot" sun burn!
Finally, it's been a while, but as I recall, Consumer Reports has found combo sunsrceen/repellant to be less effective than each separately (especially the repellant part).
