As a fair-skinned redhead, it is more than a little confusing to figure out what sunblock or sunscreen to use for mid-late summer climbs. As my other post indicated, we are doing a summer climb on the South Sister and I consider the sun, dehydration, and blisters to be the biggest challenges for my party.
I was planning on applying a good 50 spf chemical sunscreen before leaving the trailhead and then applying zinc oxide as an outer protective layer to my ears, nose, and parts of my face once the sun is higher in the sky. In the past, I've used zinc oxide by itself, but thought I would try something different. However, I'm really not sure what is best. Any suggestions or experiences that anyone could share to shed some [sun] light on this subject?
