As a Southern California hiker, I normally rely on a wide-brimmed hat and lightweight long pants and a long-sleeved shirt as my primary defense against sunburn. I prefer to use as little sunblock as possible. One area of concern is the tops of my hands that are routinely exposed while using trekking poles. I've heard of folks using lightweight gloves or even sun shields made of Tyvek or the like, but I apparently didn't pay enough attention at the time to remember much about brands or types.
I'm wondering if anyone here uses some sort of warm weather sun protection for their hands other than sunblock, and if so, what you have learned and what you like. The need would seem to be something that would provide adequate sun protection, yet a degree of ventilation and perhaps even sweat dispersal. They would also need to be durable enough to withstand the rigors of constant trekking pole use without coming apart.
