Helmet - yes, most of the time, great sun/weather protection, especially as I get older. My Snell open face helmets have a problem with wind uplift, don't like a closed helmet in the 3 wheeler, bad visibility. Just ordered a Biltwell roundy looking open face with smoothly faired in visor, should be better, although I prefer Snell construction to the Biltwell polycarbonate plastic. I will let you know how it works out. Hopefully never have to test the plastic like I did with my MGA years ago.
