Get these. I have 2,000+ miles on them and they are holding up great. Prob. get another 2-3000 miles.
Also gloves. I have found that my fingerless sun gloves are perfect all the way down into the 30s. My hands usually start cold leaving camp and are fine 15 minutes into walking.
I bought what Skurka recommended. 1.4oz.
