I keep going back to one dry fit long sleeve, it doesn't have a brand on the tag but its a saltwater soul dry fit shirt...It's considerably cooler than my columbia long sleeve dry fit and probably cost half the price. As for the buffs, I had a couple and I wear them from time to time mainly in winter, I find they make my sunglasses fog up when properly worn.
