I'm headed on a long trip to very hot climates in a month or so. I'm looking for a blazer that is super lightweight and won't wrinkle much. I'm leaning a little toward the informal (against gold buttons, etc.) I don't love the options below. The orvis is a three button and looks a little warm. Likewise the first LL Bean, which is appropriate "year round." I like the style of the LL bean a little more. Any other ideas? I know of the Belvest Jacket in a Box but can't really find them. I'd also prefer not to spend more than 500-600.
I think I would like this if it were in blue or a nice light grey, http://www.llbean.com/llb/shop/63015?feat=605-GN1
