Montane Featherlite or GoLite Whim, the Montane being my choice. There is a price to be paid-- a windshirt can be snagged or ripped, but pants really take a beating, with more mud, dirt, brush, rocks, roots, and abrasion from your own boots to destroy them, not to mention sitting down.
A windshirt protects your core. Pants certainly help and wind pants can keep bugs and sun off too (why are they all black???). But... I would rather wear zip-offs for my "bottoms" wardrobe, or rely on my rain gear for long pants if the weather gets stinky. In my neck of the woods, if it is cold, it is usually wet, so the rain pants will be worn anyway.
