In reply to monsoon:
I have a Squall (original so no stow pocket) and a Squamish.
The Squall gets used a lot, for everything. Cragging, multipitch, winter, alpine, skiing. Great fit, light, breathable, fab hood and very rugged. I take this if I intend wearing a shell. I'm a large in ME
The Squamish is a light windshirt. I wear it for running or have it clipped on my harness when I want an emergency layer but probably won't wear it. I've got it in a medium which is a little trim but the large was massive.
