Pata makes nice (albeit expensive) stuff. For 3 season use, some of my favorite pieces include the nano puff pullover (the only insulation needed for wet weather down to 30F), the houdini windshirt, and rock guide pants.
For winter, I swap the rock guides for lightweight guide stretch woven pants, and add a down hoodie pullover for additional insulation. I prefer merino myself, but the capilene line of baselayers is probably amongst the most used ever.
If you have just inherited a patagonia windfall, congratulations. Patagucci gets bashed quite a bit, but their stuff is generally well made and durable.
