3 season – RailRiders EcoMesh, but I'm going to get a pair of those Bone Flats and try them out. I like the ventilated panels, and I like the Bone Flats ventilation on both sides.
Cool/cold wet weather – Depending on how cold, either GoLite Reeds or RAB Bergens. GoLites are, well, light, and not too hot for cool/cold weather hiking. The Bergens are a bit heavy, but a very nice eVent rain pant. Only skivvies underneath either.
Cold (winter) weather – RAB vapor-rise. Breathe exceedingly well while keeping me warm enough on the move, and dry pretty quickly. Nice to sleep in.
