For temps ranging between 20 and 60F, which is what I think you are asking about, I wear pair of polyester stretch sport pants (predecessor to soft shells), a poly 1/2 zip t-neck, heavy wool socks, and GTX trail runners. I take capiline mid weight top and bottoms, a wool hat and fleece gloves. Depending on the anticipated temps, I will add either a windpro fleece jacket and/or a climb high down sweater, and I always have rain gear I can layer on top.
