its tough to find truly waterproof and breathable stuff. if you can, it usually is expensive. I go with a pretty cheap jacket and pants combo made by cloudveilMW. it keeps me dry form the outside, and in the winter it is good for layering and using as outer shell. in warm weather i get wet frm the inside out in them tho.
in the summers I just get a good water proof pack and bring a towel and change of clothes / shoes. thats what seems to work for me so far.
