Are you looking for lightweight? Breathable? I wear Helly Hanson impertech II raingear and it keeps me dry, but it doesn't breathe. If you hike a ways you will get hot. If you are just sitting around though they work really really well. My only grip with them is there is no material that goes over the cuffs, so if you wear gloves your sleeves channel all the water right down into your gloves.

Whereabouts will you be going?
