I use just the standard wet suit from local hardware store (tare resistant) that go over ur normal work clothes. If u think ur gonna be to hot just wear somrthing light under it like t shirt and tracksuit bottoms or fleece and heavy bottoms if it really cold. I used to wear this when this when i was building blocks b4 resession and worked ok but if its heavy persistant rain it will eventully start to seep through to ur cloths around neck and sleaves.
