It must be horrible to walk around with a Wet puffy!. ...Like Remi Warren says.."must keep the puffy dry at all cost"
Like the rest said, I would get a Merino wool top and bottom layer, a waterproof jacket you can remove after it rains and maybe a cheap pair of rain pants...Remove your pants before you wear the rain pants if it is not to cold. When the rain stops put your pants back on...that way you keep the pants dry.
Look into the grain of the Merino Layer..they come in different thicknesses.
