i'll be going jungfrau in coming early august. It is summer, i wonder if we need to prepare winter wear when we go to the top. I initially intended to just wear a thick sweater below my windbreaker, not too sure if this is enough or do i need a down jacket. I have not experience winter before as i come from a tropical country. Thanks much for your replies!
