Hey, doole. Can't compare re underwear because I wore different with both suits. However, I had a thick padded undersuit on under membrane and leggings and tshirt on under neoprene. If I had worn the undersuit with neoprene I think I would have had heat exhaustion just walking to the shore! Also, it feels a lot less cumbersome with thin gear on underneath. I felt a bit like a Michelin man in the padded one.
