latex seals are tighter.
i have the o'neill bone drysuit. had a shop send to o'neill to get the seals replaced; replaced neoprene neck seal w/ neoprene, change ankle seals to latex. plus, get leak(s) fixed. o'neill called the shop with the price once they've inspected the drysuit...50 bucks! the cool thing is that the shop (wakesports) isn't charging me extra. i'm paying exactly what o'neill is charging.
