Kokotat, Stohlquist, and perhaps others seem to be offering neo gaskets for some of their drysuits.
My take from the ads is that the neo gaskets are more comfortable, but not necessarily 100% watertight.
Anyone have experience with both that someone considering a drysuit purchase would benefit from?
Also... is a relief zipper worth $150?
