Per Brian Nystrom:
2. discomfort of neck gasket

Trim it to fit and the problem is solved. It only takes a few minutes.


Maybe I'm the only one, but I find my dry suit neck gaskets more comfortable
than some wet suit necks.

As others advise: trim.

But go slowly when trimming. Take it one ring at a time and wear it between
cuttings.
