The neck gasket on my dry suit is slightly big. Thought it feels firm around my neck, if I'm doing a lot of twisting I take on a little water. It is a medium gasket. I did try a small but after passing out I thought it might be a little tight (OK, I didn't pass out but probably would have). I don't think I could have cut a small gasket back enough to work but I'm surly not an expert on this.
Again, I know their is a lot of expertise out there, suggestions?
Thanks,
Chuck
