: I used to keep my neck gasket an a short piece of 6" pvc pipe
: between paddles until it was more comfortable. Stretching
: stresses the gasket but one false nick if you trim the gasket
: and you will be heading for the dive shop and a new gasket (and
: they have larger sizes). And BTW they do stress not trimming the
: gasket while stretched.

Do not use PVC for anything. It is one of the most toxic substances ever. Thanks!
