The Gore chamois is just too big for me. I get irritation in the crease and for long rides, bunching and gathering where it doesn't belong. It's really too bad because I love both the fabric/finish of the chamois and the thickness/density. They just cover too much area! In this case, more is definitely not better. For reference, I have an old pair of the Oxygen and I have the Xenon bib and the Xenon short. They all have the same problem.

For reference: I don't know about the Sheebest short/chamois, but I also have a new pair of the LG Neo Power short and I like that chamois a lot. My favorite chamois for longer rides is the Queen from Canari.
