I don't have any trouble with the full suit when needing to go potty. If anything, it's easier than compressive shorts with a waistband, because the shorts don't roll down around the waistband and become a pain to pull back up.

I also partly bought the full suit because it saves me money over decent separates. It also eliminates the "waistband-is-making-me-nauseous" factor, which has been an issue for me since I was a teenager doing equestrian events.

I felt dumb last night, though. I realized that had I gotten the black/turqoise pro suit, it would match my bike!! Maybe next year...
