Depending on your body type the new goodnite XL may still fit you. I'm 180 and 5'6 and I wear them while working out as they are thinner and I don't need as much protection while I'm working out and sweating.
I'm not sure there is anything comparative to them in adult sizing though. Your best bet for staying that discreet is the shields if that is all you need. Someone else may know of another product, that I don't, that is as thin as the goodnites.
