Being that I have no choice but to wear diapers under my clothes no matter what I was wearing, that being said I dont believe its the problem the majority would have you believe it is. Personally I have never had anyone notice my diaper in the last 10 years I have been 24/7 but I do tend to wear thinner diapers and I always wear underwear of some sort over them and in warm weather usually lean toward cloth backed diapers but have done plastic backed as well with little issue. I think you may want to rethink the tena stretch super because all american tena products tend to have extra padding in the back of the diaper which may show a little but then given the nature of scrubs being a bit on the baggy side it might not show at all. personally I use tena slip original, seni classic plus, depend, or tranquility ATN for work and the hardest part for me is changing because our shop has 28 mechanics with one stall in the only bathroom on the entire terminal. So long story short pick a thin diaper and wear underwear over it and you will be fine!
