I can't answer what's ok with co workers for you. How much discretion do YOU want or need?
Personally, I don't wear diapers that thick at work bc they're too thick under pants for MY comfort level. Northshore Supreme Lites are extremely absorbant and MUCH thinner while easily still being 4+hour diapers. Really, only YOU can figure out what you're comfortable with.
The special though is pretend you don't have a diaper on or just act normal dude. I guess I want some discretion. Oh okay I do like the. Norhshore ligjtts.
