HI @Sci_Fi_Fan, the betterdrys are an outstanding product in terms of absorbency. Wow 500 ml is very little hydration during the day. I normally drink about 1.5 liters per day. I've seen the i.d product line but never tried them, thanks for sharing your experience with that brand. I trade off discreteness in exchange for a more absorbent product that will handle a ridiculous amount of urine.
