Hi Phil, both Abena and Allanda work fine for me. In fact, I would not be able to tell them apart except the waistbands are different colours. I suppose they do look rather flimsy but they are quite strong. There is no front exit. They look like women's maxi briefs without gusset - not needed because of the pad. They can be pulled up past my suprapubic entry point to my navel to cover the whole of the pad, so they cover any arousal without popping out. I have never tried any other brands.
My pads were prescribed by my district nurses. On most days they are not needed but have always been adequate when they have been needed.
