Perfect for me

“ These are perfect for me, i get urge incontinence and can't always hold all the way to the toilet, the protective layer goes all the way up the back s if I'm leaking as I get my pants off its still being caught. Life changes really, no I just need more.”

~  Tracy. D  ~

This Style is the best!

"This style is the best, really soft breathable fabric, light to wear and quick to dry, I only use them for light leaks and they worked well. Also like that they sit up a bit higher giving good protection"

~  Helen. P  ~

Honestly the best
