Visor Sweat Liner & Sweatband for Hats & Caps - Patented Sweatlock Technology 3 | 6 | 12 | 25 Pack

Are these padded at all? How thick are they? Looking to add a little comfort to hats without bulk. Any insight, please?

Is it for dress hats like pork pies and do they really work?

On a baseball cap fifty nine fifty can you put inside the head liner or does it have to go outside it? Which gives best results.

does the adhesive leave a sticky residue on the inside when removed?
