A close fit means better security, comfort and discretion which is why TENA Men Guards have been anatomically designed. The cupping shape allows them to tuck snugly inside the front of most firm-fitting underwear and the adhesive strip on the back sticks to the fabric to ensure it stays in place. They have a Fast Dry Core^TM that locks away fluid and prevents odours from developing. TENA Men Guard Level 1 is just 5mm thin.
