More About MegaMax (USA) Tabbed Briefs

MegaMax is specifically designed for heavy incontinence. MegaMax tab-style briefs are up to 3x more absorbent than store brands and features extra tall leak guards at the legs to prevent leaks at the most vulnerable place. The plastic backing keeps the diaper secure after multiple wettings. 

MegaMax USA is designed to offer the same all day or all night leak protection customers love now made stateside. Currently version 2 of this product comes in limited sizes (medium and large) and classic white. We hope to add more colors and sizes in the fall of 2025. 
 

MegaMax uses super sticky tape tabs to keep the diaper secure and snug even after 3 wettings. Many customers will choose to tighten the tape tabs throughout the day as the diaper fills up. The plastic frontal landing zone allows the tapes to stick and restick without ripping. 
 

To activate the brief, fold it lengthways with the backsheet turned outwards and pull the leak guards up in a standing position. You should also squeeze the diaper a few times. This helps to ensure the brief works properly after its been compressed in the airtight packaging.
