The Innersy Heavy Flow Bamboo variant utilizes a 95% Bamboo viscose and 5% Spandex blend. Bamboo is naturally porous, promoting superior thermal regulation and surface conditioning. The heavy-flow architecture features a 4-layer TPU active barrier that allows for a high water-vapor transmission rate while remaining hydro-impermeable.
The multi-layer gusset extends from the front to the back waistband, providing professional-grade protection for overnight use. The tagless design and smooth seams are intended to reduce mechanical friction on sensitive skin areas.
