This pad uses a high-loft mesh and a deodorizing (Deodorization) and dehumidifying (Dehumidification) mat to absorb sweat and odors, preventing odor transfer and sweat stains on your backpack. The silica gel DD mat, made with a special manufacturing process, absorbs a lot of sweat and moisture, and also absorbs odors. In addition, the Velcro attached to the mat is a pile-type Velcro, designed not to damage the mesh materials of your precious backpack. The DD pad combines these two features: excellent breathability and elasticity from the high-loft mesh, and sweat and odor absorption from the silica gel DD mat. The top of the pad secures to the backpack straps with adjustable-length buckles. The bottom of the pad secures to the backpack straps with large Velcro strips. This allows for easy fine-tuning and easy use with a wide variety of backpacks. Hand washable. Sold at Tokyu Hands, Amazon, etc. Completely unused.
