The main body inside and outside is constructed of 840 DTPU (Denier Textured Polyurethane): Denier is a unit of measurement for the linear mass density of fibers. The use of 840 DTPU indicates a high level of durability and resistance to wear and tear. Textured Polyurethane enhances the material’s strength and provides a robust outer layer. This makes the cooler capable of withstanding rough handling and environmental elements.

Bottom and top material - EVA (Ethylene Vinyl Acetate). EVA is known for its flexibility, lightness, and shock absorption properties. We placed EVA at the bottom and top to enhances structural integrity and insulation. The bottom EVA provides a protective layer, making the cooler more resistant to impact when placed on various surfaces. The top EVA can serve as additional insulation and durability.
