An ultra-lightweight umbrella that weighs only 130g using a light-shielding heat-shielding fabric with a light-shielding rate of 99.99% or more and a UV cut rate of 99.9% or more. It is a three-tier folding umbrella that does not pop. HEATBLOCK has a two-layer structure in which a light-shielding film is bonded to the back of the fabric, and with this structure, Ambel has achieved a light-shielding rate of 99.99% or more (the highest value) and a UV shielding rate of 99.9% or more. As long as the fabric is not torn, the shading effect is semi-permanent. HEATBLOCK pentagon has an umbrella frame structure that can withstand wind speeds of 15 m/s by optimizing the combination of materials and part size.
