Doublelayer Technology Fabric Outer layer: 240T holographic coating reflects 99% of UV rays to protect the interior. Inner layer: titanium silver refractive coating blocks heat conduction, helping reduce interior temperature by 3050 F. Benefits: helps prevent instrument panel fading and seat cracking, prolonging the life of the interior. Allweather protection: suitable for summer sun exposure as well as spring and fall UV direct radiation; meets both sunshade and heat insulation needs. Memory Steel Ring Design Fast setup: installed in 3 seconds; unfolds and pops out to set the shape. Stable fit: uses the rearview mirror as a support point; Vshaped cut matches the windshield curvature. No clips or suction cups needed: can be fixed by lowering the roof visor. Durable construction: 1.5 mm elastic memory steel ring can be twisted and folded arbitrarily and stores compactly in the storage bag without occupying trunk space. Universal Fit for Most Models Size: 55.1 inches wide by 27.5 inches . Compatibility: fits compact sedans, twobox cars and most midsize cars. Fitment guidance: measure the width of the original glass before . Flexible orientation: can be placed horizontally or vertically; adjust the curvature of the steel ring to conform to curved windshield surfaces and ensure no light leakage gaps. No Deformation with Repeated Use Lightweight and easy to handle; no burden to carry. Durable frame: metal frame folds without deformation; reinforced stitching around the edges prevents unraveling. Long service life: designed to last about three times longer than ordinary sunshades. Easy maintenance: polyester fiber fabric surface can be wiped clean; it resists water penetration in light rain and maintains reflective performance over time. Practical Use Scenarios Daily summer protection: place the sunshade on the windshield in hot weather to reduce interior heat and protect the dash and seats from UV damage. Long road trips: use during direct sun exposure to keep the cabin cooler and preserve interior materials during extended drives. Seasonal UV protection: deploy in spring and fall when UV exposure is direct to shield the instrument panel and interior from sunrelated wear.
