Magnelex Car Windshield Sunshade

The Magnelex uses two layers of 240T aluminized polyester: a silver reflective outer layer that redirects solar radiation back outside, and a black polyester inner layer that absorbs any remaining heat before it reaches the cabin. Both layers are 240T polyester fabric — there is no foam or bubble-wrap core. The dual-layer construction is confirmed in the product's cross-section image.

The Magnelex uses a twist-fold (pop-up) mechanism enabled by the memory-wire frame around the perimeter. To collapse: fold the shade in half keeping the frames aligned, then grab opposite corners and twist them in opposite directions simultaneously. The shade will spring into a compact disc shape and fit in the included storage bag. Community reviewers note a learning curve of a few weeks before the motion becomes automatic — Magnelex's YouTube tutorial covers the fold step by step.

Magnelex offers Medium (59 × 31 in) for sedans and compact cars, Large (63 × 33.8 in) for most SUVs and minivans, X-Large (65.7 × 36.4 in) for full-size trucks and large SUVs, and a custom-fit variant for the Tesla Model 3/Y. Check the manufacturer size chart (visible in the product listing images) to confirm the correct size for your vehicle.

Community reviewers with 52,964 ratings at 4.3★ consistently report a noticeably cooler interior and steering wheel with the shade deployed. One review (via Yahoo Lifestyle) cited 15–20°F reduction. The manufacturer claims '2X heat blocking' vs. their single-layer design — that claim is an internal comparison and has not been independently verified with thermometer data by the community. Qualitative cooling reports are widespread and consistent.

The listing includes two pieces: the windshield sunshade itself and a bonus steering wheel sun shade. A storage bag is also included for storing the folded windshield shade.
