    Far better quality than cheap pop-shades I’ve had this over a year and it’s still great

    Engineered to Deflect Heat, Not Just Shade It

    Unlike cheap mesh blockers, ThermoGuard uses a triple-tech layering system a nano-reflective outer film to deflect 99% of UV and solar rays, a heat-insulating aluminum core to absorb infrared buildup, and a soft thermal liner to block interior transfer.


    Drops Interior Heat upto 25°F Instantly

    Without protection, sun-exposed cars reach 130°F+ in minutes. Flintive ThermoGuard reflects solar radiation and seals windshield exposure, keeping your interior up to 25°F cooler

    Opens Like an Umbrella, Folds in Seconds

    ThermoGuard opens instantly like an umbrella, snapping into place without adjustment. Folds down compact and slides into your glove box



    Flintive ThermoGuard is built for everyday drivers who don’t have time to deal with clunky sunshades.

    Bought this as a Father’s Day gift for the hubby. He loves it. It’s so much easier and convenient than the round disk sun shields that you sometimes struggle to put back in the sleeve. Collapses and expands easily just like an umbrella. It fit the hubby’s 2023 Model 3 Tesla perfectly. Highly recommend. I need to check if they have one for my 2019 Mustang. 🤞🏼

    I love this sun shade for my Mazda Cx-5. Living in Florida, this is way more effective than the aluminum accordion styles, and it takes up significantly less room when stowed. Told my husband to buy one too! Highly recommend.

    I took it camping as soon as I got it. I felt that its material was almost exactly the same as my camping umbrella. As a Texas guy, I've been researching sun protection gear for a long time, and this is by far the best car sunshade I've ever used. The weather is not very hot yet, but I can still feel that the temperature inside the car has dropped significantly. Touching it carefully, you can find that its thickness and texture are completely different from other silver-coated SunShade. It is silkier and stronger. The silicone-like texture should be the vinyl material as ad. perfect product

    This sunshade is easy to deploy and when deployed it reduces the interior heat. The sunshade fits perfectly in the window protecting your belongings from damaging sun rays. With it covering the windshield it keeps your belongings hidden from prying eyes.

    Exactly what I was looking for since I live in Florida and it is very hot, I was looking for something like this until I found this car sunshade, it is very easy to use and install and remove I bought it for my 04 Toyota corolla and it looks great, as far as its I have no idea how long it will last since it arrived and I still don't know how long it lasts and how resistant it is. I will update the comment in the coming months. Excellent product.

    I've been pleasantly surprised by this sun guard's performance and design. Initially skeptical due to past experiences with other brands—where the guards were cumbersome and short-lived—this one has proven its worth. It's incredibly flexible, adapting effortlessly to both my Mercedes-Benz and the spacious windshield of our family SUV. The user-friendly nature, reminiscent of an umbrella, makes it a breeze to handle daily. Not only is it sturdy enough to withstand frequent use, but its compact foldability is a real space-saver, allowing for easy storage without compromising any cabin space. With the scorching heat here, using it has significantly reduced the interior temperature of our cars. Truly, it's like having a little slice of shade at our fingertips. A big shout-out to the design team for this ingenious creation

    I love this unique car windshield design. Blocks most if not all sunlight. Quality materials and a well made carrying case. It is very compact and fits perfectly on the door frame. I also noticed a big difference in cabin temperature with this product compared to other products I've used over the years. I've actually ordered 2 of these, one for my wife's car and one for my truck.

    I purchased this sunshade because the inside of my car was 112 just sitting in the driveway while visiting family. My seats and steering wheel were too hot to touch. While searching for a window sunshade, I like the easy way this one opened like an umbrella and covered the window and stored like an umbrella when not in use. It arrived quickly and I used it the first time while in church on a Sunday morning. I was surprised to return to a shaded cool seat and steering wheel and didn’t need to wait for the air conditioning to cool the car down before driving off. My sister was with me both times when the inside was too hot to sit on the leather seat until the car cooled down and the day I first used the sunshade. She was so impressed she ordered one for her daughter’s Toyota minivan. The temperature has been 94 / 97 during both events. So this sunshade certainly made a difference in my car. I love it. I highly recommend it.
