Our Top Picks
Best Overall: EcoNour Car Windshield Sun Shade
This quality car sun shade from EcoNour blocks the sun’s harmful UV rays, so it will prevent your car from heating up to sauna-like temperatures. You won’t have to blast the air conditioning or worry about burning your hands on hot steering wheels and seatbelts. The sun shade easily pops out, so you can install it on your windshield in seconds. When you’re back in your car, you can simply fold it up and store it in the included pouch, which can fit in your car door pocket or center console. Made from high quality, nylon polyester material, this sun shade is lightweight but extremely durable. It also features a strong wireframe, so it’s sturdy and stays in place. With several different sizes to choose from, you can get one that fits your windshield perfectly, so you don’t have to worry about any sunlight filtering in through the edges. Despite its reasonable price tag, the EcoNour sun shade is built to last and will keep your car cool and protected.
Best for Side Windows: ShadeSox Universal Car Side Window
Sun shades on side windows can protect car seats and seat belts from heating up to dangerously hot temperatures. This ShadeSox side window sun shade provides UV protection, cuts down on sun glare, and prevents back seat passengers from overheating. Easy to install, the ShadeSox is a flexible, stretchy mesh that pulls down over the open car door like a sleeve. Unlike roller shades or stick-on tinting, you can roll down the window and still stay protected from the sun. And you don’t have to worry about your child pulling it down or the shade falling off. Each set comes with two shades as well as a bag for storage.
Best for Rear Windows: Munchkin Brica White Hot Sun Shades
Using a sun shade on your rear window can help prevent the back seat and kids’ car seats from heating up and helps keep backseat passengers cool and comfortable. The Brica White Hot Sun Shade from Munchkin comes in a pack of two rear window shades. The shades come with both adjustable clips or suction cups, so you can choose how you want to hang them on your windows. These retractable shades are made of mesh fabric and feature a button that you can push when you want the shades to be rolled up. The mesh fabric blocks against UV rays but also allows for visibility, which can help against motion sickness. Best of all, these shades include an indicator that will glow when the car gets too hot. Each shade measures 14 x 17 inches.
Best Collapsible: ShineMatix Two-Piece Windshield Sun Shade
Some sun shades can take up a good portion of your trunk when not in use, but the ShineMatix Two-Piece Sun Shade folds up compactly to save storage space. You simply twist and fold the two shades over each other into a small circle, wrap the circle with the elastic straps, and then tuck the shade into its carrying case. Many reviewers noted that it was small enough to fit into back seat pockets or the space between the passenger seat and the car's console. When not folded up, this sun shade consists of two identical rectangles that measure 23.5 x 29 inches. It's made of high-density nylon that protects against 99 percent of UV rays and is available in three different sizes, so you're guaranteed to get one that fits your windshield properly.
Best for Babies: Enovoe Car Window Shade
Although most cling sun shades are made to protect your baby from the sun, the Enovoe Car Window Shade stands out for a number of reasons. In addition to blocking over 97 percent of harmful UV rays, the sun shade boasts a dual-layer design: a mesh side for visibility and heat protection, as well as a static cling back that offers easy window installation and removal — without the use of adhesives. The 21 x 14-inch shade will also fit most side car windows, including SUVs, minivans, large sedans, and other full-sized cars. Keep your baby (and car) cool with the Enovoe shade, which comes in a pack of four.
Best Retractable: Twing Foldable Sun Shade
Retractable sun shades are a great option for cars because you don't need to constantly remove them when not in use. The Twing Foldable Sun Shade uses a pleated design that can be retracted to one side of the windshield whenever you're not using it. It uses suction cups to attach to your window and easily stretches out to cover the entire surface. It's made of four thermal layers that shield UV rays and keeps your car cool. This sun shade can stretch to a maximum length of 63 inches, but it can be trimmed if your windshield is shorter.
Best for Smaller Cars: Magnelex Windshield Sunshade
If you have a smaller car, this Magnelex sun shade is a great option to keep your vehicle cool and protected from sun damage. It’s made of a reflective polyester material that blocks heat and sun. This shade is 59 x 31 inches and users love that it covers the entire windshield, giving you maximum protection from the sun. When you're done, you can easily fold up the car sun shade and store it in the included bag, which can be stashed under the seat or in the trunk. The shade also comes with a steering wheel cover sun shade, which fits over your wheel to prevent it from heating up and fading from sun exposure. If you have a larger car, the Magnelex sun shade also comes in other sizes.
Best Universal Fit: EzyShade Windshield Sun Shade
For sun shades that'll fit most cars (while still providing the best coverage), consider the EzyShade Windshield Sun Shade. It comes in two, identical rectangular shades that'll adapt to your car's windshield, allowing you to install them vertically or horizontally. Along with a better fit, overlapping the two sun shades ensures over 99 percent of UV protection and over 82 percent of heat reduction. Its double shade design also keeps your car cool, while the shades are easy to fold, install, and store away in the pouch.
