A windshield shade protects a parked car. A side window shade protects the people in the back seat while the car is moving, which is a different job with different rules: it has to stay put at highway speed, leave the driver able to see, and survive a child pulling on it. The designs split four ways: retractable roller shades that clip or suction to the glass, stretch fabric socks that slip over the whole door frame, magnetic curtains that grab the steel frame above the window, and suction-cup blackout panels. We ranked the side and rear window shades in our automotive catalog by how much glass they cover, how they attach, how much light they block, whether the window still works, and what hundreds to thousands of owners report after a summer of use.
We have not fitted every one of these to a car ourselves; the verdicts rest on the spec sheets and the owner review history. Prices are not printed because they change daily; every button opens the live Amazon page. Folding and umbrella shades for the front glass are a separate subject covered in our windshield sun shades guide, and parents fitting out a back seat may also want our baby car mirrors guide.
How we picked
- Side and rear side windows only. Windshield shades, visor extenders and tint film were left out.
- A stated size, so you can measure your glass before ordering, and a clear description of how the shade attaches.
- Mounting that suits real cars. Suction cups, clips, magnets and slip-over socks each fail on some vehicles, and the fit limits are named for every pick.
- Honest light blocking claims. Mesh shades cut glare and keep visibility; blackout shades block nearly everything and belong on rear windows only.
- Owner feedback from several hundred to many thousands of reviews, with falling suction cups, weak magnets and fit complaints noted.
The picks
Munchkin Brica Sun Safety Car Window Shade with Heat Alert, Helps Block UVA/UVB Rays, 2 Pack, Black
The Munchkin Brica is the shade most parents end up with, and the review history shows why: many thousands of owners and a strong owner rating for a simple roller that does what it says. Each of the two shades is a 15 by 19 inch panel of see-through mesh that pulls down like a blind and rolls back up at the push of a button, so it is out of the way on a cloudy day. You choose the mounting: adjustable clips that hook over the top edge of the glass, or suction cups on the window itself. The mesh softens glare and helps block UVA and UVB while leaving the view out intact, and a patch on the housing turns white when the cabin is too hot, a useful reminder before strapping a child in. The panel is small for the tall glass of an SUV or minivan, the suction cups can let go after a hot and cold cycle, and it will not darken the cabin for a nap. For a rear-seat child in a sedan or crossover, it is the easy first choice.
- Many thousands of owner reviews with a strong owner rating
- Clips over the top of the glass or sticks on with suction cups
- Retracts with one button when the sun moves
- Mesh keeps the view out for the child and the driver
- 15 x 19 inches leaves gaps on large SUV and minivan windows
- Suction cups may need re-pressing after temperature swings
- Mesh cuts glare but is not a blackout shade
Car Window Shades(2 Pack)-Side Window Sun Shades, UV Protection Breathable Spandex Baby Window Covers, Universal Fit Most of Cars, Protect Privacy for Family, Black
A sock shade solves the two complaints that follow every stick-on shade: gaps around the edges and suction cups that drop off. This pair is made from a double layer of high-elastic spandex mesh that stretches over the entire rear door frame like a sleeve, inside and out, and stays there when the door closes on it. The maker rates it at about 97 percent UV protection, and because the fabric covers both faces of the glass you can lower the window for air while the mesh keeps the sun and the insects out, which is why owners also use it for car camping. Thousands of owners give it a strong owner rating. The trade-offs are real: the outside layer gets wet and dirty, the dark mesh cuts the driver’s view through the rear side glass when checking a blind spot, and it does not suit frameless doors or the largest truck doors. For full coverage with a working window, nothing else here matches it.
- Covers the whole window with no gaps at the edges
- Window still opens, and the mesh keeps insects out
- No suction cups or magnets to fall off
- Thousands of owner reviews with a strong owner rating
- Reduces the over-the-shoulder view through the rear side glass
- Outer layer is exposed to rain, dust and car washes
- Will not fit very large doors or frameless windows
Car Window Shades, 2 PCS Magnetic Double Layer Auto Sun Shade for Side Windows Privacy Full Covers/Half Shade Options Back Car Window Curtains for Baby Protection
This two-pack is the most flexible shade here because it is really two shades stitched together: a translucent mesh for ordinary sunny days and an opaque cloth behind it that drops down for a nap or ties up out of the way with the attached ropes. With both layers down the maker claims about 99 percent of light and UV is blocked. It hangs from magnets sewn along the top edge, which grab the steel of the door frame above the glass, so fitting it means opening the door and letting it snap into place. Thousands of owners give it the highest rating among the shades on this page. The catch is the frame: it must be magnetic steel, so test yours with a fridge magnet first, and the 26.7 by 19.7 inch panel is sized for cars and mid-size SUVs. The bottom edge is not fixed, and like every blackout shade it belongs on the rear side windows only when the car is moving.
- Two modes: mesh for the view, both layers for full shade
- Magnets go on and come off in seconds with the door open
- Highest owner rating of the shades on this page
- Thousands of owner reviews
- Needs a steel frame; magnets will not hold on aluminum or plastic trim
- Bottom edge hangs free and can flap with the window open
- Not for front windows while driving
XCBYT Magnetic Car Window Shades for Side Window, 100% Blackout Privacy
The XCBYT set is built for privacy rather than a view. It is a four-piece kit, two triangular shades shaped for front side windows and two rectangular ones for the rear, in black-coated polyester that the maker says blocks about 99 percent of UV and glare. Each front shade carries 12 magnets and each rear shade 14, placed along the top and the sides so the fabric sits flat against the frame instead of hanging like a flag. That makes it the pick for sleeping in the car, changing at the beach, feeding a baby in a parking lot, or keeping a parked cabin dark. Thousands of owners give it a solid owner rating, a step below the top picks, and the low reviews are nearly all from cars whose frames are not magnetic, so do the fridge-magnet test before ordering. The front pieces block the driver’s side view completely and must be removed before you drive. For car camping on a budget, it is the complete set.
- Covers all four side windows in one set
- Front shades are cut to the triangular shape of a front window
- Magnets on the top and sides hold the edges flat
- Thousands of owner reviews with a solid owner rating
- Only works on magnetic steel window frames
- Front pieces must come off before driving
- Heat can weaken the magnets, per the maker
Car Sun Shade Side Window, 2 Pcs Blackout Car Window Shade for Baby Privacy with Storage Net Pockets Auto Curtains 7 Suction Cups for Heat/UV Protection Sun Block Covers
If your door frames are aluminum or covered in plastic trim, magnets are no use, and this suction-cup panel is the blackout alternative. Each shade is a soft 26.7 by 20 inch sheet of three-layer composite fabric that the maker says blocks about 99 percent of sun and UV, held to the glass by seven suction cups rather than the two or four found on cheaper shades. The inside face has three net pockets for tissues, wipes, a pacifier or a handheld fan, a small touch that parents mention often. Hundreds of owners give it a strong owner rating. Suction cups are the weak point of the whole category: clean the glass first, press each cup firmly, and expect to re-seat one now and then in hot weather. The window has to stay closed while the shade is on, and the maker warns it is too big for very small rear windows. It is for rear side windows only when driving.
- Works on any glass, including cars with non-magnetic frames
- Seven suction cups spread the hold across the panel
- Net pockets hold tissues, wipes or a small fan
- Hundreds of owner reviews with a strong owner rating
- Suction cups can release in heat or on dusty glass
- Window cannot be opened with the shade on
- Too large for very small rear windows
PAMASE Set of 3 Car Window Shades, 95% Light Blocking Sunshades
PAMASE sells a different idea: instead of covering individual panes, it curtains off the back of the car. The set has a full-width rear seat divider measuring 67 by 31.5 inches that hangs behind the front seats, two side curtains of 39.4 by 25.6 inches each, and a storage bag. The fabric is rated by the maker to block up to 95 percent of light. The divider joins in the middle with hook and loop so it can be parted, and the curtains slide to one side and tie back when you want the light in. Hundreds of owners give it a strong owner rating, most of them car campers, road-trippers and parents of babies who nap on long drives. It takes more setting up than anything else here and costs more. The divider also blocks the inside mirror, so treat it as a parked or camping feature and check your local rules before driving with it closed. For sleeping in the car, it creates the most enclosed space.
- Divider screens the whole back seat from the front
- Side curtains are larger than most stick-on shades
- Curtains slide open and tie back when not needed
- Hundreds of owner reviews with a strong owner rating
- Takes longer to fit than a magnetic or suction shade
- Divider blocks the rear-view mirror and is for parked use or passengers only
- Costs more than the two-packs

Mesh or blackout?
Mesh shades such as the Munchkin Brica and the spandex sock cut glare and a good share of UV while letting you see through them, which matters for two reasons: a child who can see out is usually a calmer passenger, and the driver still gets some view through the rear side glass. Blackout shades such as the XCBYT, the suction panel and the PAMASE curtains block nearly all the light, which is what you want for a sleeping baby or for privacy when parked, at the cost of the view. The magnetic double layer shade is the compromise, because it carries both fabrics and lets you choose on the day. If you only buy one type, buy mesh for everyday driving and blackout for camping.
Which mounting works on your car?
Suction cups stick to any glass but let go when the glass is dusty or the temperature swings, so clean the window and press each cup hard. Clips, as on the Munchkin, hook over the top edge of the glass and stay put, though the window cannot be fully closed on some thick clips. Magnets are the fastest of all and hold well, but only on steel: many modern doors have aluminum frames or plastic trim, and a fridge magnet held to the frame above the window tells you in two seconds. A sock needs a framed door of ordinary size. Measure the glass before ordering; a shade two inches too wide will not sit flat, and one that is too small leaves a strip of sun exactly where a child’s face is.
Staying safe and legal
Shades are for the rear side windows when the car is moving. Anything opaque on the front side windows blocks the driver’s view of mirrors and traffic, and many states and countries restrict what can be attached to front side glass and the rear window, so check your local rules, particularly for blackout fabric and for dividers that hide the inside mirror. Even on rear windows, a dark sock or curtain reduces what you see in an over-the-shoulder check, so set your door mirrors carefully. A shade is also not a substitute for supervision in heat: it lowers glare and slows the warming of the seat, but it does not make a parked car safe for a child or a pet.
What is the best type of car window shade for a baby?
For everyday driving, a see-through mesh shade such as the Munchkin Brica roller or a slip-over spandex sock, because it cuts glare and UV while keeping the view. For naps, a blackout shade on the rear side window, such as the magnetic double layer shade with both layers down, darkens the seat more.
Can I roll the window down with a sun shade on?
Only with a sock-style shade, which stretches over the whole door frame and stays in place while the glass moves. Suction-cup panels and roller shades are attached to the glass itself, and magnetic curtains hang loose at the bottom, so the window should stay closed with those.
Do magnetic car window shades work on every car?
No. The magnets need a steel door frame above the window. Many newer vehicles use aluminum frames or cover the steel with plastic or rubber trim. Hold a fridge magnet to the frame before ordering; if it does not grip firmly, choose a suction-cup or sock shade.
Are side window sun shades legal while driving?
Rules vary by state and country. Shades on rear side windows are widely allowed where the car has two outside mirrors, while opaque covers on front side windows are generally not permitted when driving. Check local law, and remove front blackout shades before setting off.
How do I stop suction cups falling off the window?
Clean the glass and the cups, warm the cups in your hands or in warm water so they soften, press out the air firmly, and avoid placing them over defroster lines or tint film edges. Re-seat them after a very hot or very cold spell.
