The Best Side Mirror Snow Covers
The cheapest item on this site and the one you appreciate most, because iced mirrors are what you discover at the end of the driveway when going back out is the last thing you want.

Quick picks
The short answer, before the detail. Tap any row to jump to that write-up, or go straight to the listing to check today's price.
Mirror covers are a small purchase with a specific payoff. You clear the windshield, get in, reverse off the driveway, and discover both mirrors are still white - at which point you are getting back out into the cold for a thirty-second job you thought you had finished.
They are also the category where the specification is simplest and most makers still get it wrong.
Fit is the entire product
A mirror cover has one job and one failure mode: it either grips your mirror housing or it blows off in the night. So the only spec that matters is published dimensions, and the only useful question is whether the maker sells more than one size.
Car mirrors and truck mirrors are nothing like each other. A compact sedan mirror housing is roughly a hand span; a tow mirror on a full-size pickup is closer to a dinner plate. A single universal size cannot be snug on both, and snug is the whole point.
Two of the four publish nothing. In a category where fit is the only variable, that is the difference between a considered purchase and a coin flip.
Measure yours first
- Measure the mirror housing at its widest point, left to right.
- Measure top to bottom at the tallest point of the housing.
- Buy a cover slightly larger than both, so the elastic or drawstring closes behind the housing rather than stretching flat across the face.
- If your mirrors have integrated turn-signal repeaters or blind-spot indicators, check the cover does not have to sit over a lens you need visible while parked.
Are they actually worth buying?
Honestly: they are the lowest-value item in this whole category, and they are still worth it if you park outside. The reasoning is about sequence rather than importance. Clearing a mirror is trivial - ten seconds with a glove. The cost is that you discover it after you have already finished, warmed up and sat down.
If you already run a windshield cover that includes mirror pockets, you do not need these at all. Several covers in that roundup include them, and buying both is paying twice.
The combo case
The four-piece set that includes wiper sleeves is worth singling out, because the wiper half addresses a genuinely more consequential problem. A frozen mirror is an inconvenience; a wiper bonded to the glass is what tears the rubber off the blade when you switch it on.
If your windshield cover does not tuck over the wipers, wiper sleeves are a real alternative to lifting the arms overnight - which has its own drawbacks on an exposed driveway. Both options are weighed in stop wipers freezing to the windshield.
Do notstretch an undersized cover over a mirror
A cover pulled taut across the mirror face has no slack left to grip the housing behind, so it is held on by friction alone and comes off in the first gust. Undersized is worse than nothing, because you believed the mirror was covered.
The short version
Buy the size-matched SnowOFF in the class that fits your mirrors, or the four-piece set if your wipers are also exposed. Skip anything that does not publish a dimension, because in this category the dimension is the product.
And check your windshield cover first - if it already has mirror pockets, this is a page you can close.
The picks, one at a time
We haven't tested these
No lab, no borrowed units, no free samples. What we did do: pull every published spec into one table and work out what the numbers mean on a cold morning. Everything below traces to a published spec sheet, a manual, or a standard we can point you at - and if a figure isn't published, we say so instead of estimating it. The full method is here.
1. Best for cars
SnowOFF Car Side Mirror Snow Covers, Set of 2, 10.5 x 9.5 in
Publishes its dimensions, which is the entire purchase decision on a mirror cover. 10.5 by 9.5 in is the car size, and a cover that is too small simply will not stay on overnight.
Best for: Cars and small crossovers
What the maker publishes
- Size
- 10.5 in long x 9.5 in high
- Fits
- Cars, CRV-class crossovers
- Quantity
- Set of 2
- Extras
- Cloth included
- Material
- Not published by the maker
What works
- Published dimensions in a category where almost everything says universal and means nothing
- Two size classes exist in the range, so you can actually buy the right one
- Mirrors are the thing you notice at the end of the driveway, when going back out is most annoying
What doesn't
- No published material, so durability over a season is unknown
- Mirror covers are small and dark and get left on driveways - buy the size that fits snugly
Skip this if: you drive a truck or full-size SUV. The larger version of this exact product exists for a reason.
2. Best for trucks and SUVs
SnowOFF SUV, Truck and RV Side Mirror Snow Covers, Set of 2, 15 x 11.5 in
The 15 by 11.5 in size class. Truck mirrors are far bigger than car mirrors and this is the difference between a cover that stays put and one you find in the road.
Best for: Trucks, full-size SUVs and RVs
What the maker publishes
- Size
- 15 in long x 11.5 in high
- Fits
- SUV, truck, RV mirrors
- Quantity
- Set of 2
- Extras
- Cloth included
- Material
- Not published by the maker
What works
- Correctly sized for tow mirrors and full-size truck mirrors, which most universal covers are not
- Published dimensions again, so you can measure yours first
What doesn't
- Too large for a normal car - it will flap and come off
- No published material
Skip this if: you drive a sedan or compact crossover. Buy the car size of the same product.
3. Best combo with wiper covers
Side Mirror and Windshield Wiper Cover Set, 4 Pieces
Four pieces: two mirrors and two wiper sleeves. The wiper half is the useful part, because a bonded wiper is what actually stops you driving away while a frosted mirror is only annoying.
Best for: Covering the wipers too
What the maker publishes
- Quantity
- 4 pieces - 2 mirror, 2 wiper
- Fits
- Most cars, per the maker
- Protects from
- Ice, snow and frost
- Dimensions
- Not published by the maker
- Material
- Not published by the maker
What works
- Solves two problems in one purchase, and the wiper covers address the more consequential one
- An alternative to lifting wiper arms, which is not ideal on an exposed, windy driveway
What doesn't
- No published dimensions for either the mirror or the wiper sleeves
- Four small items to fit and store rather than two
Skip this if: your windshield cover already tucks over the wipers. Then you are paying twice for the same coverage.
4. Skip this one
BRITENWAY Car Side View Mirror Covers, 2 Pack
A plain two-pack sold as fitting both small cars and SUVs. That flexibility is convenient and it is also the compromise - a cover that fits both is snug on neither.
Best for: A cheap second set
What the maker publishes
- Quantity
- 2 pack
- Fits
- Most cars, vans, SUVs and CRV-class, per the maker
- Protects from
- Ice, snow and frost
- Dimensions
- Not published by the maker
- Material
- Not published by the maker
What works
- Cheap enough to keep a spare set, and mirror covers are genuinely easy to lose
- One size covers a household with two different vehicles
What doesn't
- No published dimensions, which in this category is the specification that matters
- Fits-everything sizing means a looser fit than a size-matched cover, and loose is what blows off
Skip this if: you want a snug fit on a specific vehicle. Buy the size-matched SnowOFF instead.
Questions people actually ask
Are side mirror snow covers worth it?
If you park outside and your windshield cover does not include mirror pockets, yes - they are cheap and they save the specific annoyance of discovering iced mirrors after you have already finished clearing and sat down.
What size side mirror cover do I need?
Measure the housing at its widest and tallest points and buy slightly larger, so the elastic closes behind the housing instead of stretching flat across the face. Car and truck mirrors differ enormously, so buy the matching size class.
Do side mirror covers stay on in wind?
A correctly sized one does, because the closure grips behind the housing. An undersized cover is held on by friction across the mirror face alone and comes off in the first real gust.
Do I need mirror covers if I have a windshield cover?
Not if your windshield cover includes mirror pockets - several do, and buying both means paying twice for the same coverage. Check what yours covers before ordering.
