13 Best Lightweight Cardigans at Amazon Under $30

New York fall weather keeps me on my toes. One minute it’s gray and chilly, and the next the sun breaks through making it feel like summer again. That’s why I lean so heavily on cardigans this time of year—they’re the answer to unpredictable temperatures. I can wear one layered over a T-shirt during a brisk morning commute, slip it off and drape it over my shoulders when the afternoon warms up, and button it up as a top for dinner out. Not many pieces in my wardrobe flex this easily between style and function.

Because I rely on cardigans so heavily, both for my everyday fall fashion looks and when I’m planning travel outfits, I’m always on the hunt for affordable, versatile styles. That’s how I ended up diving into Amazon’s cardigan selection and finding some lightweight gems for less than $30. From cropped knits I can pair with a maxi dress to striped sweaters that make comfortable jeans look more polished, these are the pieces I know I’ll be rotating through all season long, whether I’m at home in New York or packing for a trip. Plus, prices start at just $16.

Best Cardigans Overall

Urban CoCo Cardigan

Chocolate brown feels synonymous with crisp fall days, and this cardigan nails the trend in an easy-to-pack layer. I love it with dark denim and a white tee for casual sightseeing, or with a denim skirt for a slightly more polished dinner look. The monochromatic buttons and cohesive shade pair beautifully with suede ballet flats, giving you that chic, coordinated vibe without trying too hard.

Chest Cropped Cardigan

A cropped cardigan is such a space-saver in your carry-on, and this navy version goes with practically anything. Style it buttoned up with wide-leg trousers for a travel day outfit that looks put-together but comfortable, or toss it over a maxi dress for breezy evenings. The cropped cut and petite buttons give it a modern, flattering fit, making it versatile enough for both city breaks and lake escapes.

Saodimallsu Striped Cardigan

Stripes are a timeless way to make an outfit look elevated without overwhelming your look. This black-and-white knit has a subtle French feel—picture yourself layering it over a black slip dress for a dinner out in Paris, or tossing it over jeans and a tee for a long day of exploring. Whether buttoned or open, it strikes that balance between classic and stylish that works in any destination.

Merokeety Cardigan

A deep wine shade feels festive for fall trips, and this cable-knit cardigan adds instant polish to even the simplest outfit. The gold accent buttons dress it up just enough for dinners on vacation, while the knit makes it cozy enough for a long train ride. Wear it over a turtleneck with jeans for a layered travel day look, or drape it across your shoulders with a midi skirt for a city stroll.

Trendy Queen Cardigan

If you want a piece you’ll wear on repeat, go for a neutral like this classic grey. It’s the kind of cardigan that looks just as good styled casually with baggy jeans and sneakers as it does layered under a trench with heeled boots. For travel, it’s the definition of effortless—a layer that matches everything in your suitcase without taking up much space.

Fuimsul Crop Cardigan Shrug

This cropped shrug is the piece you’ll be glad you packed “just in case.” Its ribbed knit and batwing sleeves give it a lightweight feel that doesn’t overwhelm your outfit, making it great for tossing on over a tank top when the AC is blasting in the airport or train. Because it’s compact, it’s also an easy one to throw in your carry-on for unpredictable weather.

Amazon Essentials Cardigan

Every traveler needs a basic black cardiganand this one—with over 15,000 five-star reviews—is a budget-friendly win. One reviewer even called it the “perfect travel sweater.” Wear it open over a tank and sweatpants for a laid-back flight outfit, or button it up for a cleaner, office-ready look if you’re heading straight to work after your trip. Bonus: it doubles as a chic shoulder-drape when you don’t actually need a layer.

Unclecat Block Cardigan

Olive green feels fresh for fall, and the white-trimmed neckline and sleeves make this sweater stand out from your standard neutrals. It’s the type of sweater you’ll wear to Sunday brunch, but also layer over a tank for a day at the office. The contrast details elevate it, making it a subtle statement piece without veering too bold.

Merokeety Open-Front Cardigan

This open-front cardigan is the definition of cozy versatility. The flower detail adds just enough interest without being loud, and the roomy front pockets are a bonus for keeping earbuds, a wallet, or your boarding pass within reach. It’s the kind of sweater you’ll wear fireside on a cabin getaway and also rely on for errands or city strolls in cooler weather.

Prettygarden Cardigan

This tan cardigan is lightweight enough for transitional weather but still provides just the right amount of warmth for chilly flights. The gold heart-shaped buttons add a sweet, feminine detail that makes it look more expensive than it is. Pair it with trousers for a chic travel day fit or with jeans and loafers for a casual sightseeing afternoon.

Anrabess Cardigan Jacket

Halfway between a cardigan and a jacket, this piece is perfect for early fall when you need a structured layer without heavy outerwear. The textured knit gives depth to your outfit, and it’s easy to dress up with a skirt and boots or down with jeans and sneakers. Think of it as the polished layer you’ll want for walking tours, dinners, and everything in between.

Amazon Essentials Cropped Cardigan

With a V-neckline, ribbed sleeves, and rich espresso brown shade, the Prettygarden cropped cardigan feels far more elevated than its $24 price tag. It’s a suitcase-friendly layer you can throw over a dress for a dinner out or wear buttoned as a top with high-waisted trousers. Because it’s so classic, it’ll stay in rotation year after year, both at home and on trips.

Shenhe Colorful Cardigan

If your fall wardrobe leans neutral, this colorful striped cardigan is the easiest way to add playfulness without sacrificing comfort. The knit is lightweight and breathable, making it just as good for crisp autumn mornings as it is for spring travel later in the year. I’d wear it with straight-leg jeans and sneakers for exploring new cities, or layer it over a slip skirt to make evenings more fun.
