Here are the best cashmere sweaters I've tested — my favorite is under $100 and comes in dozens of colors

Naadam cashmere is special because its facilities are powered by a closed-loop system that limits water waste, and their supply chain is operated by workers sponsored by the brand's donations to The Gobi Revival Fund NGO. The end result is a sweater worth investing in.

In addition to pure cashmere, the brand offers the best cashmere sweaters in blended knits like Merino wool cashmere, modal cashmere, recycled cashmere, and other super soft combinations. Their signature is the Original Cashmere Sweater, which has remained under $100 from as far back as 2018, and still maintains its original premium feel. They carry a wide variety of other styles from loungewear to varsity cardigans, in a size range of XXS to XXL.

Quince is one of our absolute favorite direct-to-consumer brands for quality basics at accessible prices. Their original claim to fame is a $50 sweater made from 100% Grade A Mongolian Cashmere. This lightweight crewneck is soft on the skin and can be layered over a collared button down for a preppy look, or otherwise worn as a cozy pajama top. 

Quince's size availability for their best cashmere sweaters ranges from XS-XL. Quince also has maternity sizing and cozy knit accessories to pair with their Mongolian or elevated Super Luxe Baby Cashmere sweaters.

For sound mind on where the best cashmere sweater actually comes from, Gobi Cashmere is a 100% Mongolian company that works with local herders who hand-comb the cashmere fibers, which creates an even softer handfeel. Without third-party interference, Gobi is able to price their signature organic cashmere sweater and hat set as low as $99. They also have pricier options like their silk cashmere blends and heavier knits, in sizes ranging from S to 2XL.

I've worn my Gobi mockneck sweater in lieu of layering up with long-sleeved tees and fleeces, and it's incredibly thick and warm even with just a cami underneath. It's the ultimate solution for anyone who feels encumbered by wearing multiple jackets at a time.

Cashmere Boutique brings the luxury of 100% cashmere to the convenience of Amazon with their array of sweaters and accessories. Be it cashmere slippers, socks, scarves or sweaters – it's all in one place. Their imported cashmere sweaters make a great last minute gift if you're in need of a soft sentiment on a Prime delivery schedule. Some styles range from a one-size-fits-all scale to a standard S-XL.

Reformation offers a range of trend-forward silhouettes, despite the brand's sizing leaving something to be desired. Despite this, the youthful brand puts sustainability at the forefront by offsetting carbon emissions and recycling or donating textile scraps. Their 90/10 Cashmere line offers fashion-forward pieces like cropped sweaters, as well as timeless basics like turtlenecks and cardigans, made from 90% post-industrial recycled cashmere. 

Eileen Fisher's designs are simple, sophisticated, and sustainable from the beginning of their conception to wherever they land in your wardrobe. Their polished women's cashmere sweater collection consists of pure cashmere, cashmere silk blend, or recycled cashmere knits.

The 100% Italian cashmere is a very fine, minimally treated lightweight fabric that feels luxurious to the touch and won't pill over time. The Cashmere Silk Bliss sweaters are knit with silk cashmere blend yarn, and the Lofty Recycled Cashmere is spun using scraps from the cutting room floors of Eileen Fisher's production facilities to prevent waste. Their sizes range from XXS to 3XL.

Everlane is one of our favorite places to buy all kinds of high-quality basics. Their cashmere sweater offerings include subtle updates on traditional styles with a great price tag. Everlane's Grade-A Mongolian cashmere runs from $110 to $230 in sizes XXS to XL. The most popular and versatile style of their top women's cashmere sweaters, The Cashmere Crew, is one of the cheapest and best options, and former senior reporter Mara Leighton calls it the backbone of her fall and winter wardrobe.

Though alpaca wool sweaters are made of a totally different material than the cashmere harvested from the undercoat of goats, they're worth mentioning on this list considering both are naturally regenerative resources. Alpaca wool may also serve as a cozy alternative to those with cashmere allergies. 

Peruvian Connection claims to follow the protocol of "The Technical Norms for Shearing and Handling Alpaca Fiber Fleece" approved by the Peruvian Ministry of Production that enforces ethical treatment of the animals. Their warm, soft sweaters come in your standard solid knit pullovers in sizes XS-XL, with more options in colorful, traditional Peruvian patterns that pay tribute to the origin of the alpaca wool sweater.

Patagonia is a beloved B-corp retail company most people recognize for signature fleeces, but their exemplary sustainability standards also extend to their recycled cashmere collection. Each piece consists of 95% cashmere scraps collected from European garment factories, which is then woven with 5% virgin wool for added strength. 

The four styles of their small but mighty collection of cashmere sweaters (crewneck, turtleneck, and two cardigans) are available in sizes XS-XL.

If you're looking to splurge on a truly unique piece, Leret Leret has whimsical designs woven into expertly constructed investment pieces.The luxury shop specializes exclusively in cashmere and offers a slew of memorable designs while also offering simpler patterns, like stripes or checkers. Each $475-$575 sweater is a limited-edition piece, so be sure to grab your favorite while you can. The unisex sweaters are available in sizes XXS to XXL.

J.Crew is your one-stop shop for the best cashmere sweaters that go beyond your average camel-colored pullovers. Yes, you can take your pick of classic colors at J.Crew's Cashmere Shop, but if it's a bright or unique color you're after, you're still in the right place.

J.Crew is the first US member of the Aid by Trade Foundation, which helps promote sustainable agricultural development — including sustainable cashmere production — and is certified under the AbTF's The Good Cashmere Standard. We also love the brand's inclusive size range, with sweaters sizing up to a 3XL (size 24).

If you're more interested in classic, modest styles of women's cashmere sweaters, Lands' End is the place to expand your selection. Their 2 ply cashmere is on the more expensive side, but the brand hosts sales often. Another pro: Lands' End offers a larger size range than many other cashmere sweater brands on the market. 

The first N.Peal store opened in 1936 at London's original department store, the Burlington Arcade. The brand's luxury reputation was secured when seen on Hollywood icons like Marilyn Monroe and Ava Gardner. Currently, you can shop its "Bond Woman" collection designed in collaboration with the 007 franchise.

Its broader sweater selection has XS-L classic jumpers, turtlenecks, polos in organic 100% Mongolian cashmere with some silhouettes available in reversible and superfine cashmere versions. N.Peal's peak standards for production are fulfilled by their own facilities that harvest, dehair, dye, spin, and knit the best cashmere sweaters that have persisted throughout the label's history.

What is cashmere? 

Cashmere is a thin, soft, and finely textured knit fabric made from the fibers combed from the undercoat of cashmere goats. It gets its name from the Kashmir region of northern India and is distinct from the fibers harvested from sheep that make wool. Even though they're related materials, cashmere is three times more insulating than wool. It's also naturally more breathable.

Why is cashmere so expensive? 

Because of its scarcity, labor-intensive process, production standards, comfort, and long-term durability, a quality cashmere sweater is considered an investment piece.

Expensive cashmere indicates the material's laborious combing and production process. It takes approximately 4-5 fully grown goats to make just one 100% cashmere sweater. Cashmere is also only collected as little as once a year, depending on the area. 

In the US cashmere must also meet certain criteria, including:

• The average diameter of the fiber cannot exceed 19 micrometers. 
• The product cannot contain more than 3% by weight of cashmere fibers with average diameters that exceed 30 micrometers.

As a naturally regenerative resource, 100% cashmere is in many ways more eco-friendly than say, polyester. Still, it does take a toll on the environment, and the available quantity is reliant on the well-being of goat herds, their habitat, and their caretakers. Paying more for a cashmere sweater means investing in the quality of life for those who produce it.
