10 Best Fleece-Lined Leggings to Stay Cozy All Winter

The ColdGear Authentic leggings from Under Armour were a top performer in our Lab testing and a favorite among our testers for keeping them extra warm when exercising outdoors (not recommended for extreme temepratures). These leggings feature a brushed interior for a super-soft feel with welded seams that help prevent chafing. The dual layer fabric is designed to help wick away moisture and dry quickly when building up a sweat. Because this pick doesn't have bulky zippered pockets and uses thinner material, it's a great pair to wear when exercising and layer under clothes for added warmth.

With over 23,000 Amazon reviews, these best-selling leggings are available in an impressive 20 colors. They're made with polyester and spandex and feature a large side pocket perfect for your cell phone. GH analysts like the drawstring waistband for your best fit and flat seams to prevent chafing. Reviewers love the flattering fit and breathable, lightweight material, ideal to wear when breaking a sweat but not as thick and cozy as other picks. While we haven't yet tested this specific pair, we have tried out BALEAF's best-selling bike shorts, which received rave reviews from testers.

This tight from Athleta uses the brand's signature SuperSonic fabric, designed specifically for running, with a brushed interior. Testers with a variety of inseams tried this pair and were extremely impressed with how well it fit! One petite tester said she "was shocked that the length, hips and waist were all perfect fit for me — that's a rare occurrence!" After analysis, GH fiber scientists appreciated the fabrication of this pair with flat seams and convenient zippered pockets, but did note some shrinking after laundering.

With both convenient side pockets for your phone and wallet as well as a zippered pocket, this pair from Eddie Bauer is ideal for outdoor workouts. It's available in extended sizes up to a size 3X, and it comes in petite and tall inseams. Testers found this pair to be "generously sized" without digging in or being uncomfortable when exercising. Testers especially liked wearing this pair on long walks and hikes, saying it kept them warm "but not too hot." GH analysts love that Eddie Bauer has its own resale site to get used gear at a discounted rate. As testers noticed a bit of fuzz after machine washing and drying, be sure to turn this pair inside out when laundering, per the care label.

While most fleece-lined leggings are only available in neutral shades, this pair from 90 Degree By Reflex has over 40 different color options — as well as over 14,000 Amazon reviews! GH analysts haven't yet tested this exact style, but we have worked out in a variety of styles from 90 Degree by Reflex. Most shades feature large side pockets, but some colors are pocketless, so make sure to check before ordering. Some reviewers found they ran a bit small.

Other styles of Athleta leggings were popular among our testers for being super comfy for exercise, especially skiing or snowboarding. This pair features cozy fleece lining to keep you warm when outside in chilly temps. There are secure zip pockets to keep your keys and credit cards safe on the sides and back, which are bulkier than other picks. Available in three neutral colors, and tall, petite and regular sizing, these leggings are a great addition to your activewear collection.

Instead of saying good-bye to your favorite dresses and skirts once winter arrives, try pairing them with fleece tights for added warmth with less bulk. Available in four colors, these tights are 70 denier, which describes the fabric weight. Above 40 denier is considered opaque and not see-through, so these fleece tights are on the thicker side. Testers loved the warmth they provided, but in Lab tests, they snagged slightly easier than other tested styles.

These leggings are designed to grow with your bump while keeping you cozy and warm all winter. The thermal fleece-lined fabric helps trap heat while looking like typical maternity leggings from the outside. The top band can be folded over to be worn over and over after pregnancy. When laundering, these leggings are machine washable but not dryer safe.

The chic look of liquid or faux leather leggings can elevate any outfit, but not all pairs will keep you nice and warm. Although you can't tell by just looking at them, these chic leggings from Plush are completely fleece-lined for a soft, plush feel, as the name suggests. Note that it’s recommended to dry clean these leggings.

L.L. Bean is a brand known for its high quality products as well as a gracious return policy. This pair is available in a range of sizes with regular, petite and plus-sizes with two inseams. The PrimaLoft fabric helps provide cozy insulation that still stretches and moves with you. This pair is versatile for a variety of activities, including hiking and walking, but is especially great as a base layer for winter sports. Some reviewers wish they had a higher waist fit.
