Thermal leggings are the ultimate winter saviour for 2025 – here’s where to shop the best

According to Closer writer, Aimee Jakes, the CRZ Yoga Leggings feel really stretchy, comfortable and figure-sculpting and we can only imagine the same for the brand's thermal fleece-lined leggings. In fact, reviewers have said they're the comfiest leggings that they've ever owned. The smooth, soft brushed fabric comes with a warm inner lining, making them the best leggings for winter walks.

M&S is our go-to for all of our wardrobe basics, and the brand's leggings are certainly no exception. These trending thermal pairs come highly recommended by reviewers for their quality, fit and level of warmth. They're even made with a super-soft brushed inner layer and Heatgen™ fabric, and feature added stretch for ease of movement and ultimate comfort.

Closer writer, Jade Moscrop, recommends the Sinophant Leggings for being ultra-dark, buttery soft, never losing their shape or rolling down - and 'holding everything in nicely'. Can the same thing be said for the fleece-lined version? Well, according to reviews, these affordable leggings are a repeat purchase and keep you warm without feeling too bulky. Result.

As someone who is petite, finding flares that are the right length is a real challenge. As well as the Winter Flare Leggings, there's also the Winter Everyday High Waisted Leggings (which are a bestseller with thousands of reviews). However, the flared leggings have my heart. Reviewers love how well they fit their petite frame, as well as how versatile they are to wear. I have to say, I may just be buying a pair of these myself.

Looking for the best thermal leggings for plus-size women? Look no further. Lovall also has a curve range and, in it? These extremely cosy fleece-lined leggings. Also available to shop in petite and tall, the extra thick fleece lining and ribbed exterior work to insulate your body heat and prevent the cold. Brrr. Fans of the product loved how effective they were at keeping the chill at bay.

Due to the latest cold snap, these John Lewis leggings have quickly become a popular pick, naturally. Using a heat-retaining and body-hugging fit, these leggings are also quick-drying, moisture-wicking and anti-static. Customers said they're like a second skin. It might be worth mentioning though, that these thermal leggings might be best worn as a base layer as opposed to on their own.

We love the idea of wearing this pair of leggings with a matching sweatshirt to lounge around the house in. Or, as the base layer under a camel coat on a day trip out to the park. It's giving 'expensive' without the price tag - there's just something about an all-cream outfit that looks so put together. Either way, these thermal leggings will keep you cosy no matter what you're up to.

UNIQLO's HEATTECH thermal clothing technology absorbs and retains body heat to keep you warm. How does it work, we hear you ask? Well, fibres one-tenth the width of a human hair trap air to prevent warmth from escaping, all using a special knitting technique to create more air pockets for increased heat retention. Sound fancy? In short, fans of the product reckon they keep you warm without restricting your movement. Good enough for us.

Ideal for workouts on cold days, Marks & Spencer has your cardio covered with these Ultraheat™ thermal high waisted leggings. Selling fast over on the site, fans of these leggings are raving about how they notice a big difference in the level of warmth while wearing them on a run. The Ultraheat™ brushed fabric traps warmth, while Cool Comfort™ technology keeps you cool while working out.

Whether you're using these leggings as your everyday pair for running errands, or you need somewhere to stash your phone as you go for your daily winter run, these Amazon leggings are a total lifesaver. Reviewers loved the useful pockets for storing essentials, as well as the fantastic value for money. The soft inner lining made from fleece material also keeps your legs warm on winter walks.

If leather-look leggings are your thing, did you know they also come in the thermal version, too? We have Calzedonia to thank for this. These leggings come in a range of high-shine shades that are perfect for elevating any look, complete with thermal material inside to keep you effortlessly cosy and chic. Reviewers say they sculpt your bum, can be dressed up or down and are comfy to wear.

To follow the trend of wearing nude-coloured thermal leggings with a skirt to keep your legs warm, this pair of Asda leggings might just do the trick. They come with an elasticated waistband, soft-touch lining and are made with thermal knit fabric to make your outfits look seamlessly put together while keeping you toasty.

We wish more nude skin tones were available, however, brands such as Melanin Fleece Tights offer an inclusive range of nude sheer-look tights that are fleece-lined, so, may be one to look at if you're looking for more of a variety of nude-toned hosiery.
