If you're in the market for some thermal leggings to keep you toasty, you're in the right place. Whether you're after cold-weather running leggings to wear while you train for a half marathon, or warm base layers to pair with your ski jacket on the slopes, we've got you covered.
From snowboarding to winter hikes and training sessions, the right kit makes all the difference. When you wake up and it's dark and cold outside, having a pair of warm, fleece-lined leggings to slip on might just break down that first barrier to exercise: comfort. Ideally you want something warm yet sweat-wicking, so that you don't get frostbite. Other features to look out for include ankle zips, which are a godsend when you are trying to peel cold, wet leggings off you after getting caught in drizzle or snow. You might also want some functional pockets for storing your phone, keys, bank card, or mini flashlight.
Lululemon, Asics, and Nike all make great leggings for serious winter runners. M&S, Next, Decathlon, and Falke all stock cosy pairs that are ideal for your daily walk, or just layering under your clothes in freezing temps. The North Face and Sweaty Betty have the goods for snow sports base layers. We've found something for every winter activity, starting at just £14.99.
So: lace up your hiking boots, grab your fleece, and scroll on to shop the 13 top best thermal leggings picks, from high-street to high-end. (PS - we've included some great winter sale deals, too.)
Pros
- Thermo-conductive ColdGear® Infrared technology
- Internal drawcord in waistband for secure fit
Cons
This brand new launch from Under Armour boasts ColdGear® Infrared technology, which holds in body heat without adding weight or bulk. Ideal. Plus, dual-layer fabric gives you a soft, cosy brushed interior with a quick-dry exterior. We also enjoy the side drop pocket, four way stretch, and high waist on these babies.
Ewedoos Fleece Lined Leggings Women Thermal Leggings Women Winter Gym Leggings High Waisted Warm Yoga Pants with Pockets Black
Pros
- Customer top-rated
- Fleece-lined
Cons
With over 2,300 five star customer ratings, these affordable leggings from Amazon are a hit. The fleece lining is soft and cosy, and you can move about easily in them, thanks to four way stretch. One reviewer calls them "the most comfortable leggings I've bought," and others say they are "so flattering."
Lululemon Swift Speed High-Rise Tight 28" Brushed Luxtreme
Pros
- Continuous drawcord in waistband
- No inseam
Cons
Lulu's Swift Speed tights may land more on the "splurge" side of the legging category, but if you're dedicated to your cold-weather runs, these are well worth the investment. They're full length so you get maximum warm coverage, and they're designed without a pesky inseam (aka no seam chafing.) For on the go storage, you've got side drop in pockets and a back zip pocket. These have a warm brushed Luxtreme lining, Lycra for added stretch, and a continuous drawcord in the waistband that won't get lost in the wash.
adidas FastImpact COLD.RDY Winter Running Long Leggings (Plus Size)
Pros
- Reflective detailing
- Available in sizes 1X to 4X
Cons
These leggings are designed with winter running in mind, so they're up for facing the cold with their COLD.RDY technology. Back and side pockets conveniently stash your keys and phone, and reflective details provide greater visibility in the dark. We also love the lower leg zips - either for providing ventilation, or simply helping to peel them off more easily after getting caught in a drizzle. As a bonus, these leggings are made with partially recycled materials.
Pros
- Customer favourite
Cons
Crafted from Japanese Heatgen™ fabric, these leggings have an ultra soft brushed inner layer for warmth. They also absorb moisture quickly, so you stay dry. Plus, the viscose in the fabric is responsibly sourced. For £16, they can't be beat.
Pros
- Mid-rise waistband with two hidden pockets
Cons
Nike's Therma-FIT tights are "the cosy version" of their popular One leggings. Not only are they soft and comfy, but they're also sweat-wicking and non-see-through. Plus, the back is contoured into a flattering V shape.
Pros
- Seamless crotch
- Fleece lining
Cons
For under £15, you get: a warm, fleece brushed lining, a seamless crotch for reduced chafing, and sweat-wicking fabric. Customers have given these affordable togs nearly 2,000 five star ratings, which is pretty impressive for the bargain price.
Pros
- Reflective detail
Cons
ASICS is one of our top go-to labels for serious running kit, like these winter running tights. They've got a drawcord waistband, reflective detailing on the ankles, and a back pocket for storage. Buyers say they run snug, so it might be worth sizing up.
Pros
- Fleece-lined
Cons
Fleece-lined, affordable, and seamless, these pretty rose pink leggings won us over. They have a cosy ribbed texture, plus they are gloriously high waisted and stretchy.
The North Face Women's Dragline Baselayer Bottoms
Pros
- Great for snow sports
- Waistband drawcord
Cons
The North Face designed these Baselayer Bottoms with "active alpine pursuits" in mind. Fresh powder, here we come. They have a slim, but not skin-tight fit, giving you more range of motion. Built-in FlashDry™ tech helps keep you cool and dry during sweaty treks.
Stella McCartney adidas by Stella McCartney TruePace Running Leggings COLD.RDY
Pros
- Made with recycled materials
- Back zip pocket
Cons
Adidas by Stella McCartney's swirly, graphic print tights are our Shopping Editor's top pick this year. Insulated with COLD.RDY technology, these are made from warm French terry, and they also feature reflective details. A back zip pocket will hold your keys, and the draw cord waist band ensures a perfect fit. These leggings are made with recycled materials, too.
Pros
- Sweat-wicking
- Great for hiking
Cons
Sweaty Betty's fun Spacedye Base Layer Leggings are available in green, pink, purple, and blue, and lucky for us they're on major sale right now. They're high rise, breathable, sweat-wicking, and supportive - what more could we ask for? SB recommends these for outdoor activities like hiking and winter walks.
Pros
- Double layer structure
Cons
Falke, the heritage undergarment brand that's been around since 1895, knows a thing or two about great base layers. These "Maximum Warm" tights are designed to support you in cold to very cold temps, so you can get out there and enjoy your day safely. A double-layered structure keeps the body warm while managing moisture and sweat, and these are fast-drying. Plus, the contrast panels provide a subtle contouring effect.
