Heart, lungs, and legs—these are the engines needed for running. The body’s built-in insulation protects the first two, but the gams present a lot of surface area that’s vulnerable to wind and cold. The winter running tights and pants in this review effectively sheltered our testers from the elements, while providing muscle support, pockets for storing everything from fuel to phones, and reflective overlays for safety in low-light conditions. Winter running is noticeably better when you keep your engines and your (wink) chassis warm and protected.

Sizes: XS-XXL
Pros and Cons
+ Unmatched fabric comfort
+ Snug, supportive fit
– High compression feel is not for everyone
Unlike other tights that you want to pull off seconds after returning from a run, these On Running models were comfortable for extended post-workout stretching or even lounging. The 74 percent recycled polyester, 26 percent elastane fabric is buttery smooth, with reassuring muscle support that was especially noticeable when descending steep terrain. The fit is close, bordering on too tight for some testers’ liking, but the stretch was so great that everyone gave them high marks. The brushed fleece interior effectively wicks moisture, and details such as a comfortable flat drawstring, reflective patches, and abundant pockets also earned praise for these winter running tights.

Sizes: S-2XL
Pros and Cons
+ Zippered and unzippered pockets
+ Reflective overlays
– No liner
Whispery light, with small waist pockets (one with a zipper) and a straightforward flat waist tie, these basic running tights offer everything you need and nothing you don’t, and provided more than adequate comfort and protection for most runs. The four-way stretch fabric felt good against bare skin and kept testers warm on mildly cold runs, but did not provide enough insulation for comfort at temperatures below about 30 degrees Fahrenheit. There’s no place to stash fuel, water, or a phone, but pair these with a pocketed jacket or running vest and you won’t miss the storage on the running pants.

Sizes: S-XL
Pros and Cons
+ Ample no-bounce pockets
+ Unrestricted movement
– No liner
With two small interior pockets, four side pockets, and a back pocket, you might expect these running tights to feel bulky—but they never did. The unlined (save for a double layer of fabric up front) and high-stretch fabric provided unrestricted movement and enough warmth for temperatures down to freezing. In frigid weather, the Janji tights offered a little less protection than we hoped, but, on the flip side, they stayed comfortable when temps climbed into the 50s. The flat drawstring ties on the outside, so you can load all those pockets and still snug the waist up comfortably.

Sizes: XS-XXL
Pros and Cons
+ Zippered and unzippered pockets
+ Reflective overlays
– No liner
Reduced daylight in the winter months means more time running in dark and semi-dark conditions, which is when the DayGlo orange color panel and abundant reflective features on these tights added reassuring visibility. With dark comes cold, and the tight’s soft, medium-weight fabric was up to the task of keeping us warm after the sun set. The smooth waistband and flat drawstring were always comfortable, and a small zippered pocket, plus another for larger items, carried our keys and phones securely.

Sizes: XS-XL
Pros and Cons
+ Relaxed fit
+ Tester favorites pre- and post-run
– Too loose-fitting for some tastes
“These pants were comfortable during workouts, and I liked them even more for stopping at the donut store afterwards,” said one tester. Others were less enthusiastic about the roomy fit, with one tester suggesting he’d only wear them when he takes up yoga classes. The lightweight fabric provided enough warmth on cool to cold days, and felt smooth against bare skin, but the protection was too skimpy for frigid or windy conditions. Still, the Victory Pants earned high overall scores for their deep, zippered pockets, ankle zips that extend almost to knee height, a soft waistband, and a good-looking embroidered logo.

Sizes: XS-XXL
Pros and Cons
+ Thick, soft, warm fabric
+ Lined and unlined options
– Phone pocket is a tight fit for most models
One tester wore the Tracksmith running tights for an hour-long, 40-degree run in steady rain and happily reported that they stayed comfortable throughout. The 80% Polyamide, 20% Elastane fabric, combined with a brushed inner layer, is a little heavier than most other tights, but with that heft comes outstanding weatherproofness, muscle support, and warmth. The three back pouches were easy to reach, but even the largest pocket didn’t accommodate large phones. The model we tested included a supportive liner that adds extra warmth where you need it most, but you might opt for the no-liner version if you prefer to wear running shorts underneath.
Consider the relative advantages of close-fitting tights and looser-fitting running pants. Stretchy tights do more than just insulate—they also provide muscle support and can help improve circulation. In moderate temperatures, typically down to the low 20s Fahrenheit, tights work fine on their own. When temperatures dip below that, they’re easily combined with wind pants or a heavier outer layer, creating a highly protective combination.
On the other hand (leg?), a pair of lightweight or midweight running pants offers improved modesty, comfort, ease of getting on and off, and freedom of motion. A downside is that the extra bulk means pants do not work as well for use as base layers. Running pants often provide roomier pockets, but what you place in them will bounce around more than whatever you can wedge into the pockets of tights. Pants also have the edge for non-running versatility—unless you’re cool with hanging it all out in the post-run coffee shop.
Once you know your style, fit and heat regulation top the list of priorities. Make sure the pants or tights neither constrict anywhere nor are too loose so that they get in the way or fail to stay up. The amount of insulation you need varies significantly from person to person. Consider the conditions you’ll be running in most often and whether you tend to run hot or cold. The best running tights keep you from freezing while you’re warming up then breathe and vent well enough that you don’t overheat when you’re working hard.
