Great fleece-lined leggings keep you warm without overheating you, and RBX’s Active Fleece-Lined Leggings do just that. During our tests, they proved incredibly versatile. They were warm enough for cold-weather workouts but breathable enough for indoor sweat sessions. And we felt comfortable wearing them during everyday activities, like shopping and lounging. Degree by Reflex’s Fleece-Lined Leggings were our favorite budget-friendly fleece-lined leggings. They earned a perfect score in every key category, proving comfortable, durable, and squat-proof. But we found them a little too tight in the waist.

Then, we researched dozens of highly rated pairs from reputable activewear brands, paying special attention to whether the brands called out any squat-proof features. The seams in traditional leggings are just uncomfortable, and visually, seamless can look quite nice. Seamless leggings elongate everything and are just more comfortable,” says Heidi Kristoffer, yoga teacher and founder of the CrossFlow Yoga App. When looking for the perfect pair of seamless leggings, you want to pay attention to the fabric, rise, fit, care and maintenance, and color. But most importantly, choose a pair of leggings that provides skin-like comfort while making you feel cute and confident. Soft and comfortable enough for lounging but compressive and structured enough for workouts, Gymshark’s Training Leggings are a versatile (and affordable) option for most wearers. We love the fabric that feels like a second skin and moves with you while offering the support you need for various activities. Beyond Yoga’s Spacedye Love the Bump Maternity Midi Leggings fit like a dream. Made of a stretchy polyester-elastane blend, the leggings feel soft and comfortable. And they seamlessly transition from activity to activity, so you don’t have to change between errands and exercising.

They come in a range of colors and sizes. And while they’re pricier, we think their quality and longevity make them a perfect investment piece. All of the Gymshark leggings we tested have a 30.5-inch inseam. The length hit our taller testers above the ankle and our shorter testers at or below the ankle. In some cases, the 30.5-inch inseam was too long for testers below 5 feet, 2. inches

We wish they came in different inseam lengths. (The flare cut isn’t forgiving when it’s too short or long.) But that’s our only complaint. They’re comfortable, durable, versatile—and worth their price point. Conroy tells us that producing a single batch of seamless leggings requires less water and material than other types of leggings. "While it might cost you a little more at the onset, seamless leggings are better for the environment and for your wallet, as they last a long time." Made of polyamide and spandex, the leggings are incredibly stretchy. And they feel like a second skin. They never pinch, bunch, or dig in; their high-rise waistband always stays in place. Despite their lightweight feel, the leggings also pass our squat test—though we noticed that you could see panty lines through them.As for length, capri leggings may be a great choice for warmer months, while ⅞ - of full-length is best for cold weather workouts, says Sariya. A pair of leggings that’s comfortable, supportive, and durable is essential for working out. But there’s nothing worse than being distracted by a see-through, sheer fabric during leg day. That’s why we researched and tested the best squat-proof leggings on the market to give you total confidence during all types of activities—whether you’re squatting, running, or even just lounging. For women looking to buy on a budget, the Hi Clasmix High-Waisted Seamless Leggings are a more affordable option. Despite their low price point, the leggings are definitely high-quality. They are made with soft performance fabrics and a flattering waistband. How We Selected the Best Seamless Leggings

Gymshark has several collections, including the Vital, Adapt, Sweat, Seamless, Elevate, Legacy, and GS Power Collections that we tested. Every line has its own blend of fabrics, but each of them includes some combination of nylon, polyester, and elastane. Stretchy, supportive, and squat-proof, Gymshark’s Adapt Camo Seamless Leggings proved great for a range of workouts. But they bunched in the knees, and their crotch area thinned in the wash. As long as your leggings are made with a flexible, durable fabric that's going to allow for dynamic movement (think jumping and lunging) they can be any rise!” says Katsafanas.After testing, we could not believe how budget-friendly these were when we looked at the price. And given the price, you might expect to lose out on quality—but not with this pair! The material is completely opaque and does not sheer out (even when squatting). And it held up throughout testing with no signs of wear and tear after one month of wear and washes. Overall, we tested 14 pairs of squat-proof leggings, but ultimately left one out of our final list of recommendations. While we did find some notable features, this pair didn’t quite make the cut.

Leggings come in a variety of different fits, and choosing the right one for you is up to personal preference and what types of activities you’ll be doing in your new pair of leggings. Some wearers prefer a high-rise fit for optimal support and coverage, while others like a cropped capri for warm weather wear. Though the leggings showed no signs of thinning, stretching, or pilling, they didn’t feel very high-quality. And we found their double-layer gusset tight and uncomfortable. Still, for their budget-friendly price, we think they’re a worthwhile buy for petite exercisers. And since they come in several sizes and colors, you can find them in a style you love. What you’ll be doing in your leggings is one of the most important things to consider before purchasing. Some Gymshark leggings are made for high-impact workouts, like HIIT, running, and cycling, while others are made for low-impact activities, like yoga, walking, or lounging. As is the case with many of the brand's most compressive leggings, this pair runs slightly small. We recommend sizing up for a more comfortable (but still supportive) fit. After one month of testing, we were impressed with how well these leggings held up, even after taking a beating at the gym.

How we tested the best gym leggings:

When you’re wearing your leggings for hours on end or working out full throttle, inner seams can irritate you, says Conroy, who adds that this is especially prevalent for those with sensitive skin. "That’s why seamless leggings are a fabulous alternative." I love seamless leggings during pregnancy because they have this ability to expand without that massively compressive top part. They grow really well with you when you’re pregnant.” says Kristoffer. Made of polyester and elastane, the leggings feel tight and compressive. And while they’re breathable enough for a sweat session, they’re also squat-proof enough for a strength-training workout. They’re versatile, seamlessly taking us from studio classes to cross-training exercises. And they held up in the wash, never sheering, thinning, or losing their shape. One of our testers found a true-to-size fit, while another noticed some bunching in certain areas like the crotch and hips. This also led her to have to hike up the waistband during several exercises—but the fit of these leggings will depend on your body type. If you’re interested in this pair, we recommend trying your normal size first and sizing up if necessary. One of the brand’s most popular styles, Gymshark’s Vital Seamless 2.0 Leggings impressed us across the board. Functional enough for high-intensity workouts and comfortable enough for daily wear, we can see why most wearers love this versatile pair.
