Buying workout leggings should be simple, but the sheer number of options makes it anything but. Every brand claims their leggings are the best. Every product page is full of buzzwords like "buttery-soft," "squat-proof," and "four-way stretch." How do you separate marketing from reality?
This guide cuts through the noise. Whether you are buying your first pair of workout leggings or replacing a worn-out favorite, here is exactly what to look for -- and what to avoid -- so you spend your money on leggings that actually perform.
The 8 Things That Matter Most When Buying Workout Leggings
1. Fabric Composition
This is the single most important factor. The fabric determines how the leggings feel, perform, and hold up over time. Here is what each material brings to the table:
Nylon-Spandex (Best for Softness and Opacity)
Nylon is softer and more opaque than polyester at the same weight. A 75-85% nylon with 15-25% spandex blend is the gold standard for premium workout leggings. It feels smooth against the skin, resists pilling, and maintains opacity even when stretched during deep squats. This is what brands like Lululemon (in their Nulu fabric) and Avurer (in their LuxeLegs) use for their core legging lines.
Polyester-Spandex (Best for Moisture-Wicking)
Polyester repels water, making it the superior choice for heavy-sweat workouts like running, HIIT, and cycling. It dries faster than nylon and costs less to produce. A polyester-spandex blend is perfectly good for gym workouts -- it just may not feel quite as luxuriously soft as nylon against the skin.
Cotton Blends (Avoid for Workouts)
Cotton absorbs moisture rather than wicking it away, which makes cotton leggings heavy, clingy, and uncomfortable during sweat-heavy exercise. Cotton also loses its shape faster. Save cotton blends for lounging, not the gym.
The Spandex Ratio
Regardless of the base fiber, the spandex percentage determines stretch and recovery. Aim for 15-25% spandex. Too little (under 10%) means the fabric will not bounce back after stretching. Too much (over 30%) can make the leggings feel overly compressive and restrictive. The sweet spot for most women is 20% spandex.
2. Waistband Height and Width
The waistband is where most fit problems start. A bad waistband will roll, slide, or dig in -- ruining an otherwise good legging.
High-Waist vs. Mid-Rise
High-waist leggings (sitting at or above the belly button) are the most popular for good reason: they stay in place better, provide tummy support, and offer a more flattering silhouette. Mid-rise leggings sit below the belly button and work well for women who find high waists uncomfortable or restrictive. Be aware that some brands label mid-rise as "high-waist" -- check the actual rise measurement in inches if the brand provides it.
Waistband Width
Wider waistbands (3-5 inches) distribute pressure more evenly and grip more surface area, which reduces rolling and sliding. Narrow waistbands (under 2 inches) are more likely to fold over or cut in during movement. If you have struggled with waistband rolling in the past, prioritize width.
The Avurer Viva Leggings use a wide sculpting waistband with tummy control compression -- designed specifically to stay flat and stay put through every movement.
3. Opacity and Squat-Proofness
If a brand does not explicitly address squat-proofness or opacity, be cautious. The best workout leggings should remain fully opaque when stretched, bent, or squatted in -- even in bright lighting.
Before buying, check:
- Does the product description specifically mention being squat-proof or non-see-through?
- Do verified customer reviews mention the squat test or opacity?
- Is the fabric weight listed? (220+ GSM is generally safe for opacity.)
- If buying light colors, is the fabric density explicitly higher than the dark versions?
Once your leggings arrive, run the light test (hold the fabric up to a bright light and stretch it) and the squat test (deep squat in bright lighting, check from behind with a mirror or phone camera) before wearing them to the gym.
4. Stretch and Recovery
Four-way stretch means the fabric moves in every direction -- horizontal and vertical. This is essential for workout leggings because your body moves in all directions during exercise. Two-way stretch fabric only moves in one direction, which can cause the fabric to strain and thin during movements like squats and lunges.
Recovery refers to how well the fabric snaps back to its original shape after being stretched. Good recovery means the leggings maintain their fit throughout a workout and across many washes. Poor recovery means they will bag out at the knees and seat over time.
Test recovery by stretching the fabric firmly and releasing it. It should snap back immediately with no residual stretch marks or sagging. If it stays stretched, the spandex quality is low.
5. Moisture Management
For any workout that involves sweating (which is most of them), your leggings should wick moisture away from your skin to the fabric's outer surface, where it evaporates. This is called moisture-wicking, and it is a property of synthetic fabrics like nylon and polyester -- not cotton.
How quickly the fabric dries after wicking also matters. Polyester dries faster than nylon, which is why polyester-spandex leggings are often preferred for high-sweat activities. For moderate-intensity workouts, either material wicks well enough that you will not notice a difference.
6. Seam Construction
Seams affect both comfort and durability. Here is what to look for:
Flatlock Seams
Flatlock seams lie flat against the skin instead of creating a raised ridge. They reduce chafing and irritation, especially during long workouts or when the leggings are in contact with skin for extended periods. Most quality activewear uses flatlock construction.
Gusset
A gusset is a diamond-shaped panel sewn into the crotch area. It provides more room for movement, reduces tension in the seat, and eliminates the single-seam pressure point that can cause discomfort and transparency. If a legging does not have a gusset, it is likely to be less comfortable and less durable.
Seamless Construction
Seamless leggings are knitted as a single piece rather than sewn from panels. This eliminates seam-related irritation entirely and can provide a smoother, more uniform fit. The Avurer FlexFit Seamless Leggings use this construction method, which is why they feel so smooth despite their budget-friendly $17.98 price.
7. Pockets
Pockets have gone from a nice bonus to a near-requirement. Most women carry their phone during workouts, and fishing it out of a waistband or leaving it on the gym floor is not ideal.
The most useful pocket types:
- Side pockets (thigh-level): Deep enough for a phone. The most popular and most functional design. Should not create visible bulging.
- Waistband pocket (back or side): Smaller. Good for keys, cards, or AirPods. Not big enough for most phones.
- Hidden waistband pocket (interior): Small and discreet. Good for a key or locker card.
Not all Avurer leggings include pockets -- the Viva and LuxeLegs prioritize a clean, streamlined silhouette over pocket utility. If pockets are a must-have for you, check the product description before buying.
8. Length and Inseam
Leggings come in three main lengths:
- Full-length (27-31 inch inseam): Hits at or below the ankle. The most versatile option -- works for gym, yoga, running, and everyday wear.
- 7/8 length (24-26 inch inseam): Hits just above the ankle. Popular because it avoids bunching at the ankle for shorter women while still providing full coverage.
- Capri/cropped (19-23 inch inseam): Hits mid-calf. Best for warm-weather workouts or women who prefer less leg coverage.
If you are under 5 foot 4 inches, 7/8 length leggings will often fit as full-length. If you are over 5 foot 8 inches, look for brands that offer a "tall" option or specifically list the inseam length in their sizing guide.
Red Flags: What to Avoid When Buying Workout Leggings
- No fabric composition listed. If a brand will not tell you what the leggings are made of, that is a red flag.
- Less than 10% spandex. The leggings will not stretch or recover properly.
- 100% polyester with no elastane. Will not hold its shape during movement.
- "One size fits all" marketing. Bodies are different. One size does not fit all well.
- No mention of opacity or squat-proofness. If the brand does not test for it, assume the worst.
- Extremely low prices (under $10). There are diminishing returns at the bottom of the market. Under $10 typically means thin fabric, poor elastic, and limited lifespan.
- No customer reviews. Real customer feedback about fit, opacity, and durability is the most reliable buying signal.
How Much Should You Spend on Workout Leggings?
The sweet spot for most women is $25-$50. In this range, you can find leggings with quality nylon-spandex or polyester-spandex fabrics, proper construction (flatlock seams, gusset), and enough density for opacity.
| Price Range | What to Expect |
|---|---|
| Under $15 | Thin fabric, short lifespan, likely see-through. Fine for lounging, risky for gym. |
| $15-$25 | Decent budget options. The Avurer FlexFit ($17.98) and Colorfulkoala (~$23) live here and outperform expectations. |
| $25-$50 | The sweet spot. Quality fabrics, reliable opacity, good durability. The Avurer Viva ($41.98), Gymshark (~$50), and CRZ Yoga (~$32) deliver strong performance. |
| $50-$100 | Premium construction and fabrics. Lululemon ($98), Sweaty Betty (~$75). The performance gap above $50 is smaller than the price gap suggests. |
| $100+ | Luxury and brand premium. Excellent quality, but diminishing returns versus the $40-$50 range. |

- Return policy allows you to test and return if they fail your at-home checks
FAQ: What to Look for in Workout Leggings
What is the best fabric for workout leggings?
Nylon-spandex is the gold standard for softness, opacity, and stretch recovery. Polyester-spandex is better for moisture-wicking and costs less. Both are good choices. Avoid cotton for workouts -- it absorbs sweat and loses its shape.
How much spandex should workout leggings have?
Between 15% and 25% spandex is ideal. This provides enough stretch for full range of movement while maintaining shape recovery. Under 10% will not stretch properly. Over 30% can feel overly compressive.
Is it worth spending over $50 on leggings?
For most women, no. The $25-$50 range offers excellent quality-to-price ratio. The performance difference between a $42 pair like the Avurer Viva and a $98 pair from Lululemon is much smaller than the price difference. The main advantages above $50 are brand prestige, proprietary fabrics, and slightly more refined construction details.
Do I need leggings with pockets?
It depends on your workout. If you carry your phone during exercise (most people do), side pockets are extremely useful. If you leave your phone in a locker or bag, pocketless leggings offer a cleaner silhouette. Neither option is objectively better -- it is a personal preference.
How do I know what size to buy?
Always check the brand's size chart rather than relying on your usual S/M/L. Measure your waist and hips and compare to the chart. If you are between sizes, size up -- a slightly looser fit with good compression will outperform a too-tight pair that rolls down and thins out. Most brands also have return policies that let you exchange if the fit is not right.
