The best leggings are opaque when you bend, stay put when you move, feel smooth against the skin and keep their shape after many washes. Which pair that is depends on what you do in them: lifting, running, yoga, travelling, working from home or simply living in them on a Sunday.
This guide is a buyer's guide rather than a product ranking. It explains the fabrics and constructions that matter, the waist and length options, how to match leggings to activities and budget tiers, and how to test and care for them. Use it to filter any range, whether you are shopping on the high street, online or from a specialist sports retailer.
Quick picks: which leggings for which purpose
| If you want... | Look for |
|---|---|
| Everyday comfort | Soft, brushed or cotton-blend fabric with a wide, flat waistband |

What to look for
Fabric composition
Most performance leggings are a blend of nylon or polyester with elastane. Each has its character.
- Nylon-rich blends feel smooth and soft, often with a slightly cool, silky finish. They are popular for yoga and everyday wear.
- Polyester-rich blends tend to wick moisture quickly and resist wear, which suits running and high-intensity workouts.
- Elastane (also called spandex or Lycra) gives stretch and recovery. A healthy amount is needed for shape retention.
- Cotton blends are soft and breathable but hold moisture, so they suit low-impact wear more than sweaty workouts.
- Recycled fibres are increasingly common. Check that brands provide clear information about what they use.
Weight and opacity
Fabric weight affects coverage, warmth and compression. Heavier fabrics are more opaque and supportive, while lighter ones are cooler and more flexible. The key test is opacity: bend over in good light in the fitting room, and check the seat and thighs. Light colours and thin fabrics are most likely to show through.
Compression and support
Compressive leggings hold muscles in place and feel secure during high-impact exercise. Softer, less compressive leggings suit relaxed wear. If you are not sure, try a mid-level compression.
Seams and construction
- Flat or bonded seams reduce chafing.
- Gusseted crotch improves comfort and durability.
- Squat-proof stitching at stress points lasts longer.
- Seamless knit is smooth and stretchy, but can be thinner.
- Contoured seams shape the leg, and some people prefer a simpler, seamless back.
Waistband
A wide, high waistband is the most popular choice because it sits flat and stays in place. Check that it does not roll down when you bend, dig in when you sit, or gape at the back. A hidden pocket for keys or a card is helpful for walkers and runners.
Length
- Full length for general wear, yoga and winter.
- 7/8 or ankle length for a neat line with trainers.
- Capri for warmth without full length.
- Biker or short for summer and high-intensity sessions.
Check the inseam if you are short or tall. Some retailers offer regular, petite and tall lengths.
Pockets
Side pockets that fit a phone are more useful than small ones. Make sure the pocket lies flat and does not bounce.
Best options by need and budget tier
Entry-level
High street and supermarket leggings are ideal for casual wear, lounging and low-impact workouts. Check opacity and shape retention. Heavy training may reveal weaknesses in seams and recovery.
Mid-range
Often the best value for regular exercisers. You should find better fabric, flat seams, reliable opacity and a wider choice of lengths.
Investment
Specialist sportswear can offer refined fabrics, advanced seam construction and extended sizes. If you wear leggings daily or train frequently, the better wear and fit can justify the higher tier. Always check returns policies, since fit is personal.
By activity
Gym and weights
You need opacity at depth, so squat in the fitting room. A high, secure waist and flat seams prevent chafing and shifting.
Running
Lightweight, breathable fabric, a secure waistband and a phone pocket. In winter, choose brushed or thermal fabrics, and for dark evenings look for reflective details. If you run outdoors in daylight, apply sunscreen to your face and neck first; our guide to the best sunscreen for face explains what to look for in a formula that will not sting in sweat.
Yoga and pilates
Soft, stretchy fabric with four-way stretch and a waistband that stays flat when you invert. Avoid fabrics that are too slippery or too thick.
Travel and everyday
Opaque, breathable, wrinkle-resistant fabric that you can wear for hours. Choose neutral colours and a comfortable waistband. A pocket is a bonus.
Smart-casual
Thicker fabrics with a smoother, structured finish look closer to trousers. Wear with a long jumper or a tailored blazer.
How to test leggings before you commit
- Check opacity. Bend, squat and stretch in front of a mirror in bright light.
- Move. Do a few lunges and check the waistband stays put.
- Sit. The waistband should not dig.
- Check the seams. Run a hand along the inner thigh for rough spots.
- Wash test. After the first wash, check for bobbling, fading or shrinking.
For online orders, keep tags on until you have tested them, and read reviews for comments on opacity and sizing.
Sizing and fit notes
Sizing varies by brand and fabric. Measure your waist, hips and inseam, and compare with the size chart. Leggings should feel snug, not restrictive. If you are between sizes, think about the activity: size down for compression, size up for comfort. Extended sizing is now more common, so look for retailers with inclusive ranges.
Care and longevity
- Wash inside out at a low temperature.
- Use a gentle detergent and avoid fabric softener, which can coat fibres and reduce stretch and wicking.
- Avoid high heat in the tumble dryer. Air drying preserves elastane.
- Wash with similar fabrics to avoid pilling from zips and Velcro.
- Rotate pairs so that fabric can recover.
- Wash after each workout to prevent bacteria and odour.
Finishing the look after the workout
Leggings often go from the gym to errands, so a quick refresh matters. Cleansing wipes and a light mascara keep you looking put together without a full routine. If you wear mascara to the gym, a waterproof formula helps; our best mascara guide explains how to choose between lengthening, volumising and waterproof formulas.
Common mistakes
- Not testing opacity. Thin fabric can reveal more than you expect.
- Buying for looks, not purpose. Match fabric and fit to the activity.
- Choosing the wrong size. Too tight can be uncomfortable. Too loose slips.
- Ignoring seams. They matter in longer workouts.
- Washing on high heat. It damages elasticity.
- Overlooking length. A hem that is too short or long ruins the line.
Practical UK context
British weather suggests layering. Brushed or fleece-lined leggings cope with cold mornings, while lightweight, quick-drying fabrics help in damp conditions. Reflective details are practical for winter runs and walks. Keep a pair of cropped or biker styles for warmer months and indoor classes.
Frequently asked questions
What are the best leggings?
The best leggings are opaque, supportive and comfortable, in a fabric suited to what you do. Look for a good elastane content, a flat, high waistband and strong seams.
How do I know if leggings are squat-proof?
Try them in good light and squat in front of a mirror, checking the seat and thighs. Thicker, denser fabric and darker colours are more likely to stay opaque.
What fabric is best for leggings?
Nylon-rich blends feel soft and smooth, polyester-rich blends wick moisture well, and both usually contain elastane for stretch. Cotton blends are comfortable for low-impact wear.
How do I stop leggings rolling down?
Choose a high, wide waistband with a flat fit and a size that is snug but not tight. A gripper or silicone lining at the waistband can help.
In short
