Fit
The Sweaty Betty Power Legging fits with the kind of precision you expect at $110. The wide, structured waistband sits at the high-rise position without movement, rolling, or digging in — even during dynamic exercise. The compression is firm and evenly distributed across the hips, thighs, and calves, producing a genuinely sculpting silhouette that holds everything in place without the pinching or bunching that cheaper compression leggings often create.
Sweaty Betty offers three inseam lengths (24”, 27”, 31”), which is a meaningful advantage. The dedicated Petite length accounts for the proportional difference in thigh and hip measurements rather than just shortening the inseam, meaning shorter athletes get a legging that actually fits their frame rather than a cropped version of a tall-person’s pattern. Sizing runs true to size, with an honest and detailed size guide on the brand’s website.
Fabric & Feel
The 76/24 nylon-Lycra blend is where these leggings earn their premium price. The fabric has a smooth, slightly glossy finish that looks polished and moves like a second skin. Nylon at this percentage and quality delivers the buttery softness associated with luxury activewear while retaining more structural integrity than purely soft nylon fabrics — these sculpt and support at the same time, which is a difficult balance to achieve. The Lycra content provides four-way stretch and excellent recovery, snapping back to shape immediately after any movement.
The fabric is fully opaque from every angle at every bend. The bend test — squatting with bright backlight — reveals absolutely no sheerness. This is a function of both the nylon quality and the fabric weight, which is heavier than budget or mid-tier options but never feels oppressive.
Durability
Nylon-Lycra blends at this quality tier are durable when cared for properly. The Power Leggings hold their shape, compression, and color through regular washing without significant degradation. The waistband retains its structure over time, and the flatlock seams at high-stress points show no signs of wear under sustained use. Machine wash cold, use a delicate cycle, and hang dry — the Lycra content is more vulnerable to dryer heat than polyester fabrics, so skipping the dryer extends the lifespan considerably.
The honest limitation: at $110, buyers have high expectations for longevity, and pilling on the inner thighs over 12–18 months of regular wear can feel disappointing at this price point. This is a fabric reality across all high-nylon-content leggings, not a Sweaty Betty-specific failure, but worth knowing.
Value
Whether $110 represents good value depends entirely on your reference point. Compared to Lululemon’s Align Pant ($98), these are $12 more but arguably better suited to athletic performance. Compared to Old Navy’s PowerSoft ($35), you’re paying three times as much for a meaningfully superior experience. For dedicated fitness enthusiasts who will wear these multiple times per week, the cost-per-wear math works out over time. For occasional gym-goers, the investment is harder to justify.
Sweaty Betty runs regular sales and has a UK sale price that’s often 30–40% off seasonal colorways, which makes these considerably more palatable.
Who It’s For
The Sweaty Betty Power Legging is ideal for serious athletes who want premium performance alongside a flattering, refined aesthetic. It works equally well for yoga, pilates, studio cycling, running, and HIIT — a versatility that many competition-specific leggings can’t match. If you’re investing in one high-quality pair of leggings to do everything well, these belong at the top of your consideration list.
