Are Sweaty Betty leggings actually squat-proof?

Yes — the core legging ranges are opacity-tested and use a dense 4-way stretch polyamide that holds its structure under tension. The squat-proof claim is specific to the high-compression styles; lighter-weight running and yoga fabrics are tested for opacity but use a different construction. If squat-proofing is the priority, the high-compression HIIT and strength styles are the ones to pick.

What Sweaty Betty legging is right for my activity?

High-compression styles in dense polyamide are built for HIIT, weights and studio work — they hold through dynamic movement and provide muscle support. The ultra-lightweight Italian Lycra range with compression mapping is the running option — lighter, laser-cut at hems to reduce friction. Brushed modal-blend styles are best for yoga, Pilates and low-intensity sessions. For everyday wear, the mid-weight styles work across all three.

How does Sweaty Betty sizing compare to high-street sizes?

Sweaty Betty runs XXS–XL, covering approximately UK 6–20. Sizing is accurate to UK measurements; if you're between sizes, the general advice is to size up — compression styles still provide the sculpting benefit at the larger size and will feel more comfortable day-to-day. Petite and tall inseam options are available on the core legging range for XS–L.

How should I wash Sweaty Betty leggings to make them last?

Wash inside-out on a gentle cycle at 30°C. Avoid fabric softener and tumble drying — both degrade the elastane and reduce the compression performance. Air dry flat. The key rule is that heat kills elastane — cold wash, no dryer, and the leggings will maintain their shape and compression for 2–3 years of regular use.
