Sweaty Betty Buying Guide 2026: The 6 Best Activewear

These are the reason most people go to Sweaty Betty. The black full-length pair averaged 4.6 from more than 23,000 reviews when we read the page. They are 62% polyamide and 38% elastane, sweat-wicking and firmly supportive, with a side slip pocket, a zipped back pocket big enough for a phone and an adjustable internal drawcord. Sizes run from XXXS to 4XL, with 60cm and 68cm inside legs.

The recent low ratings are partly about delivery, but not only. Several long-time buyers say newer pairs do not match old ones: seams that split within a month, fraying before the first wash, a tear on the first day and loose threads at the crotch. One reviewer simply disliked the logo. Check the seams when they arrive, while you can still send them back.

The Super Soft is the studio alternative to the Power: a smoother, softer fabric (69% polyamide, 31% elastane) cut super-high in the waist with snug compression, an internal drawcord and seams placed along the leg. There is one side slip pocket and a 68cm inside leg. The page says, with refreshing candour, that the fabric is 90% squat-proof and that you should size up if you want lighter compression. Reviews averaged 4.5 from just over 3,000.

Its recent complaints are specific. One long-standing buyer found the waistband felt cheaper than the leg and did not hold up as well as older pairs, and another found the fabric a magnet for dust and pet hair. Do a squat in front of a mirror before you take the tags off.

The Stamina is Sweaty Betty’s bestselling sports bra and one of the cheapest things on the site. It is a seam-free, unpadded racerback in a rib knit (72% Fulgar polyamide, 20% polyamide, 8% elastane), with zoned stitching to stop chafing and a contoured underband. The page is unusually frank on two points: support goes up to a C cup, and you should size up. Reviews averaged 4.2 from about 2,100.

Take the sizing advice seriously. The recent product complaints are almost all about it coming up small: one 34A buyer could not get an XL on, and another gave hers to a charity shop because it was too tight to wear. Most of the other recent one-star reviews are about orders that never arrived.

For running, this is the bra to look at first. It is described as high support for high-impact work, in a lightweight 50/50 polyamide and elastane fabric, with an anti-bounce design, fully bonded adjustable twin straps that should not roll, and a hook and eye underband with a quick-release top clasp. Reviews averaged 4.2 from about 780.

The criticism is pointed, and it comes from larger busts. A 32DD reviewer found no defined cup support and a pinch at the back; a 34D called it medium support at best; another runner was cut by chafing. One owner of four older Zero Gravity bras said this replacement has fewer hooks and a narrower band, and another reported two broken clasps after one wash. Smaller cups fare better.

If the Stamina is too minimal, the Power Pulse adds shape. It is a newer medium-impact bra in Sweaty Betty’s Power fabric, with fixed moulded cups the page calls marshmallow-soft, adjustable padded straps that cross at the back, a hook and eye fastening with a keyhole detail, and seam detailing on the front. It costs £10 more than the Stamina, and reviews averaged 4.2 from about 170.

Two recent three-star reviews sum up the weak points. One owner said it is a real challenge to put on alone: she fastens it first and pulls it over her head. Another found the care labels dug in. Several one-star reviews are about orders lost or cancelled rather than the bra.

The All Day costs less than the Power and is made for gentler use: a lightweight, breathable, quick-drying legging in 80% recycled polyester and 20% elastane, with a supportive high waist and a 66cm inside leg. It suits walks, errands and stretching classes, and it is the easiest way into Sweaty Betty’s leggings at a lower price.

It is also noticeably less loved than the Power. Reviews averaged 4.0 from about 670, and recent low ratings say the newer version has changed: side seams added, a shorter leg, a waistband that digs in and a feel that does not match older pairs. A 5ft 9in buyer found them short. If you already own an older All Day, do not expect a like-for-like replacement.
