Finding a sports bra that genuinely supports you through runs, gym sessions and long days outdoors can transform how confident and comfortable you feel. The SWEATY BETTY Women’s Power Pulse Bra is designed to be that kind of go-to piece – supportive, soft and ready to move with you from the studio to the trail.
Why a good sports bra matters for active women
Whether you are running, hiking, lifting or flowing through a yoga class, breast support is not just about comfort – it is about protecting delicate ligaments from repetitive strain. Poor support can lead to soreness, posture issues and a reluctance to move as freely as you would like.
A well-chosen sports bra will:
- Reduce bounce and strain on breast tissue
- Keep you comfortable on longer sessions
- Help manage sweat and body temperature
- Boost confidence so you can focus on your activity, not your kit
The SWEATY BETTY Women’s Power Pulse Bra has been created with these points in mind, using the brand’s signature Power fabric to offer a balance of support, stretch and breathability.

Meet the SWEATY BETTY Women’s Power Pulse Bra
The Power Pulse Bra uses Sweaty Betty’s stretchy, sweat-wicking Power fabric blend (62% polyamide, 38% elastane). This combination is known for its supportive yet flexible feel, making it well suited to mixed training: think running to the gym, circuits, then a cool-down walk home.
Key design details include:
- Soft moulded cups – fixed, marshmallow-soft cups that provide shape and breathable coverage without feeling heavy.
- V-neck front – a more feminine neckline than many high-coverage sports bras, while still maintaining support.
- Adjustable padded shoulder straps – cushioning helps reduce pressure on the shoulders, while adjustability lets you fine-tune the fit.
- Crossover back straps – the crossover style improves stability and keeps straps in place during dynamic movement.
- Hook-and-eye fastening with keyhole detail – a classic bra closure for easy on/off and a custom band fit, combined with a small keyhole opening for ventilation and style.
- Feminine seam detailing – shaping seams for a flattering silhouette under kit and casual wear.
Together, these features position the Power Pulse as a versatile, medium-support style that can handle a wide mix of activities, from strength training to weekend hikes. For a closer look at how it performs in real sessions, you can read our in-depth SWEATY BETTY Women’s Power Pulse Bra review.
Understanding sports bra support: is the Power Pulse right for you?
Support in sports bras is mainly driven by three elements: the band, the straps and the cups. The SWEATY BETTY Women’s Power Pulse Bra leans on all three.
The band: your main source of support
A firm band is crucial because it carries most of the weight. With the Power Pulse, the hook-and-eye fastening allows you to adjust the band more precisely than a pull-on crop style. If you are between sizes or your body changes across training cycles, that extra adjustability is very useful.
When trying it on, the band should feel snug on the loosest hook. As the fabric naturally softens over time, you can then move to tighter hooks to maintain support.
Straps and crossover back for stability
The adjustable padded shoulder straps on the Power Pulse help you dial in length and reduce shoulder fatigue. The crossover back style spreads tension more evenly and resists slipping during movement – useful for running, skipping and strength work that has you changing position frequently.
Moulded cups for shape and coverage
The fixed soft moulded cups provide light shaping and prevent that “uniboob” feeling some compression bras create. They also give modesty under thinner gym tops or running tees without the faff of removable pads. If you like a bra that can double as a standalone top for summer runs or studio classes, this design is a strong contender.
How to choose the right size in the Power Pulse Bra
Sizing can make or break any sports bra. Even the best design will underperform if the fit is off. Here is a simple approach when you are considering the Power Pulse or similar styles:
- Start with your everyday bra size as a baseline. Most women will be close to their regular size in Sweaty Betty’s underband-and-cup systems.
- Check the band first: it should be firm but comfortable, not riding up at the back when you move your arms overhead.
- Look at cup coverage: your breast tissue should sit fully inside the moulded cups, with no bulging over the top or sides.
- Adjust straps last: shorten or lengthen them so the cups sit flat and the crossover does not pull the band upwards.
If you are between sizes or prefer a compressive fit for running, many people find going slightly smaller in the band (while adjusting the cup accordingly) gives a more locked-in feel. For lower-impact days, your regular size is often the sweet spot.
When to use the Power Pulse vs other sports bras
The SWEATY BETTY Women’s Power Pulse Bra is best seen as a multi-sport, everyday training bra rather than a specialist marathon-only piece. Consider it for:
- Gym sessions and circuits
- Short to mid-distance runs
- Fitness classes and studio work
- Day hikes and active travel
If you do ultra-distance running or very high-impact sports regularly and are fuller-busted, you may want a dedicated high-support bra in rotation. For many women, though, a medium-support piece like the Power Pulse is the workhorse that sees the most weekly wear.
Fabric, sweat management and all-day comfort
The 62% polyamide and 38% elastane mix used in Sweaty Betty’s Power fabric is designed to wick sweat, dry quickly and move with your body. Polyamide is durable and smooth against the skin, while elastane gives the stretch and recovery you want from a performance bra.
Because the cups are soft and lightly structured rather than heavily padded, the Power Pulse avoids feeling bulky under layers. This makes it a good option when you might wear it all day – for instance, travelling to a walking weekend, wearing it on the trail, then straight into the pub afterwards.
Care and washing tips to keep your sports bras performing
Elastane-rich fabrics can lose their snap if they are overheated or over-washed. To get the most out of any performance sports bra – including the SWEATY BETTY Women’s Power Pulse Bra – a few simple habits help:
- Machine wash cool (usually 30°C) and avoid hot cycles which can degrade elastic fibres.
- Use a mild detergent and skip fabric softener, which can coat fibres and reduce wicking.
- Close the hook-and-eye fastening before washing to prevent snagging on other garments.
- Air dry flat or on a rack; avoid tumble drying where possible.
- Rotate between a few bras if you train most days, so each one has time to fully dry and recover its shape.
Look out for changes in fit over time. If the band feels loose even on the tightest hook, or you notice more movement during runs, it is probably time to refresh your kit.
How the Power Pulse compares to other Sweaty Betty options
Sweaty Betty offers a number of tops and sports bras that complement or provide alternatives to the Power Pulse. Here is how a few related pieces stack up in terms of use and style.

Comparing this with the Power Pulse can highlight subtle differences that might matter to you, such as neckline, back style or how it layers under your favourite tops.
Pairing your bra with the right tops and bottoms
Your sports bra does not work in isolation. Layering it under suitable tops and pairing it with comfortable shorts or leggings can make a big difference to how prepared you feel for training or heading outdoors.
The SWEATY BETTY Women’s Revive Crew Neck Sweatshirt is a relaxed, layer-friendly top that sits comfortably over fitted bras like the Power Pulse. If you like the idea of throwing on a soft layer before and after sessions, you might want to read about the SWEATY BETTY Women’s Revive Crew Neck Sweatshirt and how it works in a training wardrobe.
For warmer training days, the SWEATY BETTY Women’s Breathe Easy Running T-Shirt is built as a light, breathable layer that lets your bra do its job underneath while helping with airflow and sweat management on top. You can find more on this in our SWEATY BETTY Women’s Breathe Easy Running T-Shirt review.
If you are building a head-to-toe outfit for gym, running or active travel, a pair of comfortable shorts is just as important. The SWEATY BETTY Women’s Revive Boxy Shorts offer a looser, easy-going fit that pairs nicely with more supportive bras and fitted tops. To see how they perform for lounging, light training and warm-weather walks, have a look at our review of the SWEATY BETTY Women’s Revive Boxy Shorts.
Building a versatile activewear system
When you zoom out from any single bra, it helps to think in terms of a small system of kit that covers your week. A practical setup for most active women might include:
- One or two medium-support bras like the Power Pulse for mixed training and everyday exercise.
- A higher-support bra from the Power range or similar if you regularly run or do high-impact sports.
- A couple of breathable tops such as the Breathe Easy Running T-Shirt for layering and sweat management.
- Comfortable bottoms – shorts or leggings that do not ride up or chafe.
- An easy layer like the Revive Crew Neck Sweatshirt to throw on before and after training or on cooler days outdoors.
The SWEATY BETTY Women’s Power Pulse Bra makes most sense as the central, do-most-things bra in that system. It is comfortable enough to wear beyond your session, supportive enough for a wide range of activities and styled to work both under kit and as part of an athleisure outfit.
