The Sweaty Betty Women’s Power Medium Impact Tank Top is a fitted training vest that blends the look of a sleek gym top with the function of a medium-support sports bra. It sits firmly in the premium end of activewear, using Sweaty Betty’s well-regarded Power fabric for a body-hugging, supportive feel.
Designed for gym, training and fitness work, it aims to cover everything from strength sessions to spin classes where you want support without the bulk of a separate bra and top. With removable foam cups and an adjustable T-bar back, it is clearly geared towards women who take their training seriously and want kit that stays put when they move.
There are no user reviews available yet, so this is very much a spec-led assessment. On paper, though, the mix of technical fabric, built-in support and adjustability makes it an appealing option if you like streamlined, performance-focused gym wear.
This tank is best suited to women who spend a lot of time in the gym or in structured fitness classes and prefer a clean, streamlined look rather than layering a bra under a loose vest. If you like your kit to feel secure, sculpting and performance driven, the Power Tank is aimed squarely at you.
With a price that reflects Sweaty Betty’s premium positioning, it is not the cheapest option in women’s training tops. It makes most sense if you value technical fabric, a flattering cut and built-in support over pure budget, and you are happy to pay for those extras.
The medium-impact construction is ideal for strength training, circuits, indoor cycling, reformer Pilates and general fitness work, as well as brisk walks and lower-impact runs for smaller cup sizes. If you regularly do high-impact running or plyometrics and have a larger bust, you may prefer to pair it with a higher-impact bra or look for a more supportive alternative.
It is also a sensible pick for those who dislike fiddly strap arrangements. The adjustable T-bar looped back keeps things neat, helping the tank stay in place during overhead moves and floor work, which will appeal to both keen gym-goers and class regulars.
The standout strength of this tank is the use of Sweaty Betty’s Power fabric. The high elastane content gives it a close, sculpting fit that moves easily with you during dynamic workouts, while the quick-drying, sweat-wicking properties help you stay comfortable when you start to heat up.
The built-in medium-impact support with removable foam cups means you do not necessarily need a separate sports bra for many gym sessions. This keeps your outfit simpler, reduces bulk and gives a smoother silhouette under other layers, which many gym-goers will appreciate.
The looped back with adjustable T-bar strap is another thoughtful touch. Being able to tweak the strap length lets you fine-tune the fit, reduce bounce and stop straps slipping during overhead presses, burpees or yoga flows.
Finally, the overall design feels versatile. It looks polished enough for studio classes and everyday athleisure use, while still being performance driven enough for real training.
The most obvious drawback is that this is a premium-priced tank in a crowded activewear market. You can find basic gym vests and low to medium-impact bras for less, so the value really hinges on how much you want the integrated, higher-spec feel of the Power fabric and Sweaty Betty branding.
Medium-impact support will not be enough for everyone. Runners with a larger bust or anyone doing lots of jumping and HIIT may still need a dedicated high-impact bra underneath, which slightly undermines the simplicity of the built-in support.
Because the fabric is a dense, stretchy polyamide-elastane blend, it is also more of a performance top than a breezy, relaxed vest. If you prefer a looser, more breathable feel or something you can easily throw on and off mid-session, the close, compressive fit might not be your style.
Finally, there is no mention of additional ventilation features or mesh panels. While the fabric is sweat wicking and quick drying, those who run hot may miss extra airflow on very intense sessions.
In day-to-day training, the Power Tank is likely to feel snug and confidence boosting. The stretch fabric hugs the body, so you do not have to worry about it riding up during squats, planks or inversions. The adjustable T-bar back helps keep the straps centred and comfortable, whether you are lifting, stretching or on the spin bike.
The removable foam cups give you options. Leave them in for more shaping and modesty on chilly days or busy gym floors, or take them out if you prefer a lighter, less structured feel. Because the cups are removable, washing and drying are a bit easier too, as you can take them out to prevent creasing.
The quick-drying, sweat-wicking fabric means the tank copes well with back-to-back sessions or busy weeks. It should dry fast overnight after a wash, which is handy if you rotate a small number of gym outfits. The smooth, synthetic fabric is also straightforward to care for using a cool wash and air dry.
Thanks to its fitted cut, it layers cleanly under a hoodie or lightweight jacket for the journey to and from the gym. Around the house or on casual days, it doubles as an athleisure top with leggings or joggers, although the supportive fit does make it feel more “gym kit” than loungewear.
Performance-wise, the Power Tank is all about support and moisture management. The 62% polyamide and 38% elastane blend gives a firm, compressive feel that holds you in without completely restricting movement. For static strength training, studio work and moderate-impact cardio, that medium-impact support strikes a sensible balance between comfort and stability.
The sweat-wicking, quick-drying fabric is an important feature if you regularly push your heart rate up. It should draw sweat away from the skin reasonably quickly and dry faster than cotton-based tops, helping to reduce that clammy post-workout feeling and making it more practical for intense gym sessions or back-to-back classes.
Removable foam cups add another performance angle. They give gentle shaping and extra coverage, which can be reassuring during stretch-heavy classes or when bending and twisting. Because they are not stitched in, you can easily remove them to reduce bulk or to wash separately, although you will need to take a bit of care when re-inserting them so they sit flat.
The looped back with adjustable T-bar strap is a functional design choice as well as a style one. It helps keep the straps secure between the shoulder blades, improving freedom of movement through the shoulders while reducing the risk of slipping straps. This makes it well suited to upper-body strength work, yoga, Pilates and any training that involves a lot of arm mobility.
Overall, the feature set is focused and purposeful rather than flashy. There are no unnecessary extras; instead, you get a solid combination of support, stretch and moisture management that meets the demands of regular gym and fitness use.
At £45, this is firmly in premium territory for a training tank, especially when you can pick up basic gym vests and separate low to medium-impact bras for less. The justification lies in the quality of the Power fabric, the integrated support and the thoughtful adjustable back design.
If you train several times a week and like to invest in kit that feels supportive, washes well and holds its shape, the cost will be easier to justify. The combination of compressive fit, sweat management and removable cups gives it more functionality than a simple cotton vest, and Sweaty Betty’s reputation for durable, flattering activewear adds peace of mind.
However, if you are on a tight budget or only exercise occasionally, there are more affordable ways to get something functional. In that case, this tank is more of a treat than a must-have, and its value depends on how much you care about premium feel and brand styling.
With no user reviews yet to confirm long-term durability, the value proposition rests mainly on the brand’s track record and the strong spec. For regular gym-goers who appreciate high-quality activewear, it represents reasonable value; for casual users, it may feel expensive for what it is.
The Sweaty Betty Women’s Power Medium Impact Tank Top is a polished, performance-focused choice for women who want their gym wear to work as hard as they do. Its compressive Power fabric, built-in medium-impact support and adjustable T-bar back make it a confident option for regular strength training, classes and general fitness work.
It is not the best fit for everyone. High-impact runners, those with a larger bust needing maximum support and anyone who prefers loose, breathable layers may find it less suitable. Likewise, the premium price will not appeal if you simply want a basic vest to throw on for the odd workout.
For committed gym-goers who enjoy premium activewear, though, this tank earns its place. If you are looking for a sleek, supportive top that can handle most indoor training without needing a separate bra, the Power Tank is well worth considering.
