I orderd this sports bra due to fighting so much with my previous cross back one to get in & out of one. Also didnt want to pay the ridiculous sports bra prices especially if your on the larger cup & back size. The reviews was very positive to read so took the chance to buy it. First impressions not so great due to not looking high impact, no padding just material. I'm a 34F & ordered 36F, very small back fastening but bigger with the extension. Found a 'light bulb' solution without using extension, fix it in front first then twist round to pull the straps on. Did a test in front of a mirror of star jumps & running on the spot! Its flattens your upper body & is solid. What a magic sports bra. Love the soft thick straps, no marks left.

Delivery was really fast.Pros - The material is strong, the bra has a lovely pattern, it comes with a strap extenderFor your back and you can adjust the shoulder straps to pull up too! Value for money. I usually spend double on my Bras.I’m glad I read all of the reviews, I usually find it difficult to find bras that will pass the jump test, are tight enough, and comfortable - (I’ll be using it for daily exercise.) This ticks those boxes - Just ensure you SIZE UP. I bought the biggest cup they have ‘J’ and went up a size in my back to a 38J (I’m usually around a 36K in normal bras) . without the extra strap it’s a little tight, but I lose the hold if I add the extender as my back is a smaller ratio to my cup (nice to know it’s there anyway)Cons: there is a very slight spillage on the side and the top bulges just slightly. But nothing too bad. I may just to wear a light material sports bra over this one (I’ve previously worn 3 at one time, so again not a problem).Great buy overall for price, coverage, comfort And hold - I’m sure it’ll pass the run test and if it does, I’ll buy another :)

The bra itself if great. I have started a new fitness programme that has a lot of jumping involved and being a 40G something supportive was needed. The cup size is fantastic, I feel supported with little to no bounce. The back size is extremely small. I used the extension given for the first wear, photo included, poor and not fit for purpose. As it is elastic it doesnt give any support and has stretched after one use. Second use I used my own extension and it was so much better. The fact that an extension is included says the supplier knows of the problems with sizing.Would order again and recommend to other but would advise them to get their own extension first.

Tried it out for the first time at my gym appointment today.Lovely soft material, full bust coverage and fits great.The wide straps don't dig in either. Easy to adjust the straps - just like a normal bra.The band was a little small but with the extender it was perfect.Comfortable sports bra, I bought my normal size 36h and will be buying another.

Absolutely love it! It is my favourite one. It provides full support and coverage. It acts as a minimiser and gives a very smooth shape under my clothes. As a woman with a large upper body, it makes me uncomfortable to have spillage. It solves this problem completely.

Bought a 38e size which was nearest I could get to my36 e bra size. It is a good fit but the chest girth was really tight but thankfully you do get an extender that can add another one or two inches onto girth around chest. When added the extender it fitted really comfortably. The bra actually could pass for a short gym top if you went to a gym,it doesn’t look too much like a bra but a nice short gym top. But obviously that’s personal preference. When I went running I felt supported in the boobs but there is a slight movement, it’s not like being in a strait jacket, but the slight movement is ok. I think this is a good buy for the money it looks attractive and you get support too.

I recently tried this high-impact, no-bounce sports bra designed for large busts, and it really stands out—especially with the included bra extender that makes it feel custom-made.✅ What I Love • Firm, non-bounce support: Built without underwire but with a snug band and wide, padded straps, it keeps the chest tight and stable during running, HIIT workouts, and jumping routines. • Bra extender included: The hook-and-eye extender adds a few extra centimetres to the band, ideal for fluctuating sizes, maternity, or just better comfort—an absolute lifesaver • High coverage + breathable fabric: Full-coverage cups and stretch breathable material give great shape without compromising airflow or comfort.
