I felt like Bouncedown bathers were made for my body type. They provide secure support around the bust area, which held strong when I participated in my triathlon and surfing events.The bathers have a flattering design, unique clips, and very comfortable straps. I was also impressed with the durability of the material which could withstand salt, chlorine and sand. It's lovely to see a new brand that focuses on high support and great style!"

This swimsuit is so great! It's not only a flattering fit, but also incredibly comfortable - especially for the big jugs! Finally a swimsuit that is both nice to look at and practical for when I want to be more active. The support and coverage was perfect for me, and I feel secure and relaxed whether I'm doing laps in the pool or dipping into the ocean. I’ve finally found a swimsuit that makes me feel confident and carefree - thank you BounceDown!
— Anya
I feel so secure! I am loving the support of the bra part. I wore my BounceDown bathers under my gym gear this morning, which I never do, so I could just jump in the ocean afterwards! I usually have to wear my sports bra and change into my bathers as a regular one-piece simply cannot do the two jobs! These bathers solve that problem.
— Anna
I have got quite a long body, so ideally for me the swimsuit would be a little longer.  That said, it still fitted really well and felt really comfortable everywhere. It felt so supportive on my boobs and when I jumped, ran and swam - they didn't move at all!
— Nicola
I love my new BounceDown bathers. As a woman with a bigger bust, I have been able to finish triathlons without having to wear a sports bra under my bathers. This innovative product really fills a gap in the market and has enabled me to take part in water sports while being confident and comfortable.
