Feel the feeling of a guilt free summer with our Mabyn tube bikini top, available in four luscious colour options. Mabyn, like all of our products is made out of regenerated ocean waste that’s been milled into the buttery, softest and highest quality fabric that provides:

  • excellent UV protection (UPF 50+)
  • is sun cream and oil resistant
  • is durable, lightweight and breathable

Helping you to enjoy yourself without the worry of contributing to harming the environment! The gold accent details are made from the highest quality nickel-free metal so you don’t need to worry over being burnt whilst topping up your tan and can just focus on looking stylish both in and out of the water.

The tube bandeau silhouette allows for a classy option with added support from a detachable halter neck tie. The back tie this allows you to customise the fit and support level. Our model is a size 8-10 and wears a 34C in bra sizes and fits into both our Small and Medium tube tops, but would recommend sizing up if you want fuller coverage. Our kini's are designed to be HAND WASH only in cold water and to be line dried.



Ensuring the fit of our bikinis is perfect is our top priority and we design all of our Swimwear in-house in Cornwall and work extremely closely with our manufacturers based in Sri Lanka who has the highest quality equipment and skilled machinists to ensure an exceptional fit and luxury quality.

As you know protecting our planet and ensuring we use sustainable practices is our main ethos, so from using regenerated materials to making sure our suppliers pay their workers a fair wage to the eco-friendly packaging we use, we like to think we are doing a pretty good job. If you’d like to know the details of all of our sustainable and ethical practises we have a page dedicated to our efforts right HERE.
