The Nefyn Bottom are bikini swimsuit bottoms for invigorating dips, ice-cold plunges and shorter swims when you don’t want to wear a wetsuit.

  • Made with ECONYL®, a yarn made from recycled ocean plastics
  • Two-piece style and rear clasp opening for easy changing
  • Lined stretch fabric keeps its shape for a supportive fit

The Nefyn Bottom's high performance stretch fabric retains its streamlined shape when wet and is also lined for extra support. The ECONYL® recycled fabric is also both sun cream and chlorine resistant.

The two piece style is easier to get changed in and out of at the waterside – especially if your window for discreet changing is limited! The Nefyn Bottom can be paired with the Nefyn Top or mix and matched with your existing swimwear.

How It Is Made

Recycled MaterialsECONYL® is a high performance nylon yarn made from recycled ocean plastics, disused fishing nets and landfill waste. After capturing this waste, the nylon is broken down and reformed into new fibres that are chemically identical to brand new nylon. As well as reducing emissions by 90%, it can be recycled infinitely – infinitely!

Reducing our carbon footprint
We are carbon neutral under PAS2060 and offset our Scope 1, Scope 2 and Scope 3 operations and transport emissions. We recognise that offsetting is not part of the solution but a point to pass through on a journey to Net Zero. Carbon Neutral is just a step in that journey.

We have joined the Science Based Targets Initiative which sets independent targets for us to achieve to do our bit to limit global warming to 1.5°C. Our targets are to halve our Scope 1 and Scope 2 emissions by 2025 based on 2018 base year and reduce our total carbon intesnity by 15% every year to achieve genuine net zero by 2050.
