If you’re looking for a new swimsuit but you want it to be sustainable and environmentally friendly, here’s what you need to know.

Swimwear used to be one of fashion’s most unsustainable area’s due to the materials needed in order for it to perform well. Plastic-based synthetic fibres like nylon and polyester are popular because they are quick dry, stretch well, and wick moisture. But Polyester and nylon both come from petroleum and their production needs a large amount of water and energy, plus they don’t biodegrade.

Thankfully there are new fabrics making waves, both on the high street and with small sustainable brands. ECONYL is a recycled nylon fabric made from a combination of ocean plastic and nylon waste. This gives another life to textiles that would normally go to the landfill or end up in the oceans, like fishing gear- which makes up 27 per cent of marine litter. REPREVE is a performance fiber made from recycled plastic bottles.

ECONYL can be made using anything from fishing nets to carpets and although nylon is still involved in the process, it’s certainly better for the environment in a recycled form than thrown away, plus it is infinitely recyclable. Econyl saves on the demand for crude oil, plus it creates a nice, clean feel that is indistinguishable from virgin nylon.


An important factor in living more sustainably is how long you keep your clothes for. When washed properly ECONYL and REPREVE will have a longer life than their plastic counterparts so they are your best available sustainable choices.

Much of the high street is now using ECONYL and REPREVE for the majority its swimwear, including sports brands such as Speedo and Sweaty Betty. We’ve also included some smaller brands that are more ethically focused than the high street giants – ensuring that production, packaging and fair pay are at the centre of their core values.
