Swimwear is one of the most popular items of clothing worn during the summer months. Unfortunately, most swimsuits are made with synthetic materials that are not environmentally friendly. These materials often contain toxic chemicals which can harm marine life and sea beds when they end up in the ocean.

The good thing is that sustainable swimwear brands use eco-friendly materials and fair-trade practices. In this blog post, we will be discussing sustainable swimwear brands and the materials they use.

We will also differentiate sustainable swimwear from conventional swimwear and explain why sustainable swimwear is a better option for the environment.

So, without further ado, let’s get started!

Traditional Vs. Sustainable Swimwear: The Differences

Traditional swimwear is made with synthetic materials such as polyester, nylon, and Lycra. These materials are quick-drying, but they are not environmentally friendly. For instance, polyester is made from petroleum, a non-renewable resource.

Nylon is also derived from petroleum, and it takes centuries to break down in the environment. These materials are also not biodegradable and will sit in landfills for years.

Meanwhile, eco-friendly swimwear brands use recycled materials and fabric to make their swimsuits. One example is the ECONYL regenerated nylon, a type of recycled nylon made from fishing nets and other waste products.

This sustainable material can be recycled repeatedly without losing its quality. Recycled polyester is also used to make sustainable swimwear. This type of polyester is made from recycled plastic bottles and other post-consumer plastics.

Sustainable swimwear brands also use sustainable materials such as bamboo, organic cotton, and hemp. These materials are environmentally friendly because they are biodegradable and grown without the use of harmful chemicals.
