At SEPTEMBER the line, we are passionate about giving back to the mama who sends us the waves: mother earth. Sustainability does not have to be a luxury. It needs to be an affordable option for everyone.

From the materials, trims, and packaging—including our plastic-free hygiene liners, our classic shapes are made even better because of our passion for sustainability in fashion and beyond.

The Perfect Fit | Italian Recycled Fabric

When we use recycled fabric, we’re not only focusing on the perfect fit for you, but the perfect fit for the future of our planet.

Our signature luxury Italian recycled fabric is made from 78% ECONYL® regenerated nylon and 22% elastane made from pre and post industrial waste such as ghost fishing nets and carpet fluff.   Instead of being disposed of in the landfill, they are recovered and transformed into the regenerated nylon that makes your SEPTEMBER the Line swimsuit.

Our innovative construction makes it twice as resistant to chlorine and suntan creams and oils than conventional recycled fabric. Plus, it’s also a UV protection of 50.

Durability = Sustainability

Our classic shapes and construction are inspired and designed by surfers. Why is this important? As a surfer, you have an inherent connection with the salt water that provides the peace and quiet that gives you piece of mind between sets; we call this water healing.


 Durability is essential to swimwear that works. That’s why our recycled nylon is woven with 22% Xtra Life Lycra®, a higher durability than mainstream swimwear fabric.

Many brands use a thinner and cheaper lining material on their swimsuits. We don’t do that. We line all our swimsuits and bikinis with the same amazing Italian recycled nylon as the outer fabric. This gives the suit an enhanced shape retention that sculpts the silhouette, smooths and supports you in all the right areas, and leaves you feeling amazing and confident in and out of the water.
