Every collection has represented a key milestone in our transformation journey, and sustainability continues to influence the way we imagine, develop, and create our products.
The Product Sustainability Framework is our guiding document for creating products with reduced environmental impact characteristics.
Collection after collection, we go beyond the selection of lower-impact fabrics and extend the use of preferred materials to other components of our caps.
Atlantis Headwear’s goal is to convert more and more components to recycled alternatives. Since the ’24 collection, for example, our new visors have followed this direction. Through our collaboration with ReTraze®, we recover plastic bottles and fishing nets to create new materials for our products.
In the last 15 years, production in the fashion industry has doubled, while the average lifespan of garments has fallen by 36%: a figure that is simply unsustainable.
Durability is a feature we want to invest in more and more, together with constant attention to the technical and aesthetic performance of our products. To achieve this, our Quality and Compliance team studies the potential wear factors affecting our caps, so that we can take targeted action on the fabrics and manufacturing processes that need improvement.
We do not know who will wear it or keep it in their wardrobe, but we do know that our responsibility does not end with delivery.
That is why we are committed to providing all the information needed to care for our products, wash them properly and, at the end of their life cycle, donate, dispose of or recycle them responsibly, helping to extend their value over time.

How to measure
Measure the circumference of your head with a tape measure or use our size capture where the hat will rest (about 2.5 cm above the eyebrows).

Don’t worry, most of our hats are one size and adjustable with the closure on the back, so you can’t go wrong.
Check the headwear details to know if the style is adjustable or a double size.
If it actually is a double size hat, you can learn below how to measure your size.
