Our Materials

What we wear matters

Hass uses the most sustainable materials on the planet. By harnessing natural, organic, and innovative fabrics, we reduce our impact on our environment — less water use, fewer carbon emissions. And our organic labels verify less pesticide use, which is better for everyone who comes into contact with our fabrics, from our farmers, to our factory team, to you. Plus, natural materials are more luxurious. They feel better. They last longer. They look great.

Organic Cotton

Safe, Sustainable, Ethical

Conventional cotton is one of the dirtiest crops on the planet, heavily reliant on pesticides and excessive water use. It has an enormous carbon footprint. The toxic chemicals used to grow it are linked to higher rates of cancer, asthma, and birth defects where the crop is grown.

Farmers grow GOTS certified organic cotton without pesticides. It has about half the carbon footprint of conventional cotton. It uses around 70 percent less water. Our GOTS certification (CU863637) from India also validates fair and ethical treatment for farmers, which results in safer, more sustainable communities.

Alpaca Fiber

Renewable AND Deluxe

Possibly the greatest, most sustainable fiber on Earth, Alpaca wool was once reserved for Incan royalty. It’s still sought after for its unparalleled warmth, luxurious texture, light weight, and temperature and moisture regulation. It’s also naturally renewable with a small carbon footprint. We source our alpaca collection ethically from the Peruvian Andes.

Modal

Luxurious and Durable

Made from beech tree pulp, Modal is a soft material originally developed in Japan. Lenzing-certified modal, which we source from Austria, is the textile industry standard that verifies ethical and sustainable material sourcing and manufacturing. The cellulose-based textile is more durable than rayon and has a silkier quality than cotton. It’s also a more environmentally friendly alternative — beech trees require little water to thrive and the production process consumes 10 to 20 percent less water than cotton.
