Silky and Sustainable

Modal is a superior natural fiber. Ethically sourced from beech tree pulp, it’s 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. Plus, it’s manufactured using a closed-loop process, which repurposes 99% of the non-toxic solvent used during production and recycles expended water. 

Sewn In LA

More than 95 percent of clothing is imported from overseas. Often, the clothes are made in factories with devastating environmental impacts and terrible human rights violations, including forced child labor. Intensive carbon emissions from transporting garments overseas increase the greenhouse gasses that lead to the climate crisis. That’s why we cut, dye, and sew this leisurewear collection in Los Angeles with Lenzing certified modal from Austria. The Global Organic Textile Standard has thoroughly vetted our factory partners to ensure we’re meeting the highest standards of social and environmental responsibility.

Next-Level Comfort

Clothing With Integrity

At Hass, our elegant, luxury collections are made with natural, sustainable materials and never include harmful chemicals or synthetic fabrics. We’ve gone to great lengths to ensure the clothing we make doesn’t damage the planet, wildlife, our customers, or our workers. That’s how we’ll always do things.

A Force For Good

Hass is Climate Neutral Certified and a Certified B Corporation. We’re also members of 1% for the Planet and donate 1% of our annual revenue to environmental causes. And with every purchase, we donate a meal to someone in our community in need. It’s through these initiatives and our commitment to a clean supply chain that we believe Hass can be a vehicle for good, both locally and globally.


1% For The Planet

Created by Patagonia founder Yvon Chouinard, 1% for the Planet is a global organization that connects sustainably-minded businesses like Hass to environmental nonprofits. As members, we donate 1 percent of our annual revenues to verified organizations that address the interrelated issues of climate change, healthy food systems, land management, water resources, pollution, and wildlife diversity.

Certified B Corporation

Certified B Corporations are a new kind of business that balance purpose and profit — they legally commit to consider the impacts of their decisions on their workers, customers, suppliers, community, and the environment. It’s a community of leaders, driving a global movement of people using business as a force for good. Reed + Gwen, as a subsidiary of Avocado Green Brands, has a B Score of 126.2 points — well beyond the 80-point minimum threshold.

Climate Neutral Certified

The emissions from burning fossil fuels are the leading cause of our unprecedented climate crisis. Hass is proud to be Climate Neutral Certified for net zero emissions. We work with the nonprofit to voluntarily measure, reduce, and offset more than 100% of our scope 1, 2, and 3 emissions by supporting carbon offset initiatives through the Bonneville Environmental Foundation.
