Can We Make 100% Plastic-Free Clothing? with Meli and Rensso Hinostroza of Eco Aya and Arms of Andes
How Fitting: design a slow fashion business that fitsShow Notes
If you are anything like me, you’ve started paying way more attention to the ingredients in our food and realized just how many nasty ingredients are hidden within. If comprehensive ingredient labels existed for clothing, they would be equally shocking. Even in garments labeled as “natural fibers”, there are hidden sources of plastic and chemicals that have a negative effect on our health and the health of our planet.
For Meli and Rensso Hinostroza, this realization turned into curiosity and a deep dive into 100% plastic-free clothing production. The two siblings have started two brands – Arms of Andes and Eco Aya. In episode 133, we go into the nitty gritty details of eliminating all plastic from the clothing they make down to every thread, zipper, button, and fabric finishing and how they had to set up their manufacturing to do it.
Melissa and Rensso Hinostroza are the sibling co-founders of Eco Aya, a plastic-free non-toxic lifestyle brand, and Arms of Andes, home of the world’s only 100% alpaca outdoor apparel. In an industry dominated by synthetic fibers and microplastics, the sibling duo have returned to their roots to offer a high-performance alternative that is entirely natural and biodegradable.
Born in California and raised between the U.S. and Peru, they have spent their lives navigating two worlds, a perspective that allowed them to see how heritage-driven techniques could solve the modern environmental crisis in the global outdoor market.
Meli Hinostroza is the brand’s creative force and strategic visionary. She leads marketing, sales, and the customer experience, ensuring that every campaign reflects their deep-rooted commitment to the planet. For Meli, the mission is to dismantle the industry's reliance on plastics by building a brand that connects people back to nature through sustainable, purposeful design.
Rensso Hinostroza is the operational backbone of the company. With a background in international business, he manages the entire supply chain directly from Peru. He is the guardian of the brand’s transparency, overseeing everything from sourcing raw fibers to final production. A believer in a minimalist approach to adventure, Rensso is dedicated to proving that performance gear doesn't need chemicals or plastics to excel in the world's harshest environments.
Together, Meli and Rensso are bridging the gap between ancestral wisdom and modern technical performance, proving that the future of the outdoors isn't synthetic, it's natural.

If we’re talking about how values show up in the creation of specific clothing styles, you won’t find a better example of this than fair trade fashion. For fair trade fashion brands, the process is just as important as the product. Collections don’t begin with design inspiration, they stem from family-owned production partners, long-term boutique relationships, cross-cultural collaborations, and a commitment to each person involved.
A good product is not enough. As much as we’d like to pour our creative time and resources into creating the most beautiful design and exquisitely crafted product and then let it sell itself, it just doesn’t. In fashion business, the job doesn’t stop when the garment is produced. Marketing it is just as important. And that job actually starts before the product even exists.
If you run a slow fashion brand, you’ve probably experienced this. You saw how wasteful the fashion industry can be and vowed to run your brand differently. You want to pursue quality over quantity, sustainable materials and practices, fair labor, and avoid over-production. But how does this slow fashion intent meet the reality of factory MOQs, wash tests, and production costs for a new brand? Plus, as the brand grows, is there a scale where a slow fashion brand is no longer slow fashion?
As entrepreneurs, we didn’t start businesses to create a job that we hate. In fact, for most of us, it is quite the opposite. We want our work to be fulfilling. But we also want it to pay the bills and not burn us out. So how do we build a business that is both fun and financially stable? That offers both creative confidence and commercial control? Where the day-to-day process feels magical, but also manageable?
We’re told in fashion business that your brand’s patterns are your IP, don’t let anyone else have access to them. It is true that your patterns are one of the most legally protectable aspects of your brand’s unique fit and design aesthetic, but is gatekeeping patterns really necessary for fashion business success?
