3RD ROCK Founder & Designer Jessica Mor

Words by Matt of ReddyYeti

There’s no question that 3RD ROCK’s apparel and activewear is awesome but, beyond the surface of their products is where the magic really happens. What started as a way to make better, more comfortable, and eco-friendly apparel quickly grew into something a little more. It’s easy to label yourself as a do-good company by donating some funds to an organization and calling it a day; however, 3RD Rock goes above and beyond to create sustainable products while doing what they can to make the climbing space much more inclusive.

In this episode of Built On Passion Jessica Mor shares how she jumped from the fashion world to the climbing industry, her approach for developing functional garments and sustainability, opening up climbing for as many people as possible, and the “How” and “Why” behind 3RD ROCK.
