Mammoth is based in Seattle, Washington—a place where mountains, forests, and coastlines shape how we see the world. Our love for the outdoors and its natural beauty inspires everything we make. We focus on quality craftsmanship and carefully chosen fabrics, working with small-batch manufacturers in Canada, Italy, and China who share our dedication to detail. Sustainability guides us at every step: we commit to ethical wages, eco-conscious packaging, and creating products built to last. For us, clothing is a reflection of care for people, craft, and the planet.
