Our Exercise Brand, OXB, is a female-founded jewelry line whose mission integrates fitness, design, and sustainability. Their jewelry is sweatproof; you’ll never have to take off your accessories again before stepping out for a run. Their pieces are made in-house by a production team of metalsmiths who use gold-filled, sterling silver, and 14k metals that won’t rub off, irritate your skin or end up in a landfill after a few wears.
