Sula-Mae Loewenthal is a no-gi grappling competitor who trains out of Gracie Barra London, one of the most established BJJ academies in the United Kingdom. Competing primarily in the featherweight (66kg) division, she has built a strong reputation as one of the more prominent grapplers on the European circuit at that weight.

In 2024, Loewenthal earned ADCC veteran status by winning the ADCC Asia and Oceania Trials — a result that secured her place among the elite at the world's most prestigious submission wrestling event. The trials victory marked a defining moment in her competitive trajectory, demonstrating her composure under pressure against a deep regional field.

Her growing profile in the no-gi community was further reflected in her feature on JitsCast episode #50, where she was highlighted as a standout featherweight competitor ahead of a high-profile title opportunity.

On November 1st, 2025, Loewenthal challenged Helena Crevar for the Polaris 66kg featherweight title at Polaris 34 — one of the most significant bouts of her career to date. The championship setting placed her at the forefront of professional no-gi competition on a major European stage.

Crevar retained the title by submitting Loewenthal with an arm-triangle choke. The finish highlighted Crevar's ability to capitalize on positional control and apply suffocating upper-body pressure, turning a dominant top position into a fight-ending submission. Despite the defeat, the title shot affirmed Loewenthal's standing as a legitimate featherweight contender and provided invaluable high-stakes experience against one of the division's most decorated champions.
