A new UK-based equestrian brand, Mulmet, is gaining attention with the launch of a lightweight horse riding helmet designed to support comfort during longer periods in the saddle. Founded in 2025 by Sara Li, the brand draws on more than 15 years of helmet manufacturing experience to introduce a new approach to rider-focused design.
Mulmet’s debut helmet weighs just 450g, making it significantly lighter than many traditional riding helmets, while meeting ASTM F1163-23 and CE EN1384:2023 safety standards. Crucially, the helmet is approved by the British Horse Society (BHS), British Showjumping and British Dressage, meaning it meets the requirements for competitive riding in the UK.
Lightweight Riding Helmet Designed for Comfort and Performance
Comfort remains an important factor for riders, particularly during training sessions, competitions and long days in the saddle. Mulmet’s design reduces overall helmet weight, improves airflow to support rider concentration and addresses the very real issue of headaches and discomfort over long rides.
Early feedback from professional riders and trainers has been positive, particularly in relation to fit and comfort. Riders have reported that the lightweight feel allows them to maintain focus without distraction.
Advanced Helmet Technology with Certified Safety Standards
Mulmet’s riding helmet incorporates two proprietary technologies developed over more than 15 years of manufacturing and research.
Multi-density EPS foaming uses engineered expanded polystyrene to deliver effective impact absorption while reducing weight. This allows the helmet to weigh around 450g compared to approximately 1,000 to 1,500g for many comparable helmets on the market.
Angle-moulded ventilation introduces seven ventilation channels using angled geometry and hidden reinforcement. This design improves airflow while maintaining the structural integrity required for safety certification.
Direct-to-Consumer
Mulmet has adopted a direct-to-consumer model, selling its horse riding helmets through equestrian events and its own online platform rather than traditional retail channels. You won’t find the helmets in stores, filtering out noise to help customers make an educated, rather than over-saturated decision.
In 2025, the brand launched at major UK horse trials including, Badminton, Burghley, Your Horse Live and the London International Horse Show. Riders visiting the stand frequently commented on the helmet’s lightweight feel, with many choosing to purchase after trying in person.
Mulmet to Showcase Helmets at Major UK Horse Shows in 2026
Mulmet is set to attend more than 20 horse shows across the UK in 2026, including the Mars Badminton Horse Trials. Founder Sara Li will be present to answer any questions and again, offer riders the ability to try the helmets firsthand.
The brand is also launching a rider sponsorship initiative through the Mulmet Riders Team, supporting both amateur and competitive riders across the UK equestrian community.
A Highly Skilled Founder
Sara Li brings over 15 years of experience in equestrian helmet manufacturing. She co-owned and directed a helmet manufacturing company in Taiwan from 2009 to 2025, helping grow it into a globally recognised supplier and contributing to three Taiwan National Excellence Awards.
She holds an MBA from Warwick Business School and an MSc in Entrepreneurship from UCL. Mulmet reflects her combined experience in manufacturing, innovation and business strategy, with both core helmet technologies developed under her leadership from concept through to certification.
