NEW YORK – October 31, 2026 -- Wulcea's graphene-powered heated apparel comes with a UL-certified battery system, heating elements tested through 10,000 flex cycles and 100 machine washes, and sensors that stop heating above 131°F (55°C).
The brand is putting safety documentation front and center as smart heated clothing gains wider adoption. "Trust in smart heated apparel goes beyond warmth," said founder John C, who tied the company's goal to giving users peace of mind through certified technical standards.
Flexible graphene elements keep the garment soft
Wulcea's GrapheneNano heating technology uses flexible graphene elements to deliver balanced warmth across key upper-body zones. The design aims to avoid garment stiffness, so the clothing keeps its natural drape and allows full freedom of movement.
The heating components come with compliance documentation for major markets. CE and FCC documentation covers electrical and electromagnetic compatibility, and PSE compliance applies to relevant products in Japan. RoHS compliance addresses restrictions on specified hazardous substances in applicable electrical and electronic components.
The rechargeable battery carries UL certification and UN 38.3 testing
The batteries are compact and sit in dedicated interior pockets, keeping the garment profile streamlined. UL certification shows the battery system was evaluated against recognized power bank safety requirements, including overcharge protection, short-circuit protection and thermal safety.
The batteries also come with applicable CE and FCC documentation and RoHS compliance for material safety. The battery models have undergone applicable UN 38.3 testing, which supports compliance with international requirements for transporting lithium batteries, a relevant point for travel.
Heating elements survive 10,000 flexes and 100 washes
Wulcea tests its flexible graphene heating elements through 10,000 active flexing cycles to maintain steady thermal output through repeated bending and everyday movement. Under standard care guidelines, the elements withstand 100 machine-wash cycles while maintaining internal conductivity and structural stability.
Integrated NTC temperature sensors monitor heat and are designed to stop heating if temperatures exceed 131°F (55°C). The low setting runs for up to 10 hours, and a discreet interior control button operates the garment.
