Solo Stove, maker of smokeless fire pits, has officially registered its Signature Flame trademark, known for its clean burn.

Built on Solo Stove’s patented smokeless design and 360° Airflow system, which maximizes oxygen flow to create a bright secondary burn, the flame is now formally recognized as the Solo Stove Signature Flame.

To underscore the science behind its Signature Flame, Solo Stove partnered with Jennifer Walsh*, a Neurasthenics and brain-nature expert who serves as a global speaker and faculty advisor to Neuroscience departments at Harvard University and the University of Pennsylvania. Drawing on her knowledge of the brain’s connection to nature, Walsh explains that “staring at a flame for just 40 seconds may help people relax and reduce stress.”

“At Solo Stove, we’ve always believed our fire pits provide a unique experience that sparks family bonding, meaningful conversations and moments of calm in a world overwhelmed by technology,” said Liz Vanzura. “Jennifer Walsh’s research brings powerful validation to what our Solo community has felt for years and encourages ‘more green time and less screen time’ right in people’s backyards.”

Solo Stove identifies the following key features of its Signature Flame:

  • Iconic Flame Pattern – A distinctive “jet” design that sets Solo Stove apart and creates a focal point for outdoor gatherings.
  • Mesmerizing Vertical Vortex – A torch-like flame that captures attention and sparks conversation, while delivering the warmth and crackling sound of burning wood.
  • Engineered Control – Precision airflow channels direct the flame upward for a cleaner, safer burn.
  • Smokeless Performance – Secondary combustion eliminates smoke particles before they escape, to enjoy the fire, not the fumes or smell.
  • Warmth and Crackling Ambience – The heat and the natural crackle of burning wood enhance the sensory experience.

Solo Stove firepits all feature the company’s Signature Flame, including the Mesa, Ranger, Bonfire, Yukon, Canyon, and Summit 24.
