Other Wearables Notice. Sōl Is Designed to Respond.
Many wearables can tell you you’re stressed. Then it’s up to you. Serene by Sōl™ is a titanium and natural bamboo bracelet designed to read three signals (heart rate variability, skin response, and motion) and release a soft, personal mist of essential oil when your body shows signs of stress.

Know the Difference Between a Workout and a Hard Moment
Traditional Wearables (Heart Rate Only)
A racing heart can mean you’re crushing a workout or bracing for a difficult conversation. Heart rate alone can’t always tell the difference, so Serene by Sōl is designed to read three signals together:
• Heart rate variability: subtle changes in the rhythm between heartbeats
• Skin response: tiny shifts in skin conductance linked to your body’s stress response
• Motion: whether you’re moving or sitting still
When your body shows signs of stress while you’re still, Sōl is designed to respond. When you’re clearly working out, it’s designed to stay quiet.

Forged in Strength. Rooted in Nature.
Titanium Exterior (The Shield)
The outer shell is designed in titanium, a metal chosen because it’s strong, lightweight, and naturally resistant to corrosion. A quiet reflection of the strength you carry within.
Organic Bamboo Interior (The Soul)
The inner lining is natural bamboo, designed to be sealed against everyday moisture. No two stalks share the same grain, so no two bracelets will look exactly alike. A lining that’s yours alone.
Sense. Understand. Respond.

Respond
Sensors set into the bamboo lining are designed to read your heart rhythm and skin response quietly throughout the day.
Sōl is designed to read those signals together with motion, so a hard workout isn’t mistaken for a hard moment.
When the signs point to stress, a small atomizer is designed to release a soft, personal mist from your scent cartridge. Automatic by design. Nothing to remember.
