BAND

Every hour has a cost. BAND is how you start to see it.

LIVE CARBON SIGNAL — WORN, NOT CHECKED

Your wrist already knows the cost.

BAND is a wristband that reads your real-time carbon footprint and glows to show it — green when you're light, blue when it's building, red when it's not. No app to open. No number to check. Just a color you already understand.

Early access opens in limited batches. No spam, one email when your batch is ready.

You're on the list. We'll be in touch.

Three colors. One glance. Nothing to interpret.

BAND doesn't hand you a dashboard. It converts your footprint into a signal your eye already reads faster than a number — the same way traffic lights outran instruction manuals.

From wrist to signal in three steps.

01

Wear it

A soft, closed-loop band, waterproof and built to stay on through your day, not just your workout.

02

It syncs

BAND pairs with your phone and pulls in location, transit, and activity to model your footprint hour by hour.

03

It glows

The band itself shifts color in real time — green, blue, red — so the feedback lives on your body, not in a notification.

We track sleep. We track steps. We track heart rate. It's time we tracked the thing we're actually running out of.

Be the first to wear one.
