Your clothes are fixed. Your mood is not.
Change what your backpack says before school, a commute, a party, or a night ride.
Carbon NeuronPack
Say it without saying a word.
NeuronPack turns your backpack into a wearable display for your mood, message, identity—and the moments you want to connect.
Your backpack, your status
Most backpacks carry your things. NeuronPack carries your signal.
Online, you can change your avatar, status, meme, and mood in seconds. In real life, most self-expression is fixed, awkward, or hidden on a phone. NeuronPack brings that changing digital self into the street.
You do not always want to start the conversation.
Give people something to notice, understand, or respond to—without forcing the first conversation.
Your phone status stays online.
NeuronPack brings your changing digital self into the real world—on your terms.
