Sundial

Your body speaks to you through color

Smart fabric technology for swimwear and activewear that uses photodynamic dyes to create a personalized sun exposure sundial on your body. The fabric patterns visibly shift based on cumulative UV absorption—showing your real-time vitamin D balance versus skin cancer risk.

✨ The Wow Moment

You look down at your shoulder after hours of driving with your sunroof open or swimming at the beach and see the fabric has created an intricate mandala pattern—green spirals mean you're safely building vitamin D, but the moment red veins start creeping in, you know exactly which body part has hit its UV limit and needs to cover up NOW. No guesswork, no burning—just your body speaking to you through color.
