PROTECTION SCIENCE

Engineered
light.

A sunscreen number is a lab figure on still skin. Protection is what survives an hour of sweat, glare and friction. Everything we make is designed for the second number — the one still on your skin when the session ends.

FOUR THINGS THAT MATTER

How it protects

01

Broad Spectrum

Modern UVA + UVB filters tuned to hold their absorbance under heat and light, not just at the moment of application. The whole spectrum, not only the part that reddens skin.

UVA + UVB · PA++++
02

Sweat-Proof Film

A film engineered to key into skin and survive friction. In an 80-minute sweat protocol Solar Spray keeps 96% of its SPF, where a standard lotion sheds more than half.

03

Invisible Micro-Mist

A 55-micron particle lands even and disappears — no white cast, no greasy grip over a strap. Pressure-free, and it fires at any angle, even upside down.

Reef-Safe Filters

No oxybenzone, no octinoxate. Non-nano, fragrance-free, and formulated to be kind to the water you train in as well as the skin you train on.

0 OXYBENZONE
THE 80-MINUTE TEST

Holds where lotion slides.

Very water-resistant sunscreen is tested across 80 minutes of immersion, then re-read. It’s the closest standard to a hard hour of sweat. Our micro-mist keys into skin instead of sitting on top of it — so far more of it is still there at the end.

KNOW THE INDEX

Read the UV

The UV index tells you how fast unprotected skin burns. Altitude, snow and open water push it higher than the air temperature ever suggests.

APPLICATION

Smaller lands softer.

A typical aerosol throws coarse droplets that bead, drip and leave a film you can feel. Our pressure-free pump atomises to 55 microns — a fraction of the size — so it lands even and invisible, with no white cast over a strap and no greasy grip.

THE FILTERS

What blocks the light

Modern broad-spectrum filters, chosen to hold their absorbance under heat and light — and to be kind to the water you train in. No oxybenzone, no octinoxate, non-nano.
