Why your current approach is leaving you exposed outside.
Most sun protection was designed for lying still on a beach. Not for hours of movement, sweat, and effort outside. Under real conditions, the usual approach breaks down fast.
It sweats off.
You're cooking in your kit.
Treated UPF washes out.
Built for people who stay outside longer.
- UPF 50+ woven in: blocks 98% of UV every single session.
- Moisture-wicking fabric keeps you cooler when it counts.
- Protection that never washes out, however many times you wear it.

HOW TO USE
Wear.
The UPF protection works immediately. No need to apply anything underneath unless you want extra face coverage.

HOW TO USE
Combine.
The tee covers your torso. Use Mineral Stick or Sun Gel for face, neck, and arms.

HOW TO USE
Pro Tip.
Throw this on before a run, hike or workout outside. It moves with you, breathes with you and keeps working however hard you push it. Physical protection that never taps out.
