Why sunscreen isn't enough when you're moving.
Sunscreen was designed for the beach. Not for two hours on a clifftop trail in July heat. The moment you start sweating properly, the protection changes. Not in your favour.
Sweat takes it with it.
You're not stopping to reapply.
Treated UPF washes out.
Built for the hours you spend outside.
- UPF 50+ woven in. Blocks 98% of UV rays, wash after wash.
- Moisture-wicking fabric moves sweat away so you stay cool and comfortable.
- Protection that lasts. Not chemically treated. It won't wash out after 20 sessions.

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.
