Why your current SPF fails on a long day out.
Most sun protection was designed for the beach. Not for five hours of moving, sweating, scrambling. Everything changes when you're actually working hard on the hill.
It's gone by hour two.
Your kit is cooking you.
Treated UPF washes out.
Why hill walkers choose LifeJacket.
- UPF 50+ woven in. Blocks 98% of UV, summit to summit.
- Moisture-wicking fabric keeps you cool on the climb.
- Protection that doesn't wash out after 20 miles or 20 washes.

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.
