Sunscreen, clothing, and eyewear all do different jobs — and none of them work well alone. This section covers each layer of protection on its own terms: what the labels actually mean, what the evidence says, and how to choose gear that matches what you’re actually doing outdoors.
Sunscreen
- How to Choose Sunscreen for Outdoor Sport — SPF, broad-spectrum, water resistance, and reapplication, explained for hikers, cyclists, golfers, and anglers.
- SPF 30 vs SPF 50 — the difference is smaller than you think, and the number isn’t the factor that matters most.
- SPF Alone Isn’t Enough — why broad-spectrum protection matters more than the number on the bottle.
- Sunscreen Doesn’t Last All Day — when to reapply, and why “water-resistant” isn’t “all-day.”
Clothing
- UPF Clothing Explained — what UPF 50+ actually means, and how to choose the right garments for your activity.
Eyewear
- UV Sunglasses Explained — UV400, polarized lenses, and how to choose sunglasses that actually protect your eyes.
