Introduction
If you love the outdoors but worry about UV damage (or what your sunscreen might be doing to the environment), you're not alone. I was just planning my next snorkelling trip when I began contemplating what sun protection I should be using, and like many people others, I am looking for ways to stay sun-safe while minimising my impact on the planet.
This guide dives into practical tips for eco-friendly sun protection, including reef-safe sunscreen, UPF 50+ clothing, and timing your sun exposure wisely. As a brand committed to sustainable living and skin safety, equatorsun brings you this complete guide to enjoying the sun responsibly.
Let’s explore how you can stay protected without compromising comfort or the coral reefs.
The Problem with Traditional Sunscreen

UV Risks vs. Sunscreen Drawbacks
Sun protection is essential — there’s no getting around that. Prolonged UV exposure is directly linked to premature aging, sunburn, and more seriously, skin cancer. But while sunscreen has long been the default solution, it’s not a perfect fit for everyone.
We regularly hear from customers who struggle with sunscreen: some experience stinging, rashes, or allergic reactions, especially those with sensitive skin. Others simply dislike the greasy or sticky feeling, particularly in hot or humid conditions. And then there are the environmental concerns — certain chemical ingredients commonly found in sunscreens, like oxybenzone and octinoxate, have been shown to contribute to coral bleaching and marine ecosystem disruption. That’s why destinations like Hawaii and Palau have taken action by banning these substances outright.
Even sunscreens marketed as “reef-safe” can be misleading due to inconsistent industry standards. Without clear regulation, it’s hard to know which products are genuinely safe for the ocean and which are just cleverly marketed. For those who want to protect both their skin and the environment, this creates an overwhelming — and often frustrating — dilemma.
Concerns We Hear
In our work with travellers, divers, surfers, and everyday sun-lovers, we’ve noticed some recurring questions:
- “Is sunscreen the only way to stay protected?”
- “If I wear a UPF shirt or rash guard, do I still need sunscreen?”
- “What can I do to protect myself without harming coral reefs?”
These aren’t hypothetical. They come from real experiences and genuine concerns shared with our team. And we understand them — because we’ve had the same questions ourselves. The good news is that there are better, more sustainable ways to stay sun-safe. The first step? Rethinking sunscreen as the only line of defence.
UPF 50+ Clothing: Your Sustainable Barrier
What is UPF Clothing?
UPF (Ultraviolet Protection Factor) clothing is specially designed to block harmful UV rays. A typical cotton t-shirt may only offer the equivalent of an SPF 5 sunscreen, while UPF 50+ garments block 98% of UV rays.
This makes UPF clothing a powerful alternative or complement to sunscreen, particularly for people with sensitive skin or those wanting to protect marine ecosystems.
How UPF Apparel Protects You
These garments use tight weaves, synthetic fibres, or built-in treatments to keep UV rays out. Unlike sunscreen, they don’t rub off, don’t need reapplication, and don’t sting your eyes or irritate your skin. Dermatologists often recommend UPF clothing as a consistent and hassle-free layer of defence. If you're not sure whether UPF/sun protective clothing works or if they are worth it - make sure to read our guide on sun protective clothing.
Many people are surprised to find that long sleeves and pants can actually feel cooler than bare skin. Technical fabrics used in sun hoodies and trail pants wick moisture, breathe well, and protect your skin from both sun and heat. Desert travellers and mountaineers have long known the secret: covering up can keep you cooler.
Environmental Benefits
Less sunscreen on your skin means less in the ocean. One high-quality UPF shirt can reduce the amount of sunscreen you need by up to 90%, helping protect coral reefs and marine life. Plus, fewer empty bottles means less plastic waste over time.
Common Concern – Will I Overheat?
It’s a valid concern, especially in warmer climates. But the truth is, modern sun protective clothing is specifically designed for hot conditions — it’s lightweight, breathable, and moisture-wicking. Many outdoor enthusiasts actually find they stay cooler when their skin is shielded from direct sunlight. For maximum comfort, opt for light colours, relaxed fits, and well-ventilated designs.
Planning to explore a reef? The water will help regulate your body temperature, and wearing a UPF 50+ rash shirt means you can protect both your skin and the ocean. A well-made rash guard — like those in our collection — looks great and performs like a regular top, so you're covered in and out of the water.
Is It Actually Practical?
Here’s How You Can Protect Both Your Skin and the Ocean
Meet Alex, an avid traveller who’s learned how to enjoy the sun without harming his skin or the planet. Here's how a typical day looks for him:
Morning – 8:00 AM Snorkelling: Alex wears a UPF 50+ swim shirt and swim leggings. He applies a bit of mineral sunscreen on his face and feet. With most of his body protected by clothing, he avoids a full-body sunscreen routine and the coral beneath stays safe.
Midday – 12:30 PM Lunch: Seeking shade under a palm tree, he switches to a lightweight linen shirt and relaxes. UV is strongest now, but Alex avoids it with timing and shelter.
Afternoon – 3:30 PM Hike: Back out on a coastal trail, Alex wears a breathable UPF hoodie, light pants, and a neck flap hat. He touches up his mineral SPF only on exposed areas. Hydrated and cool, he’s comfortable and safe.
Evening – 6:00 PM Relaxation: The sun’s rays are gentler. Alex enjoys the breeze in a t-shirt, confident in his eco-friendly routine. No sunburn, no guilt – just smart sun habits.
Conclusion: Enjoy the Sun – Responsibly
Eco-conscious sun safety isn’t just a trend – it’s a smart lifestyle. Whether you’re protecting coral reefs, your health, or simply looking for comfort outdoors, combining UPF clothing, reef-safe sunscreen, and good habits makes a powerful difference.

Frequently Asked Questions (FAQ)
Yes. UPF clothing covers most of your body, but areas like your face, hands, and neck still need protection. Apply mineral sunscreen to those exposed areas for complete coverage.
High-quality UPF clothing retains its protective qualities for dozens of washes. Garments made with UV-blocking fabric (not just a coating) can last for years when properly cared for.
UPF measures UV protection in fabrics; SPF measures how long sunscreen protects your skin from UVB rays. Both are important, but UPF provides consistent, non-chemical protection that doesn’t wear off.
Darker colors usually absorb more UV and provide better natural protection, but they can feel hotter. UPF-rated fabrics balance protection and comfort by using specially engineered light-colored fabrics that still block UV.
Yes. You can get vitamin D from short incidental sun exposure (like your hands and face), diet, or supplements. There’s no need to risk sunburn to maintain healthy vitamin D levels.
