I learned the hard way that a snorkel can turn against you. A few years back, I grabbed my gear for a quick trip to the beach after it had been sitting in my car trunk for two months. The purge valve felt stiff. The silicone seemed tacky. I told myself it was fine and went in anyway. Twenty minutes later, I was gasping on the surface, my heart pounding, trying to figure out why breathing felt so hard. I wasn't panicked-I was struggling. That day, I got lucky. But it made me dig into something I'd never considered: how we store our gear could be quietly making it harder to breathe.
That experience sent me down a rabbit hole of research, including the Snorkel Safety Study from Hawai'i. That study found that nearly half of snorkel-related drownings were linked to a condition called SI-ROPE-Snorkel-Induced Rapid Onset Pulmonary Edema. One of the key triggers? Inspiratory resistance. The harder your snorkel is to breathe through, the more negative pressure your lungs have to generate. Over time, that strain can lead to fluid buildup in the lungs, shortness of breath, and loss of consciousness.
Here's the part that surprised me: resistance isn't just about design. It's about wear. And wear often comes from storage.
What Happens to Gear When You Stash It Wrong
Think about what your mask and snorkel go through between trips. Tossed in a bag. Left in a hot car. Squished under towels. Exposed to sunlight through a window. These aren't just cosmetic issues-they change the material properties of your gear at a microscopic level.
- UV light degrades silicone and polycarbonate, creating micro-cracks and surface roughness that increase airflow resistance.
- Heat can soften and permanently deform purge valves, causing them to lose their seal.
- Compression-from stacking gear or cramming it into a tight bag-can leave silicone skirts with a "memory" that prevents them from sealing properly.
- Salt residue left to dry inside the snorkel bore creates abrasion and changes how water sheets off surfaces, making clearing harder.
None of this is obvious to the eye. The study found that even experienced technicians could only identify high-resistance snorkels by inspection 26% of the time. If the pros can't see it, how would you know your gear has changed?
The Link Between Storage and Safety
The Snorkel Safety Study measured resistance in dozens of snorkel devices and found that some required over -5 cmH₂O of negative pressure to inhale at normal flow rates. That might not sound like much, but multiply it across every breath for ten minutes, and your lungs are working overtime. The study's survivor accounts consistently mention "extraordinary effort" as a precursor to trouble-swimming against currents, long distances, or simply trying to breathe against resistance.
Now imagine your gear has added resistance from poor storage. You're already exerting yourself. Your snorkel should be helping, not hindering. When a purge valve doesn't seal because it was stored compressed, water seeps in. You blow harder to clear it. Your breathing rate increases. The negative pressure in your chest climbs. It's a cascade that can escalate fast.
The study documented this sequence in real cases: sudden shortness of breath, fatigue, loss of strength, a feeling of doom, then diminishing consciousness. It happens quickly and quietly. "Not all drowning looks the same," the study warns. "Few, if any, signs of distress."
What I Changed About My Gear Care
After learning this, I completely revamped how I handle my Seaview 180 mask and snorkel. Here's what I do now:
- Rinse with fresh water immediately after every session. Salt crystals are abrasive and change surface properties. A quick rinse prevents long-term damage.
- Dry thoroughly before storing. I hang my gear in a shaded, ventilated spot. Moisture trapped inside a zipped bag is a breeding ground for mold and material degradation.
- Store in a cool, dark place. My mask and snorkel live in a drawer, not a car or garage. UV light is the number one enemy of silicone and polycarbonate.
- Avoid compression. I keep the mask in its case, and I make sure nothing presses on the purge valve or the skirt. A deformed seal won't seal.
- Do a pre-trip check. Before I leave home, I run my finger inside the snorkel bore-does it feel smooth? I press the purge valve-does it snap back instantly? I check the skirt-is it supple, not sticky or brittle?
These steps take three minutes. They've kept my gear performing like new for years.
Why This Matters More Than You Think
The Snorkel Safety Study's final report states plainly: "Responsibility for safety lies with the snorkeler." It's not the ocean's fault. It's not the gear designer's fault. It's on us to make sure our equipment is ready.
Your Seaview 180 mask is engineered with features designed to support comfortable breathing at the surface. Its airflow separation is intended to reduce CO₂ buildup. But those features rely on materials staying true to their original shape and surface chemistry. If you store it poorly, you're undermining the engineering that keeps you safe.
I'm not here to scare you. I'm here to share what I wish someone had told me years ago: how you store your gear matters for more than just longevity. It matters for your breathing. It matters for your safety.
Next time you come back from the water, take those few extra minutes. Rinse. Dry. Store carefully. Check before you go out. The ocean will always be unpredictable. Your gear doesn't have to be.
See you in the water.
