Choosing the right lifejacket isn’t just a matter of compliance — it’s a matter of life and death. And when you’re outfitting a professional crew, equipping a charter fleet, or preparing a commercial vessel for EU inspection, knowing the difference between ISO-certified and SOLAS-certified lifejackets is key.
This article breaks down the essential differences and helps you make a practical, informed choice — whether you’re running day trips in the Med or prepping for offshore operations.
What’s the Difference Between ISO and SOLAS Lifejackets?
ISO lifejackets are certified to the ISO 12402 standard. They’re widely used in recreational boating, training fleets, and smaller commercial craft. These jackets:
Provide 100N to 150N of buoyancy
Are generally lighter and more compact
Require manual or automatic inflation, depending on the model
Are suitable for coastal and inland waters
SOLAS lifejackets, by contrast, comply with the International Convention for the Safety of Life at Sea (SOLAS) — the highest global standard. These jackets:
Delier at least 275N of buoyancy
Feature high-visibility colors, reflective tape, and whistle
Are designed to turn an unconscious person face-up
Include additional fire-resistant and durability standards
Are mandatory on many commercial vessels, ferries, and offshore ships
Bottom line?
ISO lifejackets are great for comfort and mobility, but SOLAS-certified options are built for the harshest conditions and emergencies.

Still unsure? Here are key questions to guide your decision:
What kind of water are you operating in?
Coastal? Inland? Offshore?
Who will wear the jacket?
Trained crew or guests unfamiliar with marine safety?
What conditions are likely?
Cold weather, high seas, commercial pressure?
Do you need SOLAS compliance for your inspections or flag authority?
