The Arctic 10+ in Arctic field conditions — built for the days between abandonment and rescue, not just the first hour. Every immersion suit on the market is judged against the same question: does it meet the applicable standard? That's the wrong starting question, and it always has been. The right one is simpler and harder to hide from: if the person wearing this suit actually ends up in the water, or on the ice, does it keep them alive and functional long enough to be found

When a vessel receives its Polar Ship Certificate, a Recognized Organization certifies that it is fit for polar operations. In most cases, that certification is silent on whether the immersion suits aboard provide thermal protection adequate for the Maximum Expected Time of Rescue. That silence is the question this post is about.
