Do you sit on your pfd during shore breaks? Think again...foam breaks down over time and sitting on it acceelerates this. That means you won't float as well in the water, and you're more likely to submerge in waves or turbulence. When a pfd is starting to show signs of UV degredation and other wear and tear, it has most likely lost several pounds of it's standard 7-8kg (16-18lbs) of flotation. The label has a specially designed ink that fades at a specific rate. If it's significantly faded, the foam is significantly degraded!
