get the most comfortable, coolest looking one you can! Just like purchasing a leather jacket or a cool shirt. that way you'll want to wear it!

some interesting facts....

Q: How often should a PFD be tested?

A: At least once a year for wear and buoyancy. If waterlogged, faded or leaky, a PFD should be discarded properly so someone else does not use a retired model.

Q: How long does a PFD last?

A: There is no standard time limit, though proper care will make it last longer. Waterlogged materials, mildew odor or buoyancy shrinkage indicate the need for replacement.

I thought a faded, mildew-ey pfd was a badge of honor.  I'm sure rei would love for us to buy a new one every season.
