In addition to wearing this product by itself, it makes a great adder to a wet suit when diving in colder water.
The vest is fine. it has held up very well. I actually bought it to wear while working out/running. I should have bought a long though instead of a regular. It does seem to have shrunk some in the lenght, just doesnt seem to be as long as when I got it. At some time in the future I will purchase another in a long lenght.
