I'm back at the pool, ready to try out my life jackets, 2 different Helly Hansen's and 1 MarinePool. This time I will also be trying them out fully clothed, see if the extra weight of wet clothing makes a difference. I jump into the pool with each life jacket, floating around, and review each of them and reveal my favourite. *Please bear in mind this is filmed at a swimming pool using natural light and sounds*
