I live in South Florida and had concerns about the comfort of this PFD in the hot and humid climate. I have been extremely pleased. This PFD is so comfortable you forget your wearing it. The movement it allows is amazing. It has convenient pockets which are used for everything from keys to snacks. The clips for my knife are conveniently located in front and back. The adjustments you can make with this PFD make for the perfect fit. If someone else will be using it, the adjustments can be made quickly and easily. The quality of construction is visible and can be felt the moment you put it on. I am expecting years of use.
