Once I had mine adjusted it was a simple matter to slip it over my head like a t-shirt, keeping it all buckled together and if I'm really going to get wet (above the waist) I wear a wet suit and have pre-marked where I need to set the straps (larger) and then put it on like a coat by snapping the belt buckle together at my left side...yes it was a bit clumsy at first.
but after several hunts it has become an ease to put on and use.
I have only a short walk to the beaches I hunt so everything is kept in a lock box inside my Isuzu Trooper then put on when I make the short walk to the gold.
Side note: Mine came with the mounts and webbing facing the wrong way and if used that way the bolts would have been digging into my chest. It was easy to change it around and I also like that there was plenty of straps to fit my 5X size (I ordered the X-tra long model from Bill).
