I will be the naysayer on this rainsuit. For sure I don’t like it as a rain outfit for trout fishing. Even though it breathes it is hot, and not much relief as the sleeves are elastic. I tore the pants the very first time out on a piece of barb wire. I don’t even carry them in the boat. I use a regular rainsuit that cost about a hundred bucks. I would put another 20 to 30 bucks together and get your son a real rain suit.
Just my two cents worth.
