This raincoat is of an amazingly high quality - second to none. I've owned several sets over the years, both civilian sets and military sets, and this one is by far the most rugged and waterproof set ever. It's heavy duty thick PVC that repels even the worst downpour - it will seriously keep you dry.

It is however non-breathable, so make sure and wear something appropriate underneath, as it'll get rather warm, just from your own body heat. I always layer my outdoor clothing, so I can easily adjust to any temperature. It is a heavy raincoat; none of that flimsy nylon "water repellant" stuff here.

As far as sizing goes, it is definitely well over-sized. I usually wear a 2X-Tall (sometimes a 3X-Tall), and I found that a 2X-Tall is more than sufficient for me, also allowing for plenty of layers of clothes underneath.

I would highly recommend it to anyone needing a serious raincoat, however, for your everyday "go shopping"-raincoat, this is a little overkill.
