Yes, perhaps they could do more with the website than what they have.

Yes, it is as waterproof as a plastic tarp. I've seen it demoed where it is hung by the corners and a gallon of water is poured into the middle and absolutely no water penetrates to the bottom all day long. In my own experience, the only time the inside got wet was due to me perspiring on it or me letting water come in around the edge. Even then, the fabric did not soak (well it did just a bit where I had the blanket compressed up under my arms and my pits sweated into the fabric under tight contact, but I would say moist, not soaked).

You cannot push a blunt tip through it using body strength/weight. You cannot rip it with your bare hands. You can cut a hole in it with a knife, but if you snag on barbed wire, it won't tear, but the puncture may stretch a tad. Laying on top of it on top of a bed of gravel, it showed no signs of abrasion. I could damage a army surplus wool blanket easier than I could my artillery blanket using the same effort.

I am 6'5" tall and weigh 265-270. The artillery blanket is big enough to wrap around me 1 1/2 times from just past my toes to over my shoulders and up to my chin. I've thrown it around me and the wife more than once, and while it won't wrap us quite as snug as by myself, I can get the sides to touch around us. Draped over us in bed, it is wide enough to cover us both if we snuggle.

I've had it as a shooting pad in the prone position at the range for an all day shoot, which meant laying on it, squirming around, standing and walking on it, having cases and guns and gear strewn upon it. It will melt if the brass gets too hot to handle or you spill solvent or some such on it, so I exercised a modicum of care in that regard, but when I took it home and washed it, it looked as good as new. I've washed one of the blankets at least a hundred times in a washing machine that likes to eat terry cloth towels, and no problems, it will not delaminate under any condition I've exposed it to as yet.

Surprisingly, it is not as thick as you would think. It feels denser than the typical fleece material, because the laminate adds a bit to the resilience. It behaves more like supple leather in that regard, and wearing clothing made out of it is like wearing supple leather as well, except that it has a knap that you can feel. It absolutely will not pil, or get those little balls on it. If you were to run your hand over it, you might think it feels almost like mohair, almost. It is somewhere in between standard fleece and monkey hair, in that the knap is not as crushable as monkey hair is, and it shows more of a woven style than monkey hair, but does have a bias to it of sorts. Comfort wise I put it right up there with Polartec 300.

Back when I was first trying to decide on whether to make such an investment (I was a skeptic as well), I asked for a sample of the material. They sent me a swatch, and it didn't take me long afterwards to make my decision. Maybe if you contact them they will send you a sample as well.

Yes, it is spendy. You do get a one year damage warranty, which seems fairly substantial for something made out of fleece material. I've owned products from them for 5 years now, and none of it has failed or been damaged in any way, even the wear I've put on them is nearly unnoticable.

If you don't want to throw down too much up front, get one of their discontinued bucket hats for $10. For that price, if you don't like what you get, I'll buy it off you.
