Update. Sorry to say blanket number two also failed miserably. We had significant rain in the Northeast today I put it on the horse last night and the whole thing is wet underneath . The kicker being my farm owner has several of the same blanket she purchased a few years ago and her horses are bone dry.
So back it goes and I ordered a Rambo from my favorite NJ tack shop.
————————
I decided to try it because of the 10 year guarantee. First day out in the rain and it got soaked through all the way head to tail. This is a blanket with an attached neck. I am normally a diehard Rambo Fan. Anyone have a good luck with SmartPak turn out? Mine is going back.
