IMHO if you are looking at products at Dover, get the Northwind. It has a lifetime guarantee which means in 2 years when it’s so bitterly cold that the hardware snaps you can have it replaced with a brand new blanket.
I’ve had Bucas & Amigo and neither have held up well at all. I think the Bucas lasted less than a week.
I love Rambo, but they are expensive. We have a “second hand” Rambo that has been outfitted on nearly all of my TBs - it is at LEAST 10 years old and still going strong. It’s not as waterproof as it first was, but throw a rainsheet over it and you’re good to go - especially when it’s horribly windy. According to some posters on this forum Rambo lost its quality - I can’t attest, I’ve been happy with mine but it is ANCIENT.
But the best bang for your buck I think would be the Northwind turnouts, especially if you’re strapped to spend the big bucks and need something that lasts. My only gripe with the Northwinds is that the reflective strip that runs along their heavy-weights NEVER lasts after the first freeze - usually it cracks and splits once it gets cold… It doesn’t really bother me because it’s not a function of the blanket. My gelding’s Northwind is on its 3rd winter, and still looks brand new. So I’m happy with it so far.
