I have a Centaur and a Robin Hood.
The Centaur brand one is nice ever since I had it replaced. I bought a brand new hood, used it once without damage, washed it, and the zipper ripped out in the washer. Once I took it back to the tack shop and exchanged it for a new one, it’s been fine, so I imagine I just bought a lemon. I’ve had it for 3 years and occasionally use it for shows. It still looks nearly brand new. It has a large zipper and buckle girth so is relatively easy to use. The only thing I don’t like is that the lycra is not super-duper stretchy, so even though it’s the correct size, I think it’s a bit restrictive on my horse and that’s he doesn’t like it much (or maybe he just doesn’t like that I’ve thwarted his plans to get dirty…).
My Robin Hood is wonderful. It does have small holes in the neck and the velcro under the chin is just now ripping off, but I’ve had it for over 10 years. I used it when I showed western and halter, when I did hunter braids for huntseat, and now I still use it for my eventing braids on my big guy when I braid him the night before. My halter horse even wore it for an entire winter one year underneath a hood. It has a buckle girth and very long zipper. It’s a lighter weight lycra that is very stretchy, but still sturdy, so I think it’s pretty comfortable for the horse. Assuming they’re still made like they were 10 years ago, I would highly recommend Robin Hoods. I’m actually planning on replacing mine this season with a new Robin Hood.
ETA: Apparently Robin Hoods are expensive- $70 for the same one I have (http://www.robinhoods.com/ecommerce/all-robinhood-products/6oz-robinhood-solid.html). But considering that mine has taken a fair amount of abuse over the years and still looks as good as it does, I’d consider the upfront cost worth it.
