I like the Dover Northwinds. Neither of my boys are narrow-chested, but plenty of the horses at the barn are. These blankets have plenty of adjustments in the chest and are very durable (least in my opinion... about half the horses at the barn (roughly 12) have the same blanket... and they are all still holding up, seasons later).
If you can't get one exactly right 'off the rack', if everything fits but the neck hole is too big and it sags low on the shoulders, you can take it to a awning or saddle maker and have darts sewn in the shoulders to make the neck smaller. I did that for some of my TB yearlings who were built like fence rails.
I adore the Rambo Wug (purple) for my horse, who is 17h but wears a 48" girth...yes he is NARROW. He also has huge withers/shoulders and this is the only blanket that does not rub.
A friend of mine has used the Dover Hug blankets on her narrow TB and also liked them. Cheaper than the Rambo as well.
My guys is also tall/narrow/shark-finned. He's 16.3 and wears a 48"-50" depending on the girth. His withers are HUGE. He has a Rambo original heavyweight (81") in it's 7th season and I love how it fits him. It doesn't move and he never gets blanket rubs from it. It also looks brand new after it's cleaned.
I got him a midweight Dover Northwind this year and it's holding up well and fits nicely too, no blanket rubs or anything. Like another poster said, lots of room for adjustment in the chest area. I got him a 78" in this.
Great ideas, just what I was hoping. My poor checkbook is suffering from the recession, so Rambos are out. Will look into the Dover blankets and Shires. Patty Stiller, interesting idea, where did they put the darts? My current blanket, Weathabeta Landa, is in great shape, it just sags at the front and causes rubbing.

I have an extremely narrow chested mule and the only kinds of blankets that work are the "european cut" (cut higher on the neck) ones like Rambo. I order down a size for him as well, ie, he measures a 75, but I go with a 74 for him.
As long as your horse isn't a blanket destroyer, the Dover Hug would probably work for him (only 600 denier). I use them on my narrow-chested Arab, and they're a great fit in the neck, with no shoulder rubs. Not too expensive either - at this time of year, they might very well be on sale.
Schneider's has GREAT blankets at GREAT prices. I have my whole barn hooked on them! I have yet to find a horse that these blankets don't fit. They're also having a great sale right now. Great blanket at a great price and IMO they're a better blanket than anything else on the market.
I would make sure to get a VFit one, as the Euro fit doesn't have a back seam and tends to slip on occasion. The VFit fit likes a glove on all of my guys!
