You can look at blankets from Hudson Bay Company (Canada), Pendleton Mills (Oregon), Woolrich (Pennsylvania), Fairbuilt Mills (Minnesota) and see a lot of similarities. They are are warm and heavy and have been made for over 100 years. Which are the best? The answer is, it depends.
The HBC blanket, in King (which is 8 points for the plebian, as points designates the size), weighs 10 pounds, the Pendelton 8.5, and the Fairbuilt is currently 6.5, so they are clearly different weights of wool (thicknesses). So if you want the heaviest weight, get the HBC. You can even get it with fur sewn onto the blanket, such as this one.

For the Rocky Mountains, Pendleton is more iconic and has more contemporary and old southwest and SW native American patterns than HBC. The weight is slightly less and, for the price, you could buy almost two Pendletons now for one HBC, so it makes sense in terms of the amount of wool used. The Fairbuilt is even less thick and the price reflects that, but these blankets are very popular in Minnesota and surrounding areas. So get what you like, but understand why the prices are different, as the amount of wool used is different for each brand. The quality is exceptional on all of these.
