My Frost River simple brief went up nearly 50% in price in a year! A pretty incredible increase which cannot be attributed to foreign currency fluctuations.
The Ernest Alexander weekender however is optimized for carrying clothes rather than gear. And clothes tend to be more voluminous and less heavy than gear. Consequently, the bag is lighter and less boxy than Filson equivalents. And the capacity is high for its relatively small footprint. So I may give it a whirl. It does not have that "throw it in the back of pickup during a hailstorm" appeal of Filson but on the other hand l, it may look far better with your sport coat when you walk into the business class lounge.
