I saw one of the Filson Weatherproof Leather Original Briefcases today - looked beautiful, seems extremely well made (no surprise). Wondering if anyone has one of these and can offer any feedback? I'm on the hunt for a leather work bag and it's looking like Filson or Saddleback. Would've been Saddleback a couple of years ago if the didn't perseverate on all the damned D-rings (useless to me). Appreciate any reviews of the Filson. Thanks!
