Looking for some suggestions for a large, durable, but still stylish bag for a frequent flyer. I generally carry two laptops (one personal/one business), plus some other gadgets, chargers, documents, and a few other miscellaneous items. I was thinking of the filson 258 or maybe a Tumi-- something in that vein. Would love to hear some suggestions. My price range is probably up to around 350, but I'd be open to spending more for the right bag. Thoughts?
