Mike Newlin wrote a review of Granite Gear Vapor Trail Backpack - 3300-3900cu in on August 5, 2003
I recently took a six day trip in Rocky Mountain National Park where we summitted Long's Peak (14,200 ft.) and Hague's Peak (13,500 ft.). I took the Vapor Trail since we were only out 2-3 nights at a time. I was able to carry everything I needed, less the tent, and was fine. The only complaint I have about the pack is that when the pack is full, it is difficult to get the Nalgenes back in their pockets. Other than that, it was great. And since it only weighed two pounds, I used it as my day pack when making the summit trips.
