Probably one of the backpacks, but I’m just guessing. I’ll say a couple things as someone with 3 Vanquest bags – the material (1000D nylon?) is very rugged and will ruin a nice dress shirt, so be careful what you’re wearing when you use these bags. The Skycap bag is interested because it’s sized for airline carry-on, not saying it’s perfect for BOB, but for someone who flies a lot there’s some interesting options there I think. I just know it’s a good company, they care about their customers, their products seem to be built like brick S-houses, and have lifetime warranties… (edit: they’re also notorious for having lots of compartments)
Why did you not include Vanquest in this list?
