If the weight doesn't concern you, but a cushy back panel does, then the AirContact is an excellent choice

And there are a lot out there

To contrast that, you could also slap a 2200 on the K4 frame for day-hunting purposes

However, for the average backpacker trying to squeeze their life into a backpack we would advise choosing the Fairview 55L
