Pack Features Less is more. Stay away from packs with too many bells and whistles. Evaluate features with these two questions in mind: 1) What is the feature’s main function? and 2) Will I use it?\r\n\"For a big expedition like Denali, I want a pack that is simple, lightweight and can handle the load. I stay away from packs that are overbuilt with pounds of zippers and extra straps. I just want something with a large main compartment and a solid suspension system.\" Seth Waterfall
