The gap between this pack and the rest of the guide shows up the moment you shoulder a real load. Weight settles onto the hipbelt and stays there instead of dragging at your collarbones, and the suspended back panel holds the pack off your spine — on a long climb that reads as less fatigue rather than more ventilation. That is what the premium buys, and it is why this is the top pick rather than simply the expensive one.
The rest of the spec sheet backs it up. Sixty-five liters, four pounds, and a raincover in the box, so there is no separate purchase and no hunting for one that fits. The sleeping bag compartment has a removable divider, which opens it into one long space for a bear canister or a bulky tent, and the curved zip on the side reaches the middle of the main body without unpacking from the top. The floating lid cinches down over a half-empty pack and carries lash points for a wet shell.
Fit is the one thing to settle before you order. This listing is the large–extra-large harness, so check your torso measurement against the size chart instead of assuming; a pack this good on the wrong back is just an expensive pack. The All Mighty Guarantee is the other quiet argument for it — you notice the value of a repair promise the first time a buckle fails, not before.
Four pounds for 65 liters is the figure we keep returning to. It is lighter than two of the cheaper packs here, and both of those are harder work when they are full.

If you backpack more than a few times a year, this is the pack we point you to: it carries a full load on your hips and weighs four pounds doing it.
