Gear lists grow to fill the container you give them. Buy a 65-liter pack “to be safe” and within a season you’ll be carrying 65 liters of safety up every incline — most of it insurance against discomforts you’d barely notice.
The fix isn’t discipline. It’s a smaller container.
Constraint as equipment
The 40-liter rule is simple: no overnight pack bigger than 40 liters, ever, and the pack makes the decisions after that. The sleep system has to compress. The kitchen has to consolidate. The third jacket argues its case and loses. What’s left is a kit where every item earned its spot by displacing something else.
What survives the cut
After two years under the rule, the survivors are boring, which is how you know they’re right: one shelter you can pitch angry in the rain, one insulation layer that works damp, a stove the size of a fist, and a repair kit that fits in a sandwich bag. The exotic stuff — the camp chair, the second lantern, the just-in-case — never makes weight.
The almanac will cover the specific kit piece by piece. But the pack came first, because the container is the most important piece of gear you own: it’s the one that chooses all the others.
