Equipment travels when its owner does. The plan is reasonable. The majority stays in the bag. The causes are consistent. A trip has less spare capacity than a week at home. A week away contains fewer free hours than an ordinary week. The overhead. Tiredness accumulates differently away. Depletion arrives earlier. Nothing can be done. An activity needing a particular surface, cm-strategies piece space or quiet may find none of them. Reduce rather than optimise.

Half the equipment and twice the use is the pattern most people arrive at eventually. What to leave is the harder question. Size correlates with non-use. Setup discourages. The minimal version of an activity travels considerably better. Nearly always. Hiring at the destination deserves more consideration than it gets. The arithmetic favours it. Baggage charges, the risk in transit, the difficulty of moving it. Hired equipment is rarely as good and is adequate for a week.

Transit is hard on things. Which argues for leaving anything valuable or irreplaceable at home. A clear test. What actually gets used away differs from what gets used at home. The portable form. Noting afterwards what was used and what was not improves the next attempt. Most people repeat the same packing error for years. The travellers who use what they carry hired anything bulky at the destination.
