I emptied my pack onto the kitchen floor after a walk last autumn, mostly to find a set of keys that had gone missing into a pocket, and found a folded emergency blanket in the bottom that I could not remember putting there. It was still sealed. Judging by the dust on it and the fact I had switched packs the previous spring, it had been carried on somewhere near two hundred miles of country track without ever being opened, and it had been in a bag I had complained about the weight of more than once.
The audit I should have done a year earlier
So I did the boring thing and made two piles. Everything I had used at least once in the past twelve months, and everything I had not. The used pile was small enough to be slightly insulting given how full the bag always felt. The unused pile had a stove in it, a first aid kit roughly the size of a paperback, a spare shirt, a multi tool, a second full water bottle, and an actual paperback that I had never once read on a walk because I do not sit down for long enough.
None of that had gone in by accident. Every single item had been added after some specific moment of imagining a situation, and every one of those imagined situations was reasonable. What I had never done was ask whether the situations were likely, or whether the thing I was carrying was the best answer to them.
What came out and stayed out
The stove went first. I had used it exactly twice in two years and both times it was a novelty rather than a need, because I walk for three to five hours and then go home, and I can carry hot tea in a flask if I want hot tea. The paperback went. The spare shirt went, because I could not construct a scenario on a day walk where I needed a clean shirt but not a car.
The big first aid kit was harder, and I want to be careful here because it sounds like I am recommending carelessness. What I did was open it and look at the contents honestly. Most of what was in there addressed injuries that would end the walk and start a phone call. What I actually use, several times a season, is blister plasters, a couple of dressings, tape, and painkillers. So that is what I carry now, in a small bag, and I stopped pretending I was equipped for anything more serious than I was ever going to treat myself on a farm track two miles from a road.
The multi tool went because in three years I had used it once, to tighten a screw on a pair of walking poles I no longer own.
What stayed, and why it earns the space
Water, obviously, though one bottle rather than two, because I know my routes and I know where I can refill. Food, more than I need, because I would rather carry a spare bar than get hungry and short tempered four miles out. Waterproof jacket, always, regardless of forecast. A hat and gloves from about October to about April, because the cost of carrying them is nothing and the cost of not having them on an exposed field edge is a genuinely bad hour.
A phone with charge on it. A paper map for anywhere I do not know well, which is not nostalgia, it is that a map does not run out of battery and shows me the whole valley at once instead of a moving square. And the spare socks, which I have written about before and will keep bringing up because they have rescued more walks than anything else in the bag.
The unglamorous things that unexpectedly earned their place
A folded plastic bin bag, which weighs nothing. It has been a seat on wet grass, a cover for the pack when a strap failed on a rainy day, a place to put boots in the car footwell, and once a way of carrying home a load of rubbish that somebody had tipped in a gateway.
A few metres of thin cord. That has fixed a broken lace, tied a gate that would not stay shut, and lashed a jacket to the outside of the bag when it was too wet to go inside. A small torch, because I have misjudged how quickly the light goes in October more than once and the phone torch chews battery. And a pen, which sounds ridiculous, but I write things on the back of the map and I like having done so.
The counter argument, which I take seriously
Everything above is about day walks on known ground, mostly farm tracks and field paths, rarely more than a couple of miles from a road, in a part of the country where the weather can be nasty but is not dangerous. Change any of that and the list changes with it.
If I were going somewhere genuinely remote, or somewhere I did not know, or up onto ground where the weather can turn properly, then most of what I stripped out would go back in and I would not think twice. Stripping a pack down is not a virtue in itself. It only makes sense once you know your ground well enough to know what you are actually exposed to, and I did not know that in my first year, which is exactly why I carried the stove.
The part I did not expect
The bag got noticeably lighter, which was the point. What I did not anticipate is that it changed how often I went out. A heavy pack is a small piece of friction sitting between you and the door, and there were evenings when the thought of shouldering that thing was enough to make an hour on the track feel like a project rather than a walk.
With a light bag I stopped deciding. I just picked it up. Over a year that has probably been worth more to me than every individual item I removed, which is a strange conclusion to reach from a pile of kit on a kitchen floor, but there it is.
