How did we cut our pack weight by 30%?

The starting point: a 16 kg overnight pack

We began by doing the unglamorous thing. We emptied the pack onto the floor and weighed every single item on a kitchen scale, writing each number down. Base weight, before food, water and fuel, came to 16.2 kilograms.

For an overnight or short multi-day walk in Australian conditions, that was heavy. Not dangerous, but heavy enough that the last hours of each day were a grind we had simply accepted as normal.

The list told a story before we changed a thing. A 2.6-kilogram tent, a cast-iron pan carried for nostalgia, three litres of water for a route with reliable refills. And a pile of redundant clothing layers that duplicated each other.

Seeing those numbers in writing was the actual turning point. You cannot fix a weight you have never measured, and the biggest items are rarely the ones you would guess.

Where the grams actually hide

The classic advice is to attack the big three: shelter, sleep system and pack. We found that true, with a local twist. In dry-country Australia, water carrying is a fourth category that can outweigh all of them on some routes.

Our tent and its footprint, pegs and poles were the single heaviest item at 2.6 kilograms. The sleep system came next. Then the pack itself, then water.

The surprising dead weight was spread through small duplications. Two jackets that did nearly the same job. A pan, a kettle and a mug when one pot served all three. Spare stuff sacks, a second headlamp, three times the washing-up sponge anyone needs.

The lesson from the spreadsheet was blunt. Buy lighter for the big items, but get the biggest savings free by refusing to carry duplicates.

The shelter swap: our biggest single win

Replacing the 2.6-kilogram tent with a well-ventilated single-wall shelter brought the shelter category down to about 1.1 kilograms. That one change was roughly 1.5 kilograms, the largest single cut of the whole project.

We were deliberate here, because shelter is a safety item and this is not a place to cut recklessly. The new shelter was chosen for wind and rain competence, not just for its number on the scale. A lighter tent you cannot trust in a storm is not an upgrade.

The lighter design traded a little room and some ease of pitching for the saving. On a short walk that suited us, carrying a two-person tent solo was the real waste, not the fabric.

Weigh the whole shelter system, too. Skinny pegs, a shorter pole and ditching the footprint on soft ground added up to hundreds of grams the tent label never shows.

Water: carry less, plan to refill

The second big win was water, and it came from a change of thinking rather than a purchase. We had been carrying a flat three litres for every trip out of habit. On a route with dependable, treatable water, that was carrying roughly 1.5 kilograms we did not need.

We moved to carrying 1.5 litres between known sources, with a small filter and a refill plan, cutting around 1.5 kilograms off the typical load. On genuinely dry stretches we simply carried more; the point was to match carriage to the route instead of a fixed habit.

This is the safety-sensitive part of the project, and we treat it seriously. Before reducing water on any Australian walk we checked current source conditions. We left a water plan with a trusted contact, in line with the remote-trip guidance land managers publish.

A lighter water carry is only ever lighter when the water is actually there. Get that wrong and it is not ultralight, it is dangerous.

Clothing, cookware and the expensive dead ends

Clothing was the cheapest win. We removed the duplicated layer and settled on one insulated jacket plus a rain shell. We chose pieces that worked across the temperatures we expected, not one garment per worst case.

The cookware swap was the one that flopped. We paid real money to trade the cast-iron pan for a titanium pot, saving a few hundred grams. It worked. But for a fraction of the cost, we could get most of the way there by dropping a pan carried out of habit.

A few small upgrades we expected to pay off did nothing meaningful. A lighter stuff sack, a cut-down toothbrush, a titanium peg. Fine individually, invisible together. They made good shopping and poor project targets.

The honest pattern held all the way through: free edits beat paid ones. Removing duplication gave us more than most of what we bought.

How to repeat it on your own pack

You can copy the method without buying our exact gear. Weigh your base load and write it down; you cannot manage a number you have never measured.

Sort the list biggest to smallest, then work from the top. Shelter, sleep, pack, water. A gram off the heaviest item is worth ten off the lightest, and it is far easier to feel.

Before any purchase, hunt for the free wins: duplicates to merge, spares to leave home, and items that exist only because you always carried them. Weigh the pack again after each change so the result is real, not hoped for.

Finally, protect the margin. We never cut safety, navigation, first aid or the ability to survive a cold, wet night. The goal was a lighter pack that was exactly as capable, and at 11.4 kilograms we got one.

Frequently asked questions

Was a lighter pack worth the money we spent?

Partly, and the split is instructive. The shelter change was worth every dollar because it cut the heaviest item and kept us warm and dry. The expensive cookware and tiny accessories were not; they saved little for the cost. If we did it again, we would buy only the shelter and the sleep system. Then we would take the rest through free edits, like cutting duplicated clothing and spares. Most of the 30 percent came from decisions that cost almost nothing.

What is base weight, and why track it instead of total pack weight?

Base weight is everything you carry except consumables, meaning without food, water and fuel. We tracked it because it reflects your gear choices. Total weight swings instead with trip length and how much water the route demands. If you optimise base weight, every trip gets lighter regardless of distance. If you only watch total weight, a long carry of food can hide a heavy tent, and you end up fixing the wrong problem.
