Where do the biggest weight savings come from?

The "big three" — shelter, sleeping bag and backpack — typically account for 60-70% of base weight. Switching from a 2.5kg tent to a 1kg tarp shelter saves 1.5kg alone. After the big three, focus on worn weight (lighter boots) and eliminating redundant items.

When is saving weight not worth it?

Safety gear should never be cut for weight savings. A first aid kit, headtorch, map, compass and emergency shelter are non-negotiable. Also consider durability — ultralight gear often trades longevity for weight, which may not suit everyone.

Should I weigh everything in grams?

Yes. Weighing every item in grams is the foundation of lightweight packing. Kitchen scales work well. Many small items add up — 20 items at 30g each over their lighter alternatives costs 600g. Track everything in a spreadsheet or gear list app.
