Backpacking Base Weight: What the Big Three Weigh and Cost
How we did this: we built three Big Three kits (pack, shelter, sleep system) only from gear whose weight and price we checked on the makers’ own pages on 29 Sep 2026, at comparable sizes: packs in medium, sleep systems rated 30°F, shelters without stakes. We have not field-tested these kits.
Backpacking base weight is everything you carry except food, water and fuel. The biggest share is usually the Big Three: pack, shelter and sleep system. Built from makers’ figures, a value Big Three weighs 4.5 lb for about $814, and the lightest 3.0 lb for about $1,457.

| Upgrade | Saves | Costs | Per ounce |
|---|---|---|---|
| Value kit to middle kit | 12.8 oz | $335 | $26 |
| Middle kit to lightest kit | 10.7 oz | $308 | $29 |
| Value kit to lightest kit | 23.5 oz | $643 | $27 |
The Big Three get lighter in steps of a pound or more, but each step costs more money. Before buying, try the free step: weigh everything, and leave behind what you did not use on your last trip.
How to reduce your base weight, step by step
- Weigh everything. A kitchen scale and a spreadsheet show where the ounces are. Record the maker’s size and what is included, because makers count stakes, poles and belts differently.
- Remove before you replace. Anything you did not use on your last two trips, apart from safety items, is the cheapest weight to cut.
- Start with the Big Three. They are the largest items, so the savings are biggest, as the table above shows.
- Match the pack to the new load. A lighter load lets you use a lighter pack, but stay within its load rating; frameless packs like the Gossamer Gear Kumo 36 are rated 20 lb for comfort.
- Then the small items. Dry bags, cook kit and electronics add up; see our per-liter dry bag comparison.
