In plain English

A lighter backpack is easier on your legs, back and feet. The trick is knowing where the weight really is. Most of it usually sits in three big items: the backpack itself, your tent and your sleeping bag. Swapping one of those for a lighter version often saves more than removing a dozen small things.

Hikers talk about 'base weight'. That is everything in your pack except food, water and fuel, the things you use up as you go. It is a fair way to compare gear, because your food bag shrinks every day but your tent doesn't.

Cutting weight should never mean leaving safety gear behind. Keep a map, a first-aid kit, a light, spare warm clothing and water. Choose lighter versions of those things if you like, but carry them. A good start is weighing each item on a kitchen scale and writing it down.

How to Reduce Your Backpack Weight — demonstrated step by step, hands and gear only

Reducing backpack weight comes down to identifying which items carry disproportionate weight for their function, then replacing or removing them in order of impact. The biggest gains come from the few heaviest items in a pack, not from trimming a dozen small accessories, though both matter once the big items are addressed.

Which gear categories give the biggest weight savings?

The backpack, shelter, and sleep system — often called the "big three" — typically account for half or more of total base weight, so upgrading these three items first delivers the largest weight reduction per dollar spent. Cookware, clothing, and accessories matter, but their combined weight rarely rivals what the big three alone carry.

A traditional framed pack built for load-hauling comfort weighs meaningfully more empty than a frameless ultralight pack, and that gap alone can account for several pounds of base weight before any other gear is considered. The same pattern holds for shelters and sleep systems: a freestanding double-wall tent weighs more than a trekking-pole shelter, and a down quilt weighs less than a comparable synthetic mummy bag for a similar temperature rating.

How much weight can be cut from food and consumables?

Food weight can be trimmed by pre-portioning meals to what each day needs and choosing calorie-dense, low-water-content meals instead of carrying padding or backup portions. Fuel weight drops when a hiker calculates burn time for planned meals instead of carrying a full canister out of habit.

Dehydrated and freeze-dried meals weigh far less per calorie than fresh or canned food, since removing water removes most of the weight. Water itself weighs about 2.2 pounds per liter, so carrying only what's needed between reliable water sources — rather than a full supply for the whole day — meaningfully cuts loaded pack weight, separate from base weight. Because food, water, and fuel are consumed as a trip progresses, loaded pack weight naturally drops day by day, which is exactly why base weight, not loaded weight, is the number gear systems get compared on.

Does cutting pack weight mean sacrificing safety or comfort?

Cutting pack weight doesn't require dropping essential safety items — it means choosing a lighter version of the same item, like a lighter headlamp or a first-aid kit sized to the trip, rather than leaving safety gear behind. The trade-off shows up more in comfort and durability than in safety, if weight is cut thoughtfully.

A thinner sleeping pad saves weight but offers less cushioning and sometimes less insulation. A frameless pack saves weight but offers less structure for hauling heavier or oddly shaped loads. Lighter shelter fabrics like DCF cost more and can be less abrasion-resistant than heavier nylon, trading durability for weight savings. None of these trade-offs require dropping the basic safety items a hiker carries on any trip — navigation, first aid, an emergency layer, and a way to signal for help stay non-negotiable regardless of a weight target.

Where do experienced ultralight hikers cut weight first?

Experienced ultralight hikers typically cut weight in this order: the big three, then clothing layers down to a single insulating piece, then camp comfort items like a pillow or seat, and finally redundant tools and packaging. This sequence follows where the largest weight savings live rather than cutting evenly across every category.

Multi-use gear removes weight without removing function: trekking poles that double as shelter poles, a stuff sack that doubles as a pillow, or a phone that replaces a separate camera and GPS unit. Decanting toiletries into smaller containers and removing retail packaging from food and gear are small cuts that add up over a full gear list. Thru-hikers, who carry the cumulative weight of every choice over hundreds of miles, tend to push hardest on base weight for exactly this reason — a few ounces saved per item compounds heavily across a trip that lasts months rather than days.

Frequently Asked Questions

It depends on where those ounces come from. Cutting weight from the big three — pack, shelter, sleep system — usually delivers the biggest gains per dollar. Spending the same money to shave ounces from an already-light accessory rarely moves total base weight enough to matter.

Where the weight categories come from

Base weight is a community term, not a standard set by any official body. The Appalachian Trail Conservancy defines it as pack weight with all gear, minus consumables such as food, water and fuel, and calls the pack, shelter and sleeping bag the 'big three', usually the heaviest pieces of gear.1 Gossamer Gear sets the categories at under 20 lb for lightweight, under 10 lb for ultralight and under 5 lb for superultralight,2 and Zpacks says ultralight is generally agreed to mean 10 lb or less.4 Both are pack makers, so the thresholds are industry convention rather than science.

The claim that the big three make up half or more of base weight, and the weight ranges in this page's table, are common estimates rather than sourced figures. They are a reasonable way to see where to look first, but your own gear list, weighed item by item, is the only number that tells you where your weight is.

What the research says about carrying less

In a lab study, metabolic energy use during walking rose roughly in a straight line with backpack load, by about 7.6 watts per extra kilogram.3 UK infantry testing with much heavier loads found metabolic cost rising about 1% for each extra kilogram carried.5 Weight on your feet counts far more: each kilogram added to the foot raises energy use by 7 to 10%.6 That makes footwear one of the most effective places to save weight, though the right shoe still depends on terrain and load.

Hikers often carry more than guidelines suggest. In a study of Appalachian Trail long-distance backpackers, packs averaged 25% of body weight for men and 27.9% for women, above the popular 20% guideline.7 That 20% figure is itself a hiking-community rule of thumb with no primary source; Deuter, a pack maker, says people can carry a maximum of 20 to 25% of body weight.8

The food-per-day figure is a rule of thumb

A range of 1.5 to 2.5 pounds of food per person per day is widely repeated among backpackers, but no source in this site's library backs it, so treat it as a starting point to adjust, not a fixed rule. The most detailed official calorie figures available are military: the National Academies put energy needs in the cold at 3,400 to 4,300 kcal a day for a 75 kg man.9 Those apply to soldiers in cold field conditions, not to a summer weekend.

There is also a limit to how far food can be trimmed on long trips. Research on endurance events found sustained energy spending plateaus below three times basal metabolic rate, and that the digestive system can only supply about 2.5 times that rate; spending more draws on body stores.10 Cutting food weight too hard on a long trip simply means running a deficit.

Cuts that should never happen

NPS describes the Ten Essentials as items that help in minor injuries, sudden weather changes or unexpected emergencies.11 It advises starting with a pre-made first-aid kit and adapting it to the trip and your own medical needs, and recommends a headlamp as the light source because it is hands-free.11 Swap for lighter versions, but keep them all.
