What Ultralight Backpacking Means
Ultralight backpacking is an approach to carrying less weight on multi-day trips by choosing lighter gear, bringing fewer items, and relying more on skills. The usual yardstick is base weight: everything in your pack except food, water, and fuel (consumables).
Common rules of thumb are loose and vary by source:
- Traditional: base weight often above roughly 20 lb (9 kg).
- Lightweight: roughly 10 to 20 lb (4.5 to 9 kg).
- Ultralight: generally under about 10 lb (4.5 kg).
These are conventions, not rules. Plenty of hikers go lighter with a few changes and never chase a number. What matters is that you are comfortable and prepared for the conditions you will actually face.
Why Go Lighter (and When It May Not Be Worth It)
A lighter pack can mean less strain on your feet, knees, and shoulders, and it can make longer days feel easier. Many hikers also find that fewer items means faster camp chores and simpler packing.
There are trade-offs. Lighter gear can be less durable, less roomy, or less forgiving in poor weather. If you carry heavy loads for work, travel with children, or head into harsh conditions (deep cold, long snow travel, or remote areas), you may reasonably choose a heavier, more robust kit.
Start by Weighing What You Own
You can’t improve what you haven’t measured. Weigh each item on a kitchen or postal scale and record it in a spreadsheet or a gear-list tool. Sort items into categories such as shelter, sleep, clothing, kitchen, and electronics.
Most people discover that a small number of items account for most of their weight. That points you to where changes help most. For a ready-made category structure, see our ultralight backpacking packing list.
The Big Three: Pack, Shelter, and Sleep System
The pack, shelter, and sleep system are usually the heaviest items, so they are the typical starting point.
Backpack
Lighter packs often use thinner fabrics and fewer features, and many have minimal or removable frames. A lighter pack is only comfortable if your total load fits its rated capacity, so reduce what you carry first and then choose the pack. Buying the pack last often saves money and size.
Shelter
Options range from standard tents to trekking-pole tents, tarps, and floorless shelters. Lighter shelters often trade away some weather protection, bug protection, or ease of setup. Practice pitching at home before relying on one in the field.
Sleep System
Your sleeping bag or quilt and sleeping pad must keep you warm for the lowest temperatures you reasonably expect. Quilts can save weight by omitting insulation that compresses under you, and a pad supplies the insulation underneath. Check the manufacturer’s temperature ratings and consider the pad’s insulation value (R-value) for cold ground.
Cooking, Water, and Food
Many hikers shave weight here with a small stove and a single pot, or by skipping the stove and eating cold meals. Water treatment can be done with lightweight filters or chemical options, and some hikers carry fewer bottles when water sources are frequent. Always confirm water availability before relying on it.
Food is often the heaviest consumable. Choosing calorie-dense options helps; see our guide to food for ultralight backpacking for planning amounts and ideas.
Clothing and Footwear
A layering system you can mix and match usually beats a larger pile of single-purpose items. Carry what you need for the coldest and wettest conditions you might meet, not only the forecast high. Many lightweight hikers choose trail runners over boots, though ankle support and traction needs differ from person to person, particularly with heavier loads or rough terrain.
What Not to Cut: Safety First
Weight savings should never remove the items that protect you in an emergency. Keep, at minimum, a way to navigate, a light source, sun protection, a basic first aid kit, a fire-starting method, a shelter or emergency insulation, extra food, extra water or treatment, and extra clothing. These are often called the Ten Essentials.
Consider adding items based on the trip: a satellite communicator or personal locator beacon in remote areas, bear-resistant food storage where required, and rain gear in changeable weather. Check local regulations and land manager advice for the area you are visiting.
Skills That Replace Weight
Lighter packs lean on knowledge. Useful skills include reading weather and terrain, navigating with a map and compass, choosing campsites, managing layers to avoid sweating, pitching your shelter in wind, and treating water. Gaining these through shorter trips close to home helps you judge what you can safely leave behind.
A Step-by-Step Approach to Lightening Your Load
- Weigh everything and record it.
- Remove duplicates and unused items. Review what you didn’t use on your last trip (excluding emergency gear).
- Repackage food, toiletries, and first aid into only the amounts you need.
- Upgrade the Big Three gradually, starting with whichever item is heaviest and most replaceable.
- Test close to home before a long or remote trip.
- Adjust after each trip based on comfort and what you actually used.

Common Mistakes
- Buying expensive gear before removing unnecessary items.
- Cutting safety items or clothing to hit a number.
- Choosing a shelter or bag that isn’t suited to the conditions.
- Carrying too little food or water because of weight goals.
- Skipping a practice trip with new gear.
FAQ
Is ultralight backpacking safe?
It can be, when your gear and skills match the conditions. The risk comes from cutting essentials or heading into conditions your lighter kit can’t handle. Keep emergency and weather-protection items and build experience gradually.
Do I need to spend a lot of money?
Not necessarily. Leaving behind unneeded items costs nothing, and many upgrades can wait or be bought used.
What is a good base weight to aim for?
There isn’t one correct figure. Treat the ranges above as guidelines and choose a weight that keeps you comfortable and safe on your typical trips.
