Ultralight Backpacking Packing List for Light, Fast Trips

How to Use This List

Treat this as a starting template, not a fixed formula. Your list should change with the season, terrain, trip length, and how remote the area is. Weigh each item and record it in a spreadsheet or gear-list tool so you can see where the weight is.

Ultralight is often defined as a base weight (everything except food, water, and fuel) of roughly under 10 lb (4.5 kg), but this is a convention rather than a requirement. For background, see our ultralight backpacking guide.

The Big Three

Backpack: a lighter pack sized for your load, often in the range of about 40 to 55 liters for multi-day trips, with a pack liner or rain cover.
Shelter: a tent, trekking-pole shelter, or tarp setup, with stakes and guylines.
Sleep system: a sleeping bag or quilt rated for the lowest expected temperature, and a sleeping pad.

Sleep Extras

Pillow or stuff sack filled with spare clothes (optional)
Ground sheet or footprint if your shelter needs one
Earplugs (optional)

Clothing

Wear one outfit and carry the rest:

Base layer top (and bottom for cold weather)
Insulating jacket (down or synthetic)
Rain jacket (and rain pants where conditions warrant)
Warm hat and lightweight gloves
Spare socks (see best material for hiking socks)
Sun hat and sunglasses
Underwear and sleep layer as needed

Kitchen, Water, and Food

Stove, fuel, lighter, and pot (or no-cook setup)
Spoon and a mug or reusable container
Water treatment (filter or chemical)
Two water bottles or a collapsible bladder
Food bag and a cord, or a bear canister or hanging system if required where you are hiking

Planning ideas are in our guide to food for ultralight backpacking.

These items usually shouldn’t be cut for weight:

Map and compass, plus a phone with offline maps
Headlamp with spare batteries
First aid kit and any personal medications
Fire starter
Emergency blanket or bivy
Sun protection and insect repellent
Whistle
Satellite messenger or personal locator beacon for remote trips (optional but worth considering)

Hygiene

Toothbrush and a small amount of toothpaste
Trowel and toilet paper, with a bag to pack out used paper if required
Hand sanitizer
Small amount of soap or wipes as needed

Electronics

Phone
Small power bank and charging cable
Camera (optional)

Items Often Left at Home

Camp chair, large knives, and heavy multitools
Extra clothes beyond your layering plan
Full-size toiletries
Duplicate lights and gadgets

Adjusting for Conditions

Cold or shoulder season: warmer bag or quilt, a more insulated pad, extra insulation, and a stove for hot drinks.
Hot, dry trips: more water capacity, sun protection, and extra checks on water sources.
Wet or windy trips: a more weather-resistant shelter and reliable rain gear.
Longer trips: more food and a plan for resupply, with a lighter kit elsewhere to compensate.
