The Backpacker's Packing List

Two kits built around ultralight principles: a weekend overnight under 20 pounds, and the pared-down thru-hike starting line under 12 pounds base weight.

Updated April 13, 2026 · 2 scenarios

Quick answer

A backpacking packing list centers on the Big Three (pack, shelter, sleep system), targeting a total base weight under 20 lbs for a lightweight setup or under 10 lbs for ultralight. Add the Ten Essentials, a stove and fuel, water filter, 3,500 to 4,500 calories per day of high-density food (100+ calories per ounce), moisture-wicking layers, and zero cotton. Thru-hike kits add resupply strategy, a bear canister where required, and backup navigation.

Backpacking gear lives or dies by base weight, the total weight of your pack minus consumables (food, water, fuel). A lightweight base weight is under 20 pounds. Ultralight is under 10. Super ultralight starts under 5. Most new backpackers carry 30 to 40 pounds on their first trip and learn by day two that weight equals suffering.

Cut weight from the Big Three first: pack, shelter, and sleep system. The Big Three typically account for 60 to 70 percent of your base weight, so shaving two pounds from each one (6 pounds total) changes the entire trip experience. Target under 3 pounds per Big Three item to cross the ultralight threshold. A 50L pack under 2.5 lbs, a 2-person tent under 2.5 lbs (or a single-wall shelter under 1.5 lbs), and a 20°F down quilt around 1.5 lbs is the proven trinity.

Food is where thru-hikers really separate from weekend warriors. On a weekend trip, you can bring whatever tastes good. On a thru-hike you optimize for calories per ounce. Target foods with 100 to 125+ calories per ounce: nut butters, olive oil, cheese, salami, tortillas, instant potatoes, cocoa nibs, and dense bars. Plan 3,500 to 4,500 calories per day on trail, and 5,000+ for cold weather or big mileage days.

Built into every category is the Ten Essentials from the Mountaineers: navigation, sun protection, insulation, illumination, first aid, fire, repair kit, nutrition, hydration, and emergency shelter. Do not shave weight here. These keep you alive when the trip goes sideways.

Packing Tips

  1. 1 Target a base weight under 20 lbs for lightweight, under 10 lbs for ultralight. Base weight excludes food, water, and fuel. Everything consumable is carried separately.
  2. 2 Cut weight from the Big Three first: pack, shelter, sleep system. Two pounds off each (6 lbs total) changes the whole trip. Aim for under 3 lbs per Big Three item.
  3. 3 No cotton anywhere. Cotton holds 25 times its weight in water and loses all insulating value when wet. Merino wool and synthetic fabrics (nylon, polyester) are the only acceptable base layers.
  4. 4 Target 100 to 125+ calories per ounce for food. Nut butters, olive oil packets, cheese, salami, and instant potatoes crush freeze-dried meals on density. Plan 3,500 to 4,500 calories per day.
  5. 5 Use a trash compactor bag as a pack liner instead of a rain cover. Rain covers fail; liners do not. Keeps sleeping bag and insulation dry no matter what.
  6. 6 Carry the Ten Essentials on every trip: navigation, sun protection, insulation, illumination, first aid, fire, repair kit, nutrition, hydration, emergency shelter. These stay in the pack even on a summer overnight.
  7. 7 Break in trail runners or boots at home on multi-hour walks with a loaded pack. New footwear on night one is the single most common trip-ender.
  8. 8 Drop a trip plan with someone reliable: trailhead, route, expected return, and when to call search and rescue. A satellite messenger (Garmin inReach Mini) is $350 of cheap insurance in no-service terrain.

Frequently Asked Questions

What is base weight and why does it matter?
Base weight is the total weight of your pack minus consumables (food, water, fuel). It is the one number ultralight backpackers optimize because food and water weight vary trip to trip. Under 20 lbs is lightweight, under 10 lbs is ultralight, under 5 lbs is super ultralight. A typical total pack weight is base weight plus 2 lbs of water (1 liter = 2.2 lbs) plus 1.5 to 2 lbs of food per day. A 10 lb base weight for a 3-day trip ends up around 18 lbs total at the trailhead.
What are the Big Three in backpacking?
The Big Three are your pack, shelter, and sleep system (sleeping bag or quilt plus sleeping pad). They account for 60 to 70 percent of your base weight and the bulk of your gear budget. Target under 3 pounds per item to cross into ultralight territory: a 50L pack under 2.5 lbs, a 2-person shelter under 2.5 lbs, and a 20°F quilt around 1.5 lbs. These are the first items to upgrade when lightening your kit.
How much food should I pack per day for backpacking?
Plan 1.5 to 2 lbs of food per day, totaling 3,500 to 4,500 calories for most hikers. Calculate roughly 16 to 25 calories per pound of body weight depending on terrain and weather. Target foods with at least 100 calories per ounce (nut butters, olive oil, salami, cheese, instant potatoes, cocoa nibs), and aim for 25 to 35 percent fat for dense calories. Thru-hikers burning 5,000 to 6,000 calories per day often cannot eat enough to keep up, so calorie density matters more the longer you hike.
What are the Ten Essentials?
The Ten Essentials are the core safety items the Mountaineers developed to keep backpackers alive when trips go wrong: navigation (map and compass, GPS), sun protection (sunscreen, sunglasses, hat), insulation (extra layers), illumination (headlamp with spare batteries), first aid, fire (lighter and tinder), repair kit and tools, nutrition (extra food), hydration (extra water and treatment), and emergency shelter (bivy, tarp, or space blanket). Carry them on every trip, even a simple summer overnight.
Do I need a tent or will a tarp work for backpacking?
Both work. A double-wall tent is the beginner-friendly choice: easier to pitch, bug-proof, and handles any conditions. A single-wall shelter (Zpacks Duplex, Durston X-Mid) saves 1 to 2 lbs but requires trekking poles to pitch and can condensate in humid conditions. A full tarp saves even more weight but offers no bug protection, so you pair it with a bug bivy. Most thru-hikers end up with a single-wall Dyneema tent after their first 500 miles.
What should I NOT bring backpacking?
Skip cotton clothing in all forms (dangerous when wet), jeans, a full-size camp pillow, a camp chair (backpacking versions are luxury weight), a heavy multi-tool (Swiss Army Classic is 0.8 oz and covers 90% of needs), hardback books, full-size toiletries, glass containers, a second headlamp, and a backup pair of shoes. Each 'just in case' item compounds. The rule of thumb: if you did not use it on the last 3 trips, it stays home.
How do I filter water while backpacking?
The Sawyer Squeeze is the gold-standard hollow-fiber filter: cheap ($40), light (3 oz), and nearly indestructible. Pair with a CNOC 2L dirty bag for easy filtering. Backflush with the included syringe every few days to keep flow rate up. For viruses (rare in the US, common internationally), add Aquatabs or boil. For freezing conditions, filters can crack if they freeze wet, so sleep with the filter in your quilt or switch to chemical treatment.
How do I prevent blisters on a long hike?
Four principles: (1) break in footwear at home, never on trail; (2) use merino or synthetic socks, never cotton; (3) keep feet dry with sock changes at lunch and dry sleep socks at camp; (4) apply Leukotape to hot spots BEFORE they become blisters. Many thru-hikers also wear Injinji toe socks under wool socks to eliminate toe-on-toe friction. If you feel a hot spot, stop within 5 minutes and tape it. Ignoring it for 30 minutes turns a warning into a two-day injury.
How long does it take to plan a thru-hike?
Most thru-hikers spend 8 to 12 months planning a 4-to-6-month trail like the AT, PCT, or CDT. Major milestones: 12 months out (apply for permits, start gear research), 9 months out (training hikes, save money), 6 months out (book flights to trail start, finalize gear), 3 months out (shake-down overnight, resupply strategy), 1 month out (start packing resupply boxes, tie up life logistics). The PCT permit lottery opens in November for following spring; the AT has no lottery but recommends voluntary registration.
Do I need a bear canister for backpacking?
Depends on location. Required in Yosemite, Sequoia, Kings Canyon, Inyo, Rocky Mountain NP, Olympic, and much of the High Sierra on the PCT. Black bear country like the Appalachians allows hanging food (PCT-method bear hang) or an Ursack Major, a Kevlar-fiber food bag. Grizzly country (Glacier, Yellowstone, northern CDT) often requires a hard-sided canister. Check the specific permit requirements before the trip. BearVault BV500 is the most common Sierra-approved model; Ursack is lighter where allowed.
