In plain English

A packing list is simply a checklist of what to bring so you don't forget anything important. For a day hike, it's mostly water, food, a map, a light, first-aid supplies and an extra warm layer. For a night out, you add a tent, a sleeping bag and something to cook with.

Grouping things by job makes the list easier to use: things to find your way, things to drink, things to eat, things to sleep in and things to wear. That way you can see at a glance if a whole group is missing.

Weight matters too, because you carry everything on your back all day. A lighter pack is easier on your knees, feet and back. A common rule says to keep your loaded pack under about a fifth of your body weight, though, as explained below, that number is a rough guide rather than science.

What's the difference between a day-hike and overnight packing list?

A day-hike packing list is built around water, food, navigation, and the ten essentials, with no shelter or sleep system, while an overnight list adds a tent or tarp, a sleeping bag and pad, a stove, and a full day's food per night out. The overnight list typically doubles the pack weight and pushes capacity from a sub-25-liter daypack into the 35–55 liter range.

Both lists share the same starting point. Water, navigation, sun protection, a first-aid kit, and a repair kit don't change much between a three-hour loop and a five-night route — only their quantities shift. What changes is everything tied to spending the night outdoors: shelter, insulation, and cooking gear, none of which belongs on a day-hike list at all.

What gear goes in each category of a hiking backpack packing list?

A hiking backpack packing list breaks into six functional categories: navigation and safety, hydration, food and cooking, shelter and sleep, clothing, and pack-specific accessories. Organizing gear this way, rather than by "what fits where," makes it easier to spot a missing category before leaving the trailhead.

  • Navigation and safety: map, compass, phone with offline maps, first-aid kit, whistle
  • Hydration: bottles or a reservoir, plus a filter or purification tablets for refills
  • Food and cooking: trail food, a stove and fuel canister for overnight trips, a pot, and a spork
  • Shelter and sleep (overnight only): tent or tarp, sleeping bag or quilt, sleeping pad
  • Clothing: moisture-wicking base layer, insulating layer, rain shell, hat, and gloves in cold conditions
  • Pack accessories: rain cover, stuff sacks or packing cubes, and a repair kit
Grouping gear this way also makes trimming easier later, since it's obvious which category is carrying the most unnecessary weight.

How much should a packed hiking backpack weigh?

A packed hiking backpack, including food and water, is generally kept under about 20% of the hiker's bodyweight, a common rule of thumb among trail organizations and gear retailers. A 160-pound hiker, for example, is working toward a fully loaded pack around 32 pounds or less, with day-hike loads sitting far below that ceiling.

Base weight — the pack's weight without food, water, and fuel — is the number most worth tracking, because it's the part a hiker actually controls through gear choices rather than trip length. A lighter base weight leaves more of that 20% budget for food and water on longer trips. The relationship between total pack weight, base weight, and the ten-essentials floor is covered in more detail in pack weight and base weight.

What packing list items change by season?

Season changes insulation, shelter rating, and water strategy more than it changes the packing list's structure. A summer overnight list needs a lighter sleeping bag and less insulation; a shoulder-season or winter list needs a warmer bag, insulated layers, and often a four-season-rated shelter, while the underlying categories — navigation, hydration, food, shelter, clothing — stay identical.

Cold-weather trips also add items that don't appear on a summer list at all: traction devices, insulated water bottle sleeves to prevent freezing, and heavier gloves. Warm-weather trips swap the other direction, trading a heavier bag for a lighter quilt and dropping most insulated layers in favor of one warm layer for camp. A full breakdown of what shifts month to month is covered in seasonal guides, and pack sizing for colder trips with bulkier gear is covered in winter and snow packs.

How does a multi-day list differ from a one-night list?

A multi-day packing list uses the same categories as a single overnight, but scales food, fuel, and consumables by the number of nights rather than adding new gear categories. A three-night trip needs roughly three times the food and fuel of a one-night trip, plus a slightly larger pack to carry it, while the tent, sleeping bag, and stove stay the same items used on the first night.

The main planning shift on longer trips is resupply. Trips beyond about five to seven days often plan a resupply stop rather than carrying every meal from the trailhead, which keeps the pack from growing past a manageable weight. Matching pack volume to the number of nights, rather than buying the largest available size "just in case," is covered in trip length and capacity.

Frequently Asked Questions

Yes. The ten essentials cover an unplanned night or minor emergency, and even a short hike can turn into an unplanned night if weather or an injury intervenes. Each item is small and light; navigation, a headlamp, an extra layer, and basic first-aid supplies fit easily in a daypack under 25 liters.

A beginner list starts with the day-hike core — water, food, navigation, sun protection, an extra layer, first aid, and a headlamp — then adds shelter and a sleep system only once overnight trips are planned. Weighing gear and cutting duplicates before the first trip prevents an overloaded pack from souring the experience.

What the evidence says about the 20% rule

This page describes 20% of body weight as a guideline used widely by trail organizations and retailers. It is widely repeated, but no primary source in this site's research sets it, so treat it as a hiking-community rule of thumb rather than a scientific limit.

Published figures point in different directions. Deuter, a pack maker, states people can carry a maximum of 20 to 25% of their body weight.1 A 2022 review of backpack ergonomics says adult loads in military, hiking and mountaineering settings should generally not exceed 40% of body mass.6 A 2026 study of long-distance hikers found forefoot pressure rose 5.41% with a pack at 10% of body weight and 8.73% at 20%, and that loads above about 10% produced a clear, load-dependent rise.2 US Army doctrine sets an ideal fighting load of about 30% of body weight for conditioned soldiers.7

Real hikers often exceed 20%. Appalachian Trail backpackers in Boulware's study carried 25.0% (men) and 27.9% (women) of body weight on average.8 The practical takeaway: lighter is easier on the body, and 20% is a sensible target, but it is not a line where a load becomes safe or unsafe.

The Ten Essentials, according to NPS

The National Park Service describes the Ten Essentials as items that help with minor injuries, sudden weather changes or unexpected emergencies.3 NPS advises starting with a pre-made first-aid kit and adapting it to the trip and your own medical needs, recommends headlamps because they are hands-free, and notes that bright clothing makes you easier for search and rescue to see.3

The list also includes a habit that weighs nothing: tell someone where you are going and when you expect to be back.3 NPS separately advises not relying on a cell phone for emergencies and considering a personal locator beacon.9 Some guides say short hikes account for most rescue calls; no search-and-rescue statistics are in this site's library, so treat that as a general caution rather than a measured figure.

Getting the hydration line right

The hydration category lists a filter or tablets for refills, and the difference between them matters. CDC says most portable filters remove parasites but not viruses or bacteria, that chlorine bleach and iodine don't work well against parasites, and that filtering first before chemical treatment is the fix.4 Filter ratings vary, so check what yours removes. Boiling is the most reliable method CDC lists: 1 minute for clear water, 3 minutes above 6,500 feet.4

Pack placement matters once the list is loaded. The Appalachian Mountain Club puts sleeping gear at the bottom and dense items like food, cook gear and water about two-thirds up the main compartment, centered against the back.10
