By Lauren HollandA solid rei backpacking gear list starts with knowing what you actually need, what you can leave behind, and how much everything weighs together. This guide walks you through building that list from the ground up, using base weight math and category checklists so you finish with a packing plan you can trust on the trail.
Why Start With a Base Weight Target
Base weight is the total weight of your pack with everything except food, water and fuel. Tracking it is the fastest way to see where your gear is heavy and where you can cut. Most people find that three or four items make up half their total load, so a base weight target gives you a clear number to work against.
Common targets look like this. Traditional backpackers often land between 25 and 35 pounds base weight. Lightweight hikers commonly aim for 15 to 20 pounds, and ultralight packers often target 10 pounds or less. Pick a target that fits your comfort, your trip length and your fitness, then build toward it.
Step 1: Define Your Trip Parameters
Before you touch a single item, write down the conditions you expect. Gear that works for a two-night summer trip in a desert is not the same as gear for a five-night autumn trip in alpine terrain.
- Trip length in nights and total miles
- Expected overnight low temperatures
- Likelihood of rain, snow or wind
- Water sources and how far apart they are
- Whether you will sleep in established campsites or stealth sites
- Bear country or other wildlife storage rules
Write these down on one page. Every gear decision should trace back to one of these lines.
Step 2: Build the Big Three
The big three are your pack, shelter and sleep system. Together they usually account for the largest share of your base weight, so spend your planning time here first.
Backpack
Match pack volume and weight to your load. A pack rated for 50 to 60 liters suits many multi-night trips, while lighter loads can use a 35 to 45 liter pack. Check the frame style and maximum recommended load, which manufacturers specify on most packs. Carrying more weight than a pack is designed for usually causes discomfort and poor fit.
Shelter
Choose between a tent, a tarp or a hammock based on your terrain and tolerance for bugs and weather. Freestanding tents add weight but give you a dry, bug-free space in most conditions. Tarps and hammocks save weight but require more skill to pitch in exposed or buggy areas. Check the packed weight and the floor and fly fabric listed by the manufacturer, and factor in stakes and guylines.
Sleep System
Your sleep system is the sleeping bag or quilt, the sleeping pad and any liner. Look at the temperature rating and whether it is a comfort or limit rating, since manufacturers specify both. Pair an insulated pad with an R-value appropriate for the coldest ground temperature you expect. Down insulation compresses well but loses loft when wet, while synthetic insulation keeps some warmth when damp.
Step 3: Work Through the Remaining Categories
Once the big three are set, move through the rest of your kit by category. Keep each category in its own stuff sack or packing cube so you can find items quickly and keep weight visible.
Clothing
- One base layer for sleeping, kept dry
- One hiking shirt and one hiking pant or shorts
- A warm insulated layer such as a puffy jacket
- A waterproof shell jacket
- Hat, gloves and warm socks in colder conditions
- Extra socks, typically one pair per two to three days
Cooking and Water
Cooking gear includes a stove, fuel, a pot, a lighter, a spork and a windscreen if needed. Water gear includes a filter or purification method, bottles or a bladder, and a container for carrying extra water between sources. Plan your fuel by estimating roughly how many boils per day you need, then add a margin.
Navigation and Safety
- Paper map and compass, or an offline map on a phone with a backup battery
- Headlamp with spare batteries
- First aid kit sized to your group and trip length
- Knife or multi-tool
- Emergency communication device if you travel where cell service is unreliable
- Fire starter and a means to make a fire where permitted
Toiletries and Miscellaneous
Keep this category minimal. Pack a small amount of sunscreen, insect repellent, a small towel or bandana, a trowel for catholes, toilet paper, hand sanitizer and any personal medication. Store repellent and sunscreen in sealed bags so they do not contaminate food or gear.
Step 4: Run the Math
Weigh every item on a kitchen or digital scale in grams, then add everything up. Sort items into worn weight, pack weight and consumables. The table below shows a simple way to organize the numbers for a three-night trip.
| Category | Example Items | Weight Notes |
|---|---|---|
| Big three | Pack, shelter, sleep system | Usually the largest share of base weight |
| Clothing (worn) | Shirt, pants, shoes | Track separately from pack weight |
| Clothing (packed) | Puffy, shell, spare layers | Count in base weight |
| Kitchen and water | Stove, pot, filter | Fuel and water counted separately |
| Safety and navigation | First aid, headlamp, map | Keep essentials, trim extras |
| Consumables | Food, fuel, water | Excluded from base weight |
Once you have totals, compare them to your base weight target. If you are over, look first at the big three, then at anything you have not used on past trips, then at duplicate items.
Step 5: Pack and Test
Pack your gear in the order you will need it. Heavy items go close to your back and centered between your shoulder blades and hips. Keep rain gear, headlamp and first aid in the top lid or an outer pocket. Pack the bag, walk around with it for at least 20 minutes, and adjust the load lifters and hip belt until the weight sits on your hips.
A short overnight test at a nearby trail is a good way to find problems before a longer trip. You will quickly learn whether a sleeping pad is too cold, a stove is too slow or a pack strap digs into your shoulder.
Common Mistakes
- Building the list around a single trip you may never take again
- Packing for worst-case weather in every season
- Carrying multiple versions of the same item, such as two headlamps or three knives
- Ignoring consumables, which can add several pounds to a multi-day load
- Skipping a test hike, then discovering fit or comfort problems on the trail
- Choosing a sleeping bag by comfort rating alone instead of checking the limit rating
Tips for Using Your Gear List Over Time
- Keep a master list on paper or in a spreadsheet and update it after every trip
- Note items you never used and remove them from the next list
- Store a packed-and-ready bin so you only need to add food and fuel before leaving
- Review your list each season, since clothing needs change with temperatures

Recommended gear
A pack with a supportive frame and a hip belt that fits your torso length will make the biggest difference in comfort, so check fit first. A lightweight stove system gives you reliable boils with less fuel to carry. A dry bag or pack liner protects your sleep system if rain hits, which can ruin down insulation. Packing cubes keep categories separated and make it easy to check what you have packed.

FAQ
What is a good base weight for a beginner backpacker?
Many beginners find a base weight between 20 and 30 pounds comfortable for multi-night trips. Lower targets are possible with experience, but comfort and safety should come first.
Should I include food and water in my gear list?
List them separately. Food, water and fuel are consumables that change through a trip, so they are excluded from base weight but still need planning.
How do I know if my pack is the right size?
Pack volume should match your gear with a little room to spare. Check the manufacturer’s maximum recommended load and try the pack with a realistic weight before committing.
How often should I update my gear list?
Update it after every trip and review it at the start of each season, since temperatures, trip lengths and personal needs change.
Do I need a separate list for each season?
Many hikers keep one core list and add or subtract clothing and sleep items for each season. This keeps the base list simple.
What should I do if my gear list is too heavy?
Start with the big three, then remove duplicates and unused items. If you still need to cut weight, consider lighter alternatives in the heaviest categories. Consult an experienced guide or outdoor instructor if you are unsure how to safely reduce weight for a longer or more remote trip.
Is a printed gear list still useful?
Yes. A printed or laminated checklist is easy to use at the trailhead and does not depend on battery life or signal.
Conclusion
A reliable rei backpacking gear list comes from a clear trip plan, a base weight target and a category-by-category review. Start with the big three, weigh everything, and test your setup on a short trip before going farther. Update the list after each outing and it will get more accurate every season.
