PACK BASE WEIGHT & CRITICAL LOAD LIMITS
[ ] Luggage Scale
[ ] Baseweight Spreadsheet
[ ] 20% Body Weight Target

Luggage Scale: digital, hook or strap style, with a capacity above your loaded pack weight and readings in pounds or ounces.
Baseweight Spreadsheet: any free spreadsheet app. Columns: item, weight, category (carry, sleep, cook, clothing, safety), keep or cut.
20% Body Weight Target: body weight x 0.20.

Never cut safety gear to save ounces. Navigation, light, first aid, rain layer and your emergency kit stay in the pack. Why it matters: these are the items you need when things go wrong.
Do not trade water for weight. Carry enough to reach your next water source, and bring a way to treat water. Check your route for reliable sources before you go, and check current local rules and trail reports from the managing agency.
Test the load before the trip. Do a short loaded walk at home. If your hips, knees or shoulders hurt in 10 minutes, cut weight or adjust the fit before you head out.

Gear types only.

Base-Weight Audit Calculator [anchor: audit-calculator]

Work it out by hand in four lines:

Body weight x 0.20 = your 20% Body Weight Target. Example: a 150 lb hiker x 0.20 = 30 lb target.
Add up every item in your Baseweight Spreadsheet = base weight.
Base weight + food + water + fuel = total pack weight.
Total pack weight minus your target = how much to cut (if it is above zero).

Why it matters: an overloaded pack changes your balance and wears you out early, and tired hikers make more mistakes. The 20% figure is Wild Dirt's starting target for beginners. If you have back, knee or other health concerns, talk to a doctor and aim lower.

Required gear (like bear-resistant food storage) varies by park and area. Check current local rules with the managing agency before you cut anything: nps.gov, fs.usda.gov or your state park website.

Ounces become pounds, and pounds become sore feet. Weigh it, trim it and go farther. Built by explorers, for the trail.

Know the terms

Base weight: everything in your pack except food, water and fuel
