How is the calorie estimate calculated?
Packstack combines your body stats (weight, height, age, sex, body type) with your trip details (distance, elevation gain, terrain, pace, temperature, and pack weight) to estimate your daily calorie burn, food weight, and water needs.
What's the difference between base weight, worn weight, and consumables?
Base weight is everything in your pack excluding food, water, and fuel. Worn weight covers items you wear or carry on your body, like shoes and trekking poles. Consumables are things you use up along the way. Packstack tracks all three separately so you know exactly what you're hauling.
