Gear to Consider

Base Weight vs Total Pack Weight: What Counts

Base weight is the weight of your pack without consumables (food, water, fuel). It represents your equipment investment and is the weight backpackers use to categorize their kit.

Total pack weight is base weight + consumables. This is what you actually carry on day one. For a 3-day trip at 2 lbs/day food: add 6 lbs food + 1 lb fuel + water at trailhead.

Worn weight (boots, clothes, trekking poles) is not included in base weight by convention but is still on your body and counts for fatigue purposes.

Recommended Gear

The Big Three (shelter, sleep system, pack) account for 60–70% of your base weight. Upgrading these first delivers the biggest weight reduction per dollar spent.
