Is an 80L Hiking Backpack Too Big for Your Trip?
Is 80L more than you actually need? Before buying a large hiking backpack, compare your trip, gear and packing style to find out whether 80L is genuinely useful—or simply extra space.
The 10-Second Answer
Is My 80L Too Big? — Quick Quiz
Result: Select all options above.
What Does “Too Big” Actually Mean?
1️⃣ Too Much Capacity
You don’t need the available space
2️⃣ Too Physically Large
The backpack’s dimensions interfere with movement or organization
3️⃣ Too Heavy
The backpack and its contents become unnecessarily heavy
These are not the same problem. A backpack can have 80L capacity without automatically being too heavy.
The Biggest Question — How Much Gear Do You Actually Carry?
Two people can take the same five-day hiking trip and need completely different backpack capacities because equipment differs.
🥾 Hiker A
- Compact sleeping system
- Lightweight shelter
- Minimal clothing
🥾 Hiker B
- Bulky sleeping bag
- Larger tent
- Cooking equipment
- Extra clothing
Same trip. Different volume.
When an 80L Backpack Is NOT Too Big
🏕 Extended Camping
Shelter, sleeping equipment, cooking gear, clothing
🥾 Multi-Day Hiking
More days mean more food, clothing and equipment
❄️ Cold-Weather Trips
Cold-weather gear can be bulky
🍚 Limited Resupply
Several days of food and supplies require volume
🏕 Shared Group Equipment
Tent, cooking equipment, group gear
When 80L Probably IS Too Big
80L vs 60L — Which Is Actually Better?
80L vs 70L — The Middle Ground
70L can be a useful middle ground for people whose equipment volume falls between those categories.
80L Doesn’t Mean You Should Fill 80L
The Overpacking Problem
Is the Backpack Itself Too Heavy?
Separate pack capacity from pack weight. Check empty pack weight, suspension system, intended load range, fit, materials, and features.
Is Your 80L Backpack Physically Too Large?
Fit and load distribution matter. REI’s backpack-fitting guidance explains how the hip belt, shoulder straps and suspension system contribute to proper fit.
How Weather Changes Whether 80L Is Too Big
☀️ Warm
Potentially less bulky equipment
🌧 Wet
More weather protection and dry storage
❄️ Cold
Bulky insulation and sleeping equipment
Before deciding, check the National Weather Service forecast for your destination.
Food Can Change the Equation
Water Is Different From Backpack Capacity
Water is primarily a weight and availability issue, although containers occupy space.
