SIZE GUIDE

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 usefulβ€”or simply extra space.

The 10-Second Answer

βœ… 80L probably isn’t too big if: Bulky gear, extended trips, substantial food, limited resupply, shared equipment 🟑 80L may be too large if: Day hikes, compact gear, short trips, frequent resupply, mostly empty pack
The correct size is determined by your equipment volumeβ€”not the number printed on the backpack.

Is My 80L Too Big? β€” Quick Quiz

How long is your typical trip?
Do you camp overnight?
Is your sleeping gear bulky?
Do you carry cooking equipment?
Do you carry several days of food?
Do you hike in cold conditions?
Can you resupply during the trip?

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 β€” 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.

πŸ₯Ύ Hiker A

  • Compact sleeping system
  • Lightweight shelter
  • Minimal clothing

πŸ₯Ύ Hiker B

  • Bulky sleeping bag
  • Larger tent
  • Cooking equipment
  • Extra clothing

Same trip. Different volume.

When an 80L Backpack Is NOT Too Big

πŸ• Extended Camping

Shelter, sleeping equipment, cooking gear, clothing

πŸ₯Ύ 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

πŸ• Shared Group Equipment

Tent, cooking equipment, group gear

When 80L Probably IS Too Big

Day Hiking β€” You generally don’t need an 80L pack
Short Minimalist Trips β€” Compact equipment fits in smaller pack
Frequent Resupply β€” You don’t need to carry everything at once
Warm-Weather Trips β€” Clothing and sleeping equipment may take less space
Lightweight Equipment β€” Modern compact gear can significantly reduce volume
Experienced Minimalist Packing β€” Efficient packing can reduce capacity needed

80L vs 60L β€” Which Is Actually Better?

80L vs 70L β€” 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

80L AVAILABLE SPACE

Unused space isn’t automatically wasted space. But if you’re regularly carrying an almost-empty 80L backpack, a smaller pack may be more practical.

The Overpacking Problem

Bigger bag
↓ More empty space
↓ “I might as well take this.”
↓ More equipment
↓ More weight
↓ Less comfortable hiking

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?

βœ… Correct β€” Backpack sits close to the body
❌ Problematic β€” Pack extends unnecessarily far away

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

β˜€οΈ 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

1 Day β€” Small food requirement 3 Days β€” Moderate 5 Days β€” Larger Extended β€” Potentially substantial

Water Is Different From Backpack Capacity

Water is primarily a weight and availability issue, although containers occupy space.

Is water available along the route?
Can it be treated?
Are there official restrictions?
How remote is the trail?

Resupply Can Make 80L Unnecessary

❌ No Resupply β€” Large load carried at once
βœ… With Resupply β€” Smaller carried load

5 Signs Your 80L Is Actually Too Big

Sign #1: You consistently use less than half of its capacity
Sign #2: You carry items simply because there’s room
Sign #3: Your pack feels unnecessarily bulky on shorter trips
Sign #4: A smaller pack would hold everything you actually need
Sign #5: You bought 80L for hypothetical trips you rarely take

5 Signs Your 80L Is NOT Too Big

Sign #1: Your gear consistently fills a smaller pack
Sign #2: You regularly carry bulky camping equipment
Sign #3: You need several days of food
Sign #4: Your trips involve cold-weather equipment
Sign #5: You carry shared group equipment

How to Choose a Smaller Backpack If 80L Is Too Big

Capacity β€” Does it actually fit your equipment?
Fit β€” Does it sit comfortably?
Suspension β€” Is it appropriate for your intended load?
Organization β€” Can you access equipment efficiently?
Accessibility β€” Can you reach important items without unpacking?
Durability β€” Does it match your expected environment?
Weather protection β€” Can you protect your equipment from moisture?
