Best Uses for a 70L Hiking Backpack on Outdoor Trips
From multi-day hikes to camping and extended outdoor adventures, discover where a 70L backpack makes sense—and when a smaller pack may be the smarter choice.
What Is a 70L Backpack Best Used For?
A 70L backpack is particularly useful when you need to carry a relatively high volume of outdoor equipment, such as shelter, sleeping system, clothing, food, cooking equipment, water, personal gear, and weather protection.

Why 70L Is a Useful Middle Ground
This gives it a useful position for people who need more room than a compact multiday setup but don’t necessarily need a very large expedition-style pack.
Best Use #1 — Multi-Day Hiking
Multi-day hiking can require: tent, sleeping bag, sleeping pad, food, clothing, water, cooking gear, and personal equipment. REI includes 50–80L packs in its multiday category, making 70L a reasonable capacity to consider for substantial multiday setups.
Best Use #2 — Camping Trips
70L becomes especially useful when you’re carrying your own shelter and complete camping setup.
Best Use #3 — Extended Hiking Trips
Best Use #4 — Trekking Adventures
Best Use #5 — Cold-Weather Outdoor Trips
☀️ Warm Weather
Light clothing, compact sleeping system
❄️ Cold Weather
- 🧥 Insulation
- 🧤 Gloves
- 🧣 Additional layers
- 🛏 Warmer sleeping system
- 🌧 Weather protection
REI notes that winter conditions can require additional pack volume because colder-weather sleeping systems, clothing and shelters can be bulkier.
A 70L pack may be useful in cold conditions even when a smaller pack works perfectly well during summer.
Best Use #6 — Remote Wilderness Trips
The less access you have to resupply, the more important available pack volume can become.
Best Use #7 — Trips With Limited Resupply
If you can’t restock food or other essentials, you may need to carry more from the beginning. Additional space for supplies is an advantage, but more supplies also mean more weight.
Best Use #8 — Carrying Shared Group Equipment
Your backpack capacity should account for everything you personally carry—not just your own clothing.
Best Use #9 — Photography + Outdoor Adventures
Extra gear = extra weight. Extra capacity can help accommodate bulky non-standard equipment.
Best Use #10 — Outdoor Travel + Hiking
A 70L pack may be useful when one trip combines different activities and the user needs to carry both travel and outdoor equipment. However, a hiking backpack isn’t automatically the best choice for every type of travel. Consider access, organization and airline baggage requirements separately.
Best Use #11 — Backpacking With Bulky Gear
Examples: bulky sleeping bag, large shelter, thick clothing, larger cooking system, shared equipment.
Best Use #12 — Beginner Multi-Day Camping
Beginners often carry more equipment because they’re still learning what they actually use. A 70L backpack can provide some additional flexibility. Don’t use the extra space as permission to pack everything you own.
When 70L Is NOT the Best Choice
70L vs 60L for Different Outdoor Activities

70L vs 80L — When Do You Need More?
The Most Important Factor Isn’t the Trip Name
Trip requirements → Gear volume → Backpack capacity
How to Quickly Decide If You Need 70L
- Lay out your complete gear
- Separate it into: Shelter, Sleep, Clothing, Food, Cooking, Water, Essentials
- Try packing it into your current backpack
- If essential items don’t fit comfortably, consider more capacity
- If everything fits with significant empty space, don’t automatically size up
