How to Choose the Best 70L Hiking Backpack

Don’t choose a backpack just because it says 70L. Learn how to compare fit, comfort, capacity, features and construction so you can choose a pack that actually suits your trips.

Need the Answer Fast?

The best 70L hiking backpack is not necessarily the one with the most features. Look for one that:

1. Fits your torso length
2. Has a comfortable hip belt
3. Can carry your realistic gear volume
4. Has an appropriate frame and suspension
5. Isn’t unnecessarily heavy
6. Provides the organization you actually use
7. Matches your hiking and camping conditions
8. Can be adjusted properly
If a 70L pack fits your body well and comfortably carries your actual equipment, you’re already much closer to the right choice than someone who simply picked the backpack with the biggest feature list.

Choose Your Pack β€” Quick Quiz

What type of trip do you usually take?
How bulky is your equipment?
Do you carry camping equipment?
What conditions do you usually encounter?
What matters most?

Your priority should be: Select all options above.

Start With Your Trip, Not the Backpack

Before looking at backpack features, ask:

How many days are you normally away?
Do you camp?
How much food do you carry?
Do you need bulky clothing?
Do you carry shared equipment?
How often can you resupply?
What season do you hike in?

Washington Trails Association recommends identifying what equipment you actually need before buying a backpack and notes that 50–70L can suit many 3–7-night trips, while colder conditions or bulkier equipment can change the requirement.

What Does “70L” Actually Tell You?

70L describes volume, not weight. 70L = capacity, not carrying weight or comfort.

Capacity β€” How much space
Carrying Weight β€” How heavy your load becomes
Fit β€” How the pack matches your body

The Most Important Factor β€” Backpack Fit

REI states that torso lengthβ€”not heightβ€”is the key measurement for backpack sizing, and hip-belt fit is also important because much of the load should be supported around the hips.

Torso Length β€” C7 to hip bones
Hip Circumference β€” Hip-belt sizing
Adjustable Torso β€” Fine-tune fit
Shoulder Straps β€” No excessive load
Sternum Strap β€” Shoulder harness position
Load Lifters β€” Upper load control

Choose the Right Frame

πŸ—οΈ Internal Frame

Support, stability, load transfer, common backpacking use

⚑ Lightweight Frame

Lower overall pack weight, less structure, best when loads are controlled

πŸ”§ Adjustable Suspension

Greater fitting flexibility, useful for different torso lengths

Backpack Weight Matters

PACK
+ GEAR
+ FOOD
+ WATER
= TOTAL LOAD
Don’t sacrifice basic fit and support simply to save a small amount of empty-pack weight.

Suspension and Load Support

Hip Belt β€” Transfers load to hips
Shoulder Harness β€” Positions the pack
Load Lifters β€” Upper load control
Sternum Strap β€” Stabilizes harness

How Much Structure Do You Need?

Lighter Construction β€” Lower pack weight, controlled loads
More Supportive Construction β€” Substantial equipment and supplies

Choose the construction according to the load you actually expect to carryβ€”not the load you imagine you might carry someday.

Check the Main Compartment Design

πŸ” Top Loading β€” Traditional and simple
πŸ“‚ Front Access β€” Easier to reach deep items
πŸ”“ Multiple Access Points β€” Unpack less to reach gear

Pockets and Organization

Side Pockets β€” Water bottles or long equipment
Hipbelt Pockets β€” Small frequently used items
Top Lid β€” Quick-access equipment
Front Stash β€” Lightweight layers or frequently accessed items
Sleeping Bag Compartment β€” Dedicated lower access
Attachment Points β€” External equipment

REI highlights features such as side pockets, hipbelt pockets, top-lid compartments, sleeping-bag compartments and attachment points as factors to consider.

Don’t Buy More Pockets Than You Need

More pockets aren’t automatically better. Every extra compartment can add complexity and sometimes weight.

Compression Straps β€” Why They Matter

Full pack β†’ compression β†’ more stable load
Partially filled backpacks
Stabilizing equipment
Reducing unnecessary movement
Securing external equipment

Hydration Features

Hydration reservoir sleeve
Hose routing
Bottle pockets
Easy-access water storage

REI notes that many backpacking packs include an internal hydration-reservoir sleeve and ports for routing the tube.

Weather Protection

🌧 Built-in rain cover
πŸ’§ Internal waterproof liners/stuff sacks

REI notes that pack fabrics can absorb water and that rain can enter through seams and zippers. If your trip includes unpredictable weather, think about how you’ll protect the contents, not just the outside of the backpack.

Materials and Durability

Fabric type
Stitching
Zippers
Buckles
Reinforced stress points
Bottom-panel construction
Abrasion resistance

Durability depends on material, construction, stitching, treatment and how the backpack is used.

Comfort Features Worth Paying Attention To

πŸ› Padded Hip Belt

Comfort and load transfer

🌬 Back Ventilation

Improves airflow

🎯 Contoured Shoulder Straps

Improves comfort

πŸ”§ Adjustable Suspension

Improves fit flexibility

⬆ Load Lifters

Improves upper pack control

Comfort comes from the combination of design + correct sizing + correct adjustment.

70L vs 80L β€” Should You Go Larger?

βœ… Choose 70L if:

  • You don’t routinely carry very bulky gear

βœ… Consider 80L if:

  • Your equipment regularly exceeds 70L
  • You carry substantial shared gear
  • Cold-weather equipment is bulky
  • You need significantly more supplies

Features You Shouldn’t Pay Extra For Unless You Need Them

Extra compartments
Removable accessories
Complicated suspension systems
Unused attachment points
Features designed for activities they don’t do

A feature is valuable when it solves your problem.

How to Test a 70L Backpack Before Buying

  1. Test 1 β€” Load It: Use a realistic load
  2. Test 2 β€” Adjust the Torso: Set the suspension correctly
  3. Test 3 β€” Check Hip Belt: Should sit comfortably
  4. Test 4 β€” Check Shoulder Straps: Natural fit
  5. Test 5 β€” Walk: Walk around with the loaded pack
  6. Test 6 β€” Bend: Check for excessive movement
  7. Test 7 β€” Access Gear: Try reaching frequently used items

REI recommends testing pack fit with a representative load and making adjustments to the hipbelt, shoulder straps, load lifters and sternum strap.

Interactive FAQs

What is the most important thing when choosing a 70L backpack?

Fit should be one of your first priorities, especially torso length and hip-belt sizing.

Is a 70L backpack good for multi-day hiking?

It can be, particularly when the trip requires substantial equipment or supplies. WTA lists 50–70L as a common range for 3–7-night trips.

How do I know what backpack size fits me?

Check your torso length and hip circumference against the manufacturer’s sizing chart. Pack sizes vary between brands and models.

Is 70L too big for hiking?

Not necessarily. It can be appropriate for multi-day or gear-heavy trips, but it may be unnecessarily large for compact setups.

Should I choose a lightweight or heavy-duty 70L pack?

Choose based on your actual load and the conditions you’ll encounter. Don’t choose extra structure simply because it sounds stronger.

What features should a 70L backpack have?

Prioritize the features that match your needs: appropriate suspension, useful pockets, compression, hydration compatibility, weather protection and suitable attachment points.

Is a 70L backpack better than a 60L backpack?

Only if you genuinely need the additional capacity.

Is 80L better than 70L?

Not automatically. Larger capacity is useful only when your gear requires it.

Should I test a backpack before buying?

If possible, yes. Testing it with a realistic load gives you a much better idea of fit and comfort than trying it empty.
