Start With Your Trip, Not the Backpack
Before looking at backpack features, ask:
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.
The Most Important Factor — Backpack Fit
REI states that torso length—not height—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.
Interactive Torso-Fit
Choose the Right Frame
🏗️ Internal Frame
Support, stability, load transfer, common backpacking use
⚡ Lightweight Frame
Lower overall pack weight, less structure, best when loads are controlled
🔧 Adjustable Suspension
Greater fitting flexibility, useful for different torso lengths
Backpack Weight Matters
Suspension and Load Support
How Much Structure Do You Need?
Choose the construction according to the load you actually expect to carry—not the load you imagine you might carry someday.
Check the Main Compartment Design
Pockets and Organization
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 — Why They Matter
Hydration Features
REI notes that many backpacking packs include an internal hydration-reservoir sleeve and ports for routing the tube.
Weather Protection
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
Durability depends on material, construction, stitching, treatment and how the backpack is used.
Comfort Features Worth Paying Attention To
🛏 Padded Hip Belt
Comfort and load transfer
🌬 Back Ventilation
Improves airflow
🎯 Contoured Shoulder Straps
Improves comfort
🔧 Adjustable Suspension
Improves fit flexibility
⬆ Load Lifters
Improves upper pack control
Comfort comes from the combination of design + correct sizing + correct adjustment.

Common Mistakes When Buying a 70L Backpack
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.
