What Does 70L Actually Mean?
70L means approximately 70 liters of storage volume under the manufacturer’s stated capacity measurement. It does not mean 70 kg of carrying capacity, 70 days of supplies, 70 items, or 70 liters of usable space in every compartment.

How Much Space Does Each Category Need?
Can a 70L Backpack Hold a Tent?
Usually yes, depending on the tent’s packed size. Packed dimensions matter more than the tent’s sleeping capacity.
When planning pack capacity, check the manufacturer’s packed dimensions rather than judging a tent by its floor size alone.

Water Takes Space — But Weight Matters More
High weight + fixed volume — Water availability along the route affects how much water you need to carry at one time.
70L for a 2–3 Day Trip
A 70L pack can be used for shorter trips, but it may be unnecessarily large for hikers with compact equipment. Useful when: bulky camping gear, cold conditions, shared equipment, or extra supplies are involved.
70L for 3–5 Days
REI includes 50–80L packs in its multiday range for trips around 3–5 nights.
70L for 5–7 Days
70L becomes increasingly useful as food increases, clothing increases, resupply becomes less frequent, and equipment becomes bulkier. WTA lists 50–70L as a common range for many 3–7-night trips.
Cold Weather Can Change Everything
☀️ Summer
Compact sleeping system, light clothing
🌦️ Spring/Fall
Additional layers, weather protection
❄️ Winter
Bulky insulation, warmer sleeping system, additional clothing
REI notes that cold-weather trips can require more pack volume because warmer sleeping bags, extra clothing and larger shelters take more space.
How to Make 70L Feel Bigger Without Buying a Bigger Backpack
Compression vs Stuffing
Compression can reduce the volume of soft items but does not magically reduce their weight.
Where Should Everything Go?
REI’s packing guidance recommends placing sleeping gear toward the bottom, heavier items near the spine in the middle and frequently used items in accessible pockets.
Don’t Confuse Volume With Weight
70L Backpack vs 60L Backpack
70L Backpack vs 80L Backpack
If your equipment already fits comfortably in 70L, moving to 80L may simply give you more room to overpack.
How to Know If You’re Running Out of Space
If you’re constantly forcing your backpack closed, the problem may be gear volume—not your packing technique.
