Result: Select all options above.
Use #1 — Extended Hiking Trips
Longer hiking trips require more food, more clothing, more equipment, additional safety supplies, larger sleeping systems, and more contingency gear. REI’s backpack guidance places 50–80L packs in the multiday range and 70L+ in the extended-trip range.
Use #2 — Multi-Day Camping

- Minimal extra layers
❄️ Cold Weather
- 🧥 More insulation
- 🧤 Gloves

REI notes that winter trips can require larger packs because warmer sleeping bags, extra clothing and larger shelters can take up additional space.
Use #4 — Remote Trips With Limited Resupply
The farther you travel from resupply opportunities, the more important it becomes to plan your food, water and essential equipment carefully.
The National Park Service recommends considering route conditions, water availability and trip requirements when preparing for backpacking trips.
Use #5 — Carrying More Food
Use #6 — Carrying Group Equipment
An 80L backpack can provide useful additional room when one person is responsible for carrying shared equipment.

Use #8 — Long Trips With More Clothing
Use #9 — Extended Mountain Adventures
Use #10 — Long Wilderness Camping

An 80L backpack can be useful when carrying shared cooking equipment, shared shelter components, extra food, group repair supplies, and common safety equipment.
