Why Choose a 70L Backpack?
70L Backpack for Hiking
Hiking requirements change based on distance, duration, weather, terrain, camping equipment, food, and water availability.
When Is 70L Useful for Hiking?
- ✅ Hiking for several days
- ✅ Carrying your own shelter
- ✅ Carrying a sleeping system
- ✅ Carrying several days of food
- ✅ Carrying bulky clothing
- ✅ Traveling through variable weather
A lightweight hiker with compact equipment may need significantly less space.
70L Backpack for Camping
Camping is where extra volume becomes especially useful because shelter, sleeping and cooking systems take up space.
What Can You Fit in a 70L Camping Backpack?
🏕 Shelter
Tent, poles, stakes
🛏 Sleep
Sleeping bag, pad, small pillow
🍳 Cooking
Stove, cookware, utensils
🍚 Food
Meals, snacks, drinks
👕 Clothing
Base layer, warm layer, rain protection, extra socks
🧴 Personal
Toiletries, electronics, small essentials
70L Backpack for Extended Adventures
Extended trips may require carrying more supplies because of longer duration, limited resupply, variable weather, larger gear requirements, additional food, and additional clothing. REI identifies 70L+ packs as suitable for extended trips of 5+ nights and notes their usefulness for colder trips where sleeping bags, clothing and four-season shelters can be bulkier.
Extended Trip Packing Strategy
70L for Cold-Weather Adventures
☀️ Summer
Light layers, compact gear
🍂 Fall
Additional layers, weather protection
❄️ Winter
🧥 Extra layers, 🛏 Larger sleep system, 🏕 More substantial shelter, 🌧 Additional weather protection
REI notes that larger packs can accommodate extra clothing, warmer sleeping bags and four-season tents more comfortably on winter trips.
What Should Go Inside a 70L Backpack?
70L Backpack Weight vs Capacity
Capacity ≠ weight. A 70L backpack can hold more, but that doesn’t mean it should be loaded to maximum capacity.
Fit Matters More Than “70L”
REI emphasizes that torso length—not overall height—is the key measurement for backpack sizing, and that hipbelt fit is important because much of the load should be supported around the hips.
Hiking vs Camping vs Extended Adventures
70L vs 60L
✅ 60L Better If:
- Gear is compact
- You pack efficiently
- Trip is shorter
- You want less unused capacity
✅ 70L Better If:
- Gear is bulkier
- Camping equipment takes more space
- Trip is longer
- You need more food/clothing
70L vs 80L
Choose the capacity that fits your actual equipment rather than buying the largest available option.

Yes, it can provide useful room for a tent, sleeping system, food and cooking equipment, depending on how bulky your gear is.
