What we mean by this category
A backpack is a load-carrying system rated by capacity (liters), suspension type (internal or external frame), and torso-length fit. Overnight backpacks range from 30 to 85 L.
Who this equipment is for
Day hikers, backpackers, thru-hikers, canoeists (portage), and hunters carrying game.
Important buying criteria
- Capacity (L)
20–30 L day; 45–55 L overnight; 55–70 L week; 70–85 L expedition or family gear.
- Frame
Internal for load compression and body contact; external for airflow and heavy irregular loads (e.g., firewood, game meat).
- Torso length
Measured from C7 vertebra to iliac crest. Fit torso first, hip belt second.
- Fabric
Ripstop nylon (210–420D) for balance; Dyneema for weight; canvas for classic bushcraft loads.

Material or technology comparison
| Fabric | Weight | Durability | Waterproof | Cost |
|---|---|---|---|---|
| 210D ripstop nylon | Light | Fair | Fair | $ |

Climate and season considerations
In wet climates, prefer waterproof fabrics or plan on a pack liner. In hot climates, look for a suspension with airflow, or you'll sweat through any pack.
Size, fit, or capacity guidance
Hip belt carries 80% of a well-fitted load. Torso must match spine length — women's-specific packs are usually shorter, not narrower.

Frequently asked buying questions
- What size for a first backpacking trip?
- 50–55 L. Smaller forces gear compromises before you know what you need; larger tempts you to over-pack.
- Are ultralight packs worth it?
- For thru-hikers, yes. For weekend backpackers, a 3-lb pack with real load transfer is often more comfortable.
