An internal backpack is a type of backpack characterized by having its support frame built inside the pack itself, making it distinct from external frame backpacks. This design has a significant impact on comfort, weight distribution, and overall performance, especially when used for activities like hiking.
Key Features of Internal Frame Backpacks
| Feature | Description | Benefits | Potential Drawbacks |
|---|---|---|---|
| Frame Location | The supporting frame is integrated within the backpack's main body. | Enables a closer fit to the wearer's back. | Can reduce ventilation, causing more back sweat. |
| Weight Distribution | Transfers the weight of the load closer to the wearer’s center of gravity. | Improves balance and stability, particularly on uneven terrain and for strenuous activities such as long hikes. | Can sometimes make it more difficult to organize gear efficiently, depending on the pack's design. |
| Comfort | Molds closely to the wearer’s body. | Generally more comfortable for long hikes and extended wear. Allows for greater freedom of movement. | The close fit may restrict air flow, potentially making the back hotter. |
| Weight | Often lighter compared to external frame backpacks. | Makes the pack easier to carry, especially for long distances. | Can sometimes sacrifice durability compared to some external frame backpacks. |
| Ventilation | Generally has less space between the pack and the back for airflow. | Offers a streamlined profile, reducing snags and making it easier to maneuver in confined areas. | Can sometimes lack ventilation, leading to a hotter back and greater sweating. |
| Gear Access | Can sometimes have more limited access to specific gear sections. | Streamlined design often makes packing and unpacking more efficient overall. | May require more unpacking to reach items stored at the bottom of the pack. |
Advantages of Using Internal Frame Backpacks
- Enhanced Balance: The way the internal frame distributes weight results in improved balance while hiking.
- Improved Mobility: They are designed to move with the body, making them suitable for navigating challenging paths and terrains.
- Lighter Weight: The absence of an external frame contributes to a lighter overall pack weight.
- Closer Fit: It will generally mold to your body, giving greater comfort, especially during long hikes.
- Streamlined Design: Less prone to snagging and easier to carry.
Considerations When Choosing an Internal Frame Backpack
- Ventilation: Look for models that feature back panel designs that promote airflow.
- Organization: Consider models with well-placed pockets and compartments, if easy gear access is important.
- Fit: Always try the backpack with weight to ensure it is a proper fit.
- Durability: Make sure it can withstand the type of use you intend to give it.
In summary, internal backpacks are a great choice for activities that demand mobility, balance, and extended wear-time. They have been favored for long hikes due to their comfort and better load distribution. While they can have some ventilation challenges, many modern internal backpacks address this issue with breathable materials and designs.
