A critical design decision for hunters: Should I use an internal or external frame hunting backpack? Frame type impacts load capacity, comfort, mobility, and terrain suitability. At GAF Outdoor, a Guangzhou-based hunting gear manufacturer since 2011, we design both frame systems. This guide compares engineering, performance, and use cases with factory data.
