Which type of pack frame is typically used for SAR packs?

Internal frame packs are commonly used for Search and Rescue (SAR) operations due to several key characteristics that enhance their functionality in demanding environments. One of the main advantages of internal frame packs is their close-to-the-body design, which allows for a better center of gravity and improved stability when maneuvering through challenging terrain. This is particularly important in SAR scenarios where individuals may need to navigate steep inclines, dense brush, or uneven surfaces while carrying essential equipment.

Additionally, internal frame packs often feature a streamlined profile, making them less susceptible to snagging on obstacles compared to external frame packs. This design also provides better aerodynamics and weight distribution, allowing SAR teams to maintain endurance over extended periods. The ability to adjust the load and straps for a personalized fit further enhances comfort during prolonged usage.

While external frame packs offer good ventilation and a larger load capacity, they can be bulkier and less stable in certain scenarios. Frame-less packs, while lightweight, do not provide the same level of support for heavier loads which are commonplace in SAR missions. Hybrid packs, combining elements of both designs, can cater to specific needs but do not match the overall effectiveness of internal frame packs for the rigorous demands of search and rescue operations.
