Types of Back Packs • External Frame • Designed to hold a heavy load. It is stable & rigid for comfort. • The rigidity of the frame allows the weight of the load to be distributed evenly over the body. • Good choice to use for heavy loads over moderate terrain or existing trails due to the height of the load on the pack. • Some keep you cooler because of the space between the pack and the hikers back. • Tends to be less expensive and lighter in weight.
Types of Back Packs • Internal Pack • Ideal for activities such as: mountaineering, skiing, snowshoeing, off-trail hiking, & scrambling over rough terrain. • Is more flexible, rides closer to the body, is more responsive the packers movement but provides less ventilation. • The absence of a frame & lower profile make it more preferable in the heavy brush. • Its lower positioning on the back allows for a lower center of gravity for better balance. • More expensive due to design and construction.
Considerations • Pack should be 30-35 lbs. and should be balanced when packed • Frequently adjust the straps while hiking to maintain comfort (ex. If the hips are sore loosen the waist belt and tighten the shoulder straps or visa versa). • Don’t pull straps too tight and lose sensation in arms • Loosen straps to help remove pack from back. • Help each other when putting on a heavy pack.
Pack Packing • Although packing the backpack may seem like an obvious and simple task it is important to learn this skill and practice it. Campers with poorly packed packs tend to lose things more frequently. In addition, a poorly packed backpack has greater chance of injuring the carrier and will cause discomfort. • Remember C.B.S. – it stands for Conveniently Balanced System.
C.B.S • Convenience – A pack that is organized so that it permits access to its most needed contents & greatly enhances the packer’s efficient use of time and energy. • Balance – A well-balanced pack with properly distributed weight adds to the safety and comfort of the packer. • System – A pack that is organized with efficient and consistent system speeds the process of daily packing and aids in maintaining an accurate inventory of equipment.
