According to him, your correct frame size can be found by measuring your torso from the seventh vertebra down the spine to the point in the small of your back which is horizontally level with the top of your hip bones. To find this point, use your fingers to trace the hip bone upwards till you feel the point where the top edge of your hip bones curve inwards, on the side of the hip, creating something of a shelf. This measurement is the torso length, especially useful to consider those packs with non-adjustable back system. In fact this system that is used throughout the outdoor industry today to measure the exact body size and to determine the correct frame's size.
Next is to choose the correct frame size. Remember every backpack is useless (regardless of your good height and top quality of backpack) unless it has a correct frame size according to your body and shape. Gone were the days when people think 'one-size-fits-all'-it far from the truth. Experts strongly believe that your torso size and your overall height are two completely separate measurements when it comes to backpacks. Actually Wayne Gregory was the first backpack designer who thought seriously about the importance of correct frame size to fit your torso.
Well, it's not only the US defense troops that can benefit from using solar powered backpacks. People, and not just followers of green living, are finding it increasingly convenient to use them. Solar backpacks are made to serve the same function as a regular backpack, with the additional convenience of being a source of power for portable electronic appliances. The backpack is equipped with a solar panel which harnesses the natural resource of sunlight, and converts it into reusable energy. In the high tech gizmo world today, staying connected ALL the time is the one thing most people cannot do without, and a solar powered backpack offers you a way out.
Because backpacks are so useful and versatile and have been around for such a long time, you are going to find a variety of options for you to choose from. Because like pretty much any item that has been around for a long time, the backpack has been modified and improved in different versions and varieties to suit the needs of people today. Because our needs are so diverse, and each person may need a backpack for one reason or another, so too have the backpacks of today become diverse to better match our needs.
First, it is important to note that backpacks can be grouped into four different categories - frameless (your typical backpack for college), external frame (hiking, camping), internal frame (hiking, skiing, sports), and the body pack (overnight camping, long trips). As I mentioned, the frameless style is your best bet for the college lifestyle. These backpacks are usually constructed using synthetic materials and are much cheaper than the other three types.
The human spine is made up of 33 bones called vertebrae, and between the vertebrae are discs that act as shock absorbers. When something heavy-such as a backpack filled with books-is incorrectly placed on your child's shoulders, the force of that extra weight can pull your child backwards. To compensate, your child may bend forward at the hips or arch his or her back, which can cause your child's spine to compress unnaturally. Because of the heavy weight he or she is carrying, your child might begin to develop shoulder, neck, and back pain.
