What is the Torso Length?
The definition of the Torso is the upper part of the human body excluding the head and arms. For the purpose of fitting backpacks we further define the Torso Length, as a point along the spine level with the top of the Iliac Crest (more commonly known as the Hipbone), up to the base of the neck or top of the seventh cervical vertebrae (the prominent bone or large knuckle at the base of the neck), or when bending the head backpacks the crease of the neck. To assist in choosing which size/length of backpack is best for you, first Measure your Torso Length (This link will open a new window with instructions and diagram for accurately measuring your own Torso Length). You can either measure your Torso Length in a straight line, or measure your Torso Length along the curve of your spine.
