What methods are there for determining the correct length of backpack?
White Mountain recommends two methods of determining the correct backpack length. In the first method, you can hold the backpack up to the individual with the hip belt level with the Iliac Crest (more commonly known as the Hipbone). If the backpack does not proceed past shoulder height by more than 5 cm, or not lower than the shoulder height by 10 cm, then this is a suitably sized backpack for that individual. The second method is to Measure your Torso Length, and compare this measurement to the recommended Torso Length for each backpack provided by the backpack supplier, if available. All credible backpack suppliers will list the recommended Torso Length for each of their Internal Frame Backpacks with information supplied on each of these products.
