• There are 3 different sizes/lengths: S (strap length of 1.10 cm), M (1.15 cm) and L (1.18 cm). The length of the cord is measured from where it comes out of the closure nozzle, once it is gathered, until it goes back into the other side of the nozzle.
• To select the length you have to take into account 3 things: your height, the size of the shirt you wear (S, M, L, etc.) and your chest.
• The following table provides some guidance information to help you make your choice:
  

Choose the length of the backpack straps that best suits you and the material you prefer, leather or polyester. The length of the straps depends mainly on the height. You should choose the height range you are in from the following:

• People between 1.50-1.60 cms
• People between 1:60-1:65 cms
• People between 1:65-1:70 cms
• People between 1:70-1:75 cms
• People between 1:80-1:90 cms

If your height is between two of the height ranges, we recommend taking into account the rest of your build. If you are a rather thin or narrow-shouldered person, you should choose the lower height range and vice versa. You also have the option of indicating your height and any other information you consider appropriate in the order notes so that we can send you the backpack with the straps that will be most comfortable for you.
