Our Arc backpacks feature a removable and interchangeable belt. This is a useful feature if you lose or gain weight, or if the pack is transferred to a different size person. If the belt wears out before the rest of the pack you could replace it.

A 10.5" horizontal belt stay is required to attach a belt to one of our framed packs.  

• To measure your belt size, pull a string or cloth tape measure tight around the spot you’d like your belt to ride. Choose a belt with a minimum adjustment of a couple inches smaller than your actual waist measurement. This will leave room for you to tighten down the belt if you lose a little weight on trail.
• Do not rely on your pant size.
• The padded portion of the belt is 1" shorter than the listed minimum adjustment. For example a "Medium (30-35 inches)" belt has padding which measures about 29" tip to tip, and has a minimum adjustment circumference of 30". It is the recommended size if your actual measurement is 30-35" however the webbing extends further.
