PRODUCT CONSTRUCTION
One roll-top body with accessible exterior storage
Start with the items your buyer will carry and how often they need access. Keep the main compartment, exterior pockets and carrying arrangement as separate lines in the purchasing brief so each function can be evaluated on the selected sample.
Front and side storage
The front zipper and flap pockets, plus side mesh storage, offer separate access points. Specify their dimensions, intended contents and protection requirements individually.
Handle and backpack carry
Review the top handle, shoulder straps and attachment positions with the intended load. Agree adjustment, component selection and the carrying details needed for your range.
