Flap dimensions and attachment
Specify the flap length, width and attachment concept. Identify whether removability is required or whether the illustrated fixed direction is suitable.
Show where the flap starts, its finished dimensions and the attachment concept. If removable, describe the intended arrangement for review rather than assuming the illustrated fixed design converts directly. Include the flap edge and any attachment area in the artwork drawing so branding does not obstruct it.
Worn rear coverage
Review coverage and movement in a worn rear view. Check how the flap meets the brim without making the crown pull out of position.
Review the hat worn from behind and in profile, including ordinary head movement. Check whether the flap pulls the crown or catches against the brim. A flat rear photo only shows dimensions, not how the assembled item hangs. Name the location of any concern in the sample notes.

Name the composition, weight and finish you require. Compare the cloth and decorated sample together.
Illustrative texture; not a certified fabric specification.Shell and flap match
Keep labels and artwork clear of attachment areas. Define flap and shell colors together to avoid an accidental mismatch.
Specify whether shell and flap should match exactly or form a deliberate contrast. Review the physical materials together, including their hand. A thin-looking flap and a structured shell may behave differently at the join. Keep label placement clear of the attachment and verify its orientation when the hat is worn.
Edge finishing
Confirm edge finishing and packing instructions. Additional fabric coverage does not by itself establish a protective rating.
Inspect edges, corners and attachment finishes from both sides. Discuss how the flap is arranged in the packaging and how it should look after unpacking. Extra coverage does not establish a protective rating; any intended claim needs its own confirmed requirement and supporting evidence.
A practical buying example
A buyer wants a flap extending lower at the center back while leaving more freedom near the sides. Mark that outline on a rear drawing instead of requesting a generally longer flap. Compare the resulting hang on a wearer. If the hat tips backward, review attachment and material as well as dimensions before approving the revision.
Questions to settle before requesting a sample
Choose this design when rear fabric coverage is a specific requirement. Ask whether the flap is fixed or removable, where it attaches and how its movement will be reviewed. Compare a regular all-around brim if the wearer does not need a flap. Keep the size, coverage drawing and packing instructions attached to the same style reference.
