A molded fit shell integrated into a broad flexible torso band, developed around the exact shell reference, textile construction, wearer range and approved carry positions.
Band-and-shell architecture
The shell controls fit and retention while the textile band distributes load and accommodates body movement. Band stretch, seam placement, pocket construction and shell attachment can change opening geometry, access and stability.
Program decisions
| Decision | Buyer input | Approval evidence |
|---|---|---|
| Wearer range | Approved circumference, size grading and garment condition | Representative fit matrix |
| Band construction | Material, width, stretch/recovery, seams and closure | Identified textile assembly |
| Shell interface | Pocket or mechanical joint, position and removal/service needs | Loaded attachment inspection |
| Movement | Permitted positions and stability/access test | Rotation, slip and handling record |
Sample approval focus
Inspect size adjustment, closure security, band recovery, seam/edge contact, shell position, retention, access, loaded movement and any change after agreed moisture or cleaning exposure.
