I need a production-ready design for a full-face cotton mask aimed at Indian motorcyclists who battle heavy dust and pollution on a daily commute. The core requirements are straightforward: the mask must give reliable particulate protection, stay breathable in hot weather, and close securely with Velcro. Key features I want designed in from the start are breathable fabric panels and fully adjustable straps so riders can fine-tune the fit even when wearing a helmet. The overall shape should cover the nose, mouth, cheeks, and extend under the chin without blocking peripheral vision or interfering with helmet padding. Here’s what I expect as hand-off: • Concept sketches that show front, side, and worn views • A detailed tech pack with fabric specs (preferably 100% cotton outer with a tightly-woven lining), Velcro placement, strap dimensions, and stitching guidelines • Flat patterns in PDF or DXF ready for sampling • A short fit and airflow test note confirming the design remains breathable at idle and cruising speeds If you have prior experience designing motorcycle or outdoor gear, do highlight it—functional insight will help us move from drawings to a working prototype quickly.
