Materials & Suitable Fabrics
- Main Body Fabric: Glass-bead or micro-prismatic retro-reflective fabric with a charcoal-grey daytime cast that lights up white under illumination.
- Reinforcement & Base Fabric: 1000D Cordura nylon or heavy-duty ballistic nylon in matte black to protect high-wear bottom areas.
- Lining: 210D ripstop nylon for lightweight interior durability and water resistance.
- Webbing & Straps: 1.5-inch heavy-duty nylon webbing for handles and shoulder strap mounting.
- Hardware: Heavy-duty #10 YKK moulded tooth zipper for the main compartment, #5 YKK zippers for cargo pockets, metal D-rings, swivel hooks, and side-release buckles.
- Interfacing/Stiffener: Heavy plastic piping for structural edge framing and thin EVA foam sheet for cushioned structure in the base and handles.
Medium Bag Dimensions & Measurements
- Main Body Cylinder: 20 inches (51 cm) length times 10 inches (25 cm) diameter.
- End Circular Panels: 10 inches (25 cm) diameter circle.
- Exterior Cargo Pockets (Front): Two patch pockets, each 6 inches (15 cm) wide times 7 inches (18 cm) high with a 1.5-inch expansion pleat.
- Handles: 24 inches (61 cm) length for standard hand carry; adjustable shoulder strap extending to 48 inches (122 cm).
Pattern Drafting Guide (Full Complete Bag)
- Main Body Panel: Draft a rectangle measuring 32 inches wide times 11 inches high (includes 1-inch circumference ease and seam allowances) on the reflective fabric.
- End Circular Panels: Draft a circle with a diameter of 10.5 inches (to account for a 1/4-inch seam allowance around the perimeter) for the two side caps.
- Cargo Pocket Panels: Draft two rectangles measuring 9 inches wide times 8.5 inches high to allow for side expansion box pleats and top hem folds.
- Handle & Webbing Placement Lines: Mark horizontal guidelines across the main body panel spaced 4 inches apart from the centre zip line to position the wrap-around carry handles securely.
Seam Allowances
- Standard Construction Seams: 1/2 inch (1.3 cm) for all main structural joining lines.
- Binding & Edge Finish: 1/4 inch (0.6 cm) for bound interior seams using grosgrain ribbon to prevent fraying of technical textiles.
Construction Instructions & Sewing Tips
- Preparing Cargo Pockets: Sew the expansion box pleats onto the exterior cargo patch pockets, install top zippers or flap closures, and stitch them securely onto the front main body panel before assembling the cylinder.
- Attaching Webbing Handles: Stitch the heavy-duty nylon webbing down the face of the main body panel, reinforcing the stress points near the top zipper zone with an 'X-in-a-box' stitch pattern.
- Installing Main Zipper: Install the #10 YKK zipper along the top 32-inch edge of the main body panel, adding wind-guard flaps underneath for weather protection.
- Joining End Caps: Form the main body panel into a tube by sewing the short ends together. Pin the circular end caps to each opening, easing the curves carefully, and stitch around the perimeter. Bind raw interior edges with grosgrain tape.
- Lining Integration: Construct a matching inner bag using the 210D ripstop nylon, slip it into the outer duffle shell, and hand-slip-stitch or machine-bind it clean along the zipper tape interior.
Pro Sewing Tips
- Needle Choice: Use a heavy-duty Size 90/14 or 100/16 Microtex or Denim needle, as retro-reflective fabrics feature dense technical coatings that can dull standard needles quickly.
- Tension Adjustment: Test your stitch tension on scrap layers of reflective fabric and Cordura nylon; use a walking foot to ensure smooth feeding across multi-layered webbing and thick seams.
