Key Features
Modular Capacity Expansion: A wraparound expansion zipper system extends the main compartment depth by 10 cm, transitioning the bag from a compact gym bag to a multi-day travel duffel.
Isolated Wet/Dry Compartment: A side-access waterproof compartment separates footwear or damp garments from dry clothing, welded with PEVA lining to prevent moisture transfer.
Structural Load Distribution: Handle webbing wraps around the base of the bag, secured with bar-tack stitching and box-X reinforcement to withstand up to 35 kg of static load.
Abrasion-Resistant Base: Double-layer fabric construction on the lower panel protects against rough surfaces, asphalt, and locker room floors.

Frequently Asked Questions
Q: Can we request custom dimensions instead of the standard size?
A: Yes. Provide a tech pack or dimensional drawing, and our engineering team will evaluate pattern adjustments for bulk production.
Q: What is the standard sample policy?
A: Physical prototypes can be produced based on client specifications. Sample costs are refundable upon placement of an order meeting the MOQ threshold.
Q: Are the fabrics waterproof or water-resistant?
A: Standard production utilizes fabrics with a PU (Polyurethane) backing rated at 1000mm hydrostatic pressure, suitable for light rain. Fully waterproof TPU options are available upon request.
Q: How do you ensure zipper durability under heavy loads?
A: We use #10 gauge main zippers with metal sliders from verified suppliers (SBS or YKK), backed by reinforced tape stitching to prevent zipper teeth separation under tension.
Q: Can you handle Amazon FBA prep and labeling?
A: Yes. We apply FNSKU barcodes, warning labels, and carton marks according to Amazon packaging guidelines prior to shipment.
Q: What payment terms do you accept for bulk orders?
A: Standard terms are T/T (30% deposit, 70% balance against copy of Bill of Lading) or Letter of Credit at sight.
