Warranty & quality

Bags are batch-traceable and inspected before despatch; seams are sewn and bound — checked for aperture integrity.

Washable surface media — clean and re-use. Bags are consumables and carry no equipment warranty; a bag that fails through a manufacturing fault is replaced under the Australian Consumer Law.

Ordering

Order by part code — body, micron and collar are all in the code (e.g. MFB-S4-NM-50-P). Most configurations ship from stock; unusual combinations are made to order.
