More durable material
OUTSIDE - 300D Oxford
300D Oxford cloth is stronger than 210T/190T polyester, because it has thicker yarns. It is better for wear-resistant and tear-resistant, It can keep long time in extreme weather such as sunlight, rain ,snow and so on.
INSIDE - PVC Coating
The yarn of Oxford cloth is thicker, the gap between the yarn is larger, so it need PVC coating to improve its waterproof effect. The general PU and PA coatings cannot meet its waterproof requirements, will leak after use some times . but pvc coating will last longer time.
