1200D Oxford fabric is a heavy-duty material that is often used in outdoor gear and equipment, such as tents, backpacks, and luggage. The “1200D” refers to the denier count, which is a measure of the thickness and weight of the fibers used in the fabric. A higher denier count indicates a thicker and stronger fabric. Oxford fabric is a tightly woven, durable material that is resistant to water and mildew. It is also known for its abrasion resistance and high tear strength.
