Trench coat fabrics are lightweight, water-repellent, and structurally durable fabrics used in the production of classic trench coats, raincoats, and seasonal outerwear. Gabardine, cotton-blend woven fabrics, and polyester ripstop are the main types.

Trench coat fabrics, produced in a weight range of 200–350 g/m², are preferred for four-season outerwear due to their rain resistance, ironability, and shape retention. Waterproof membrane types are also available.

Trench coat fabrics, used for sewing classic trench coats, light coats, spring raincoats, and seasonal jackets, are offered at Çerçiler Kumaş in beige, brown, black, and cream color options, 150 cm wide, by the meter.
