A wetsuit having an outer and/or inner surface is manufactured from an improved non-absorbent and quick drying fabric. The improved non-absorbent and quick drying fabric is made of 100% non-absorbent fiber, selected from polyester, having a fineness ranging from 30 denier to 75 denier, and pre-processed with water repellent before being knitted, then knitted by a single circular knitting machine under a setting of 18˜44 gauge per inch. The result is an improved fine, thin, non-absorbent, and quick drying fabric, which prevents the penetration of water molecules. The improved non-absorbent and quick drying fabric is laminated with a rubber sponge material to form an improved non-absorbent and quick drying wetsuit material. Appropriate cutting and sewing processes are employed to finish the formation of a wetsuit and the improved non-absorbent and quick drying wetsuit is lighter and dries quicker when the wearer leaves the water since less water is absorbed by the wetsuit fabric as compared to a conventional wetsuit.
