The cotton/polyester blend is a 10oz fabric and is a mixture of 60% Cotton, which gives the garments a very comfortable feel, and 40% polyester which will ensure the garment washes extremely well, has very little shrinkage and a very high colorfast rating. In addition, the added polyester gives the garment greater strength and a longer life span. This range is available in 4 colors, black, brown, gray and navy. If you are looking for functional garments, which will also offer a professional image and re-enforce your company's corporate identity, then this is a range we would highly recommend.
