The fabric used in these suits has been developed to offer exceptional elasticity and superior crease recovery without synthetic fibers. This is the top end fabric offered by Jack Victor. Jack Victor garments have almost 300 individual operations (cutting, pressing, or sewing) that contribute to the final tailored coat or suit. A dedicated workforce and careful production supervisors create products that result in men's clothing of remarkable consistency and high quality. Jack Victor suits and coats are not available by three day air. Regular ground only. Please allow about 10 days for delivery. Nice comment from Kevin M: Hi Kent. A word on the JV suits. I wore one the other day and was marveling at the comfort (the black striped one). See, as a court reporter, I sit there all day in court and comfort is an absolute essential for me. Any itch drives me nuts, no matter how fine the wool is.Hence, the lightweightedness of the JV suit is tremendously attractive to me.
