The concept behind our Zephyr Oxford fabric is simple: we took our best-selling Cambridge Oxford cloth and re-engineered it for the warmer months. The result, an Oxford cloth with a crisp hand, breathable weave, and high thread count for added comfort on warm days. As it turns out, all of this was achieved with one simple change: thread gauge. Our Zephyr Oxford uses 80’s singles threads, which are twice as fine as those used in our Cambridge Oxford. Other than that difference, all characteristics remain the same.
