Leading designer of sportswear and golf apparel, Ashworth Inc, has begun shipping its new Callaway Golf apparel line into 1,000 stores across the US.

The California-based company decided to start shipping the new line after strong demand from retailers ahead of  the line's launch this June. The line features two collections, one for evenings and office settings and the other for on-course play.

Ashworth said on Tuesday that interest and demand in the range has been very high and surpassed sales projections.
