Casual clothing giant Levi Strauss & Co has reported a leap in second-quarter profit due to expense controls offsetting sales slumps.

Profit rose to $27 million compared to $6m in the same period last year, while second-quarter net sales fell 1.6 per cent on a reported basis to $944m from $959m a year ago.

The sales slump can mainly be attributed to actions taken to streamline the number of US Levi's and Dockers product offerings, lower sales of US Dockers women's products, the impact of lower sales in Europe resulting from a change in the region's spring/summer sell-in calendar and a declining retail environment across Europe.

However, the Levi's brand saw continue growth within the Asian market, the company reported.

"We're right where we expected to be midpoint in the year," said Phil Marineau, chief executive officer.

Levi Strauss & sells its jeans and sportswear under the Levi's, Dockers, and Levi Strauss Signature names in more than 110 countries.
