OIC Columbia Sportswear is making a significant expansion into the performance underwear category through an exclusive global licensing agreement with Delta Galil Industries. Under the contract, the Israeli firm, which is already Columbia's global licensee for socks, will produce a range of Columbia branded products including men's and women's underwear as well as a full collection of women's sports bras. The items will be engineered with anti-microbial properties and other special features for moisture management and other functions.
