Apparel giant Wrangler is to release a range of authentic Western clothing featuring high-tech temperature balancing fibres aimed at keeping the skin cooler longer in direct heat from the sun.

The new Cool Lock shirt collection contains Comfortemp materials in the yoke, collar band and sleeve cuffs that are designed to shift perspiration away from the body 60 times faster than cotton yarn to keep skin dry and comfortable in hot weather.

The patented, synthetic yarn has been developed by North Carolina-based Frisby Technologies Inc, with the new shirts due to go on sale in more than 2,500 stores across the US over the next few weeks.

"The Cool Lock shirt by Wrangler is the first shirt on the market that uses a combination of Comfortemp and special synthetic fabric with maximum wicking properties to absorb heat and moisture, keeping consumers cooler longer," commented Joe Hertz, VP GM, Wrangler Western Wear.

Greg Frisby, chairman and CEO of Frisby Technologies, added: "While Cool Lock may first appear on the range, we think you'll likely see it worn everywhere fashion and function matter. We look forward to a long and mutually rewarding relationship with our new partners at Wrangler."
