Clog specialist Crocs has added a new string to its bow through the introduction of a branded apparel line.

The Colorado-based firm, which has achieved massive growth through a range of shoes made using the patented material Croslite, will launch its previously announced apparel line to consumers in October.

Prior to this, retailers have been given their first opportunity to view the Crocs' Holiday 07 apparel lines, for men and children, at the Magic exhibition in Las Vegas this week.

Select pieces in the men's apparel collection incorporate a new form of Croslite called Croslite rt, which stands for "relaxed technology."

This material is said to make garments lightweight, versatile, breathable, and durable, as well as being resistant to harsh chemicals and heat, ensuring longevity after exposure to sun, UV light and sweat.

"A broad range of consumers have become familiar with Crocs' unique material, Croslite, and the benefits it provides to footwear," said Ron Snyder, CEO of Crocs.

"We are excited to now have the ability to develop and integrate a new form of Croslite into Crocs Apparel that is ideal for function, performance and comfort."

The collection includes Niwot short and long sleeve tees, retailing at $36-$40, and White Rock long and short sleeve woven shirts retailing at $54-$58, which have portals in the chest pocket for earphone wires.

All shorts, pants and skirts in the children's line can be accessorised and customised with Jibbitz charms from the company's Jibbitz subsidiary.

Crocs also has plans to introduce a spring 08 apparel line to expand the use of Croslite rt.
