Products using the COR3™ Technology fabric finish have a UPF rating of 30 or greater, properties to minimize odor and outstanding wicking performance for important moisture management. The anti-odor finish helps control odors caused by a wide range of microorganisms (mold, mildew, algae, yeast) is compatible with virtually all fabrics. All of our performance cotton clothing utilizing COR3™ also feature COR3™ EZ. The "EZ" means easy care and indicates that garments featuring this treatment will travel well and resist wrinkles.

Chemical-Free Cooling Technology While the other makers of cooling fabrics use a number of chemicals to enhance wicking, transportation and evaporation, Coolcore fabrics are chemical free. To make that possible, we changed the essence of cooling fabric technology right down to its very core.

Coolcore is a research proven performance fabric technology that adapts to its environment and regulates temperature by managing heat and moisture. The proprietary construction helps manage and distribute your body heat, and if you work up a sweat, it rapidly cools through regulated evaporation. Whether for the casual or athletic minded… Coolcore has the ability to change your personal environment and greatly improve your overall well being.

Polygiene is a natural and permanent odor-control fabric treatment that stops odor-causing bacteria, allowing you to wear more, and wash less. Based on natural silver chloride from 100% recycled silver, Polygiene is permanently applied to each garment without the use of chemicals or additional water or energy, helping you stay fresh when you're on the go, around town or deep in the backcountry.


Through a combination of fabric construction, design and finish, Solarflex offers UPF50 sun protection. UPF is a measure of how much of the sun's UV radiation is absorbed by the fabric. A UPF 50 rating means that only 1/50 of the sun's UV radiation will pass through the garment.
