Columbia Sportswear's Omni-Shade clothing protects you from damaging UV radiation by blocking the majority of the sun's harmful rays, so you can stay out longer. Omni-Shade blocks Ultraviolet A and Ultraviolet B rays (UVA and UVB), helping to prevent sun burn and long-term skin damage through tight weave construction, UV reflectors, and UV absorbing technology. Unlike SPF (Sun Protection Factor), which is a measure of sunburn reduction from sunblock, and does not indicate any protection from UVA rays. UVA rays are much more harmful than UVB, and are present even on cloudy days. Omni-Shade provides protection from both UVB and UVA rays. Like sunblock, Omni-Shade is given a numeric value to indicate its level of sun protection. Unlike sun block, Omni-Shade does not wear off.
Insect Blocker technology is a revolutionary defense in the battle against bugs. Using a synthetic version of a naturally occurring insect repellent found in certain types of chrysanthemums, it offers protection that is integrated directly into clothing and gear to keep mosquitoes, ticks, ants, and other biting insects away, so you can enjoy a bug-free adventure. Insect Blocker requires no re-application or special care of any kind and is so tightly bonded to fabric fibers that it retains its effectiveness for up to 70 washings. Insect Blocker turns clothing and gear into safe, long-lasting, effective insect protection to keep bugs at bay so you can enjoy the greater outdoors in peace.
