Before hitting the outdoors, you weigh many factors in the hopes that the time you spend will be rewarded: You consider the weather, how much time you have, your equipment, and who you will go with. But if you’re not comfortable, you’re not having fun and nothing else matters.

C4’s exclusive TECH2O apparel is a newly-developed technical performance fabric. It presents a fresh alternative to skin tight lycras or rash-inducing fabrics that only become more abrasive when wet. TECH2O‘s feather-light wicking weave is designed to be worn both in the water and on land. Coupled with an ultra-soft feel and form complementing cut, this unique polyester knit offers the kind of quick-drying superior breathability required to keep your body cool and comfortable. The next time you’re ready to step outside, think TECH2O. Think C4.
