Just like the Earth's equator is the dividing line between the distinct tropical and polar temperate zones, there's a similar dividing line on the body while wearing chest waders: cold, hostile conditions above the waders and warm, humid conditions underneath. That's the premise of Drake's patented Eqwader technology. It combines waterproof/breathable fabric on the sleeves and upper body and ultra-breathable fleece on the lower body to give you the best of both worlds. The 100% waterproof Guardian Flex material on the upper keeps you completely dry, while the moisture-wicking Sherpa fleece on the lower torso works overtime to prevent moisture-vapor buildup. These dual zones of protection keep you dry both inside and outside of your waders.
