Drake Waterfowl patented Eqwader technology revolutionized waterfowl clothing and has been a core piece of the Drake Waterfowl brand since day one. Just like the Earth's equator is the dividing line between two distinct temperate zones, we noticed a similar dividing line on the body when you are wearing chest waders: cold, hostile conditions above the waders, and warm, humid conditions underneath the waders. Drake Waterfowl unique combination of waterproof/breathable fabric on the sleeves and upper body matched with ultra-breathable fleece on the lower body introduced a whole new level of comfort and performance when wearing chest waders. The moisture-wicking polyester Double Down fabric on the lower torso is 15 times more breathable than the upper waterproof Guardian Flex material and works to prevent the build-up of perspiration and moisture vapor. These dual zones of protection keep you dry both inside and outside your waders. ABOUT DRAKE: Drake forged a name for itself making innovative clothing and gear for hunters - folks who demand the most out of their gear. We struck a chord with outdoors men and women who look at the world the same way we do, and over time this crowd allowed us to make clothes that could be worn before and after the hunt as well. Today, Drake Clothing Company has a full line of clothing that draws on our roots in the outdoors. Our purpose is to capture the lure of the outdoors and take it everywhere we go. Because wherever you are, whatever you're doing, you're still always In Season.
