Drake's patented Eqwader technology revolutionized waterfowl clothing and has been a core piece of the Drake Waterfowl brand since the beginning. The Drake MST Eqwader Plus 1/4 Zip Hunting Shirt raises the bar for innovation and hunting performance by utilizing Drake's Instinctive Features with an updated design that delivers increased performance in the field. The EquaderPlus also has an adjustable Neoprene Cuffclose. Each neoprene arm cuff tightens with a Velcro strap on the outer layer to seal out rain and swamp water. The Drake MST Eqwader Plus 1/4 Zip Hunting Shirt features HyperShield Technology - Laminated to Refuge HS outerwear fabric, HyperShield Technology guarantees protection from the elements. HyperShield is an impenetrable membrane that blocks out external wind and rain, yet allows internal moisture vapors to escape. To add to the waterproof capabilities of HyperShield Technology, Drake adds an external water-repellant finish and seam-tape all the seams on all of their clothing as two more fail-safes to keep hunters dry as a bone. Another great feature of the EquaderPlus is Refuge HS. Refuge HS (Hard-Shell) is another innovative material brought to you by Drake. Combining the toughest and strongest fibers available enables this material to stand up against all of the elements a hunter faces with very little maintenance.
