The Grand Refuge 2.0 Extreme wader is one awesome hunting wader. This extreme cold weather duck wader has all the fabulous features of the Grand Refuge 2.0 wader but with additional insulation in the liner and boots so you can get off the sofa and fill a strap with greenheads when the weather is as bad as it gets. The removable liner is packed with 220 grams of warmth while the boots boast 1600 grams of insulation. On the chest you'll find a flip in-out style storage pouch as well as a large storage pocket with zip closure. 10 shell sleeves keep ammo at hand for quick action and to dispatch cripples. The suspenders are sewn from elastic for a comfortable fit and like the wader belt, adjust to provide a snug, no bulk fit in varying layer conditions. The upper is polyester with rugged 4 ply construction and the seat, knees and shins are reinforced with heavy, duty nylon to resist abrasion and tears. This is it. The Frogg Toggs Grand Refuge 2.0 Xtreme wader is the perfect wader for the coldest days or remove the liner for a breathable wader that is lightweight and comfortable on warm days.
