Columbia bought a few of these Columbia Silent Shell Waterfowl Vests for those of you who can wear a 4XL. These are constructed of Columbia's Silent Shell fabric, which has a smooth hand, is highly breathable, and is also highly wind-resistant.
The front features twin hooded zip front pockets, and two hand-warmer pockets behind. It also has two zippered vertical chest pockets for do-dads. Dual side drawcords with locks hem in the warmth of the shell. The fabric has excellent 4-way stretch, for comfort as you move or sit.
Sizing Tip: They measure 66" through the chest, and are 30" down the back.
