Ralf Lauren POLO Zip-up Coat/Jacket 2XB NEW WITH TAGS NOTE: Size 2XB means 2X Big, a men's clothing size for individuals with a broader or larger frame who need additional width in the chest and waist, but not necessarily extra length for height. The "B" in 2XB designates a "Big" cut, providing more room around the torso compared to a standard 2XL size, which is ideal for people who are typically too tight in the midriff and shoulders.
