Richmond Flying Squirrels UA Armour Fleece HoodieArmour Fleece is Under Armour's original performance replacement for old school fleece and they just made it even better. It's warmer, softer, and more plush but still has just the right amount of stretch. Updated Armour Fleece is slightly heavier but still breathable and stretchy for warmth that lets you move. Softer, more plush inner layer traps heat to keep you warm & comfortable
