Suitable for use as either a base or mid layer, the Armada Hideout Midlayer Top is built of stretchy and super warm Polartec® Power Grid fleece that creates instant heat and feels silky soft on the skin. The Power Grid fabric has a waffle-knit pattern that creates extra pockets of warm air and also promotes breathing and wicking. The Hideout has a tall neck to offer more protection from the wind and a zippered stash pocket at the left hip.
