The Armada Haven Base Layer Top is a lightweight and minimalist base layer designed for every day on the mountain. Slip on this next-to-skin top made with recycled polyester and elastane, that stretches as you move and wicks moisture when you sweat. Extra UPF 50+ protection keeps you safe from the sun when it's too warm for layers and comfortable chafe-free seams means less rubbing when you layer over the top.
