Keep comfortable in sunny days or heavy activity in the Columbia® OuterspacedTM Full-zip top. The 4-way comfort stretch material moves with you during jogs or yoga. Omni-WICK pulls away sweat for fast evaporation during workouts. And when enjoying the sun, Omni-SHADE UPF protection helps prevent sunburn. Wear on its own or as a layer when active. But this top looks just fabulous for casual wear, too.
