This Eddie Bauer First Ascent long sleeve base layer is engineered for high-performance comfort during outdoor pursuits. Constructed with Polartec Power Dry technology, the fabric efficiently wicks moisture away from the skin to keep you dry and comfortable. The lightweight polyester blend features a hint of Lycra for a flexible, athletic fit that moves with you, while the waffle-grid interior texture enhances breathability. This versatile top is an essential piece for layering in variable conditions. It is ideal for hiking, cold-weather running, or as a reliable base layer for skiing.
