Product Information
For technical alpine routes or side-country powder searches, choose simplicity over complexity. This lightweight yet warm crew sticks to the essentials with our versatile Capilene® 4 Expedition Weight fabric. It's the warmest and most breathable synthetic baselayer in the Capilene® family, made to keep you dry and comfortable in cool-to-cold conditions. Soft, stretchy and compressible, it has a smooth face that glides beneath layers and a brushed fleece interior to warm your core, wick moisture and feel smooth against your skin. Articulated, offset seam sleeve construction allows complete shoulder mobility and hidden thumb loops ensure wrist coverage. The drop-tail hem stays put under a harness. Made of 3.8-oz Polartec® Power Dry® High Efficiency™ fabric with Polygiene® permanent odor control. Fabric is bluesign® approved.
