This Capilene® 4 Expedition Weight is Patagoinia's warmest synthetic baselayer, and we've improved it this season to breathe better and dry faster during high-output activities in cold conditions. A smooth jersey face glides beneath layers and the soft, brushed fleece next to the skin warms and wicks. The collar fabric is reversed for softness and warmth. Offset shoulder seams eliminate pack-strap rub. Made with 5.9-oz Polartec® Power Dry® with Gladiodor® odor control for the garment. Recyclable through the Common Threads Recycling Program.
