The 66 North Oxi Power Stretch Prima Jacket is perfect for any adventure - no exceptions! Honestly, this synthetic jacket leaves nothing to be desired. The body and collar are insulated with soft Primaloft Gold, which is not only extremely lightweight and low-maintenance, but water repellent and quick drying. Plus, the silver lining reflects your body heat back to your body. The water-resistant DWR finish protects against light rain, and dirt can be easily brushed off. The sleeves and sides are made out of Polartec Power Stretch fabric. Both the high breathability as well as the moisture-wicking capability make the jacket really comfortable to wear, even when the going gets tough. In the two side zip pockets, you can warm up your hands or safely store any important items you may have. Regardless of whether you're going for a long hike or out ice climbing, the Oxi Power Stretch Prima Jacket won't leave you out in the cold.
