Extremely versatile - the Columbia Horizons Pine Interchange Jacket is a great combo of a weatherproof outer jacket and a warm inner jacket. Both jackets can either be combined using a zip-in and 3-point system or worn separately. The outer jacket is made out of a tough polyester with an Omni-Tech membrane. Plus, it has been treated with a DWR, so the fabrics both water repellent and quick-drying. If it just keeps bucketing down with no sign of stopping, the membrane will keep water out of the interior. Plus, any moisture or sweat on the interior will be able to escape to the outside. As for the synthetic jacket, it is equipped with Omni-Heat polyester lining. The insulation boasts a good weight-to-warmth ratio and will make for a balanced environment on the interior. Even when wet, it will retain its insulating properties. The detachable hood can be adjusted for a perfect fit using the drawcords. Both the hem and cuffs can be adjusted as well, making the Horizons Pine Interchange Jacket completely windproof.
