Unpredictable weather won't stand in our way of an adventure day with the GORE Wear TrailKPR Hybrid 1/2-Zip Jacket. Whether used with a base layer or on its own, the hybrid thermal layer keeps us warm and protected from the elements with its water, wind, and abrasion-resistant panels. When we start to overheat, we quickly unzip the 1/2-front zipper to allow for ventilation and easy removal.
