The Jetstream Jacket is outfitted with GORE Windstopper technology, making it 100% impervious to wind, and a DWR finish allows the jacket to easily shed light rain and snow. This ability to withstand wind and light precipitation is perfectly complimented by the Jetstream Jacket's taped and skived seams, which offer added weather protection without any unnecessary bulk. In addition to its wind and weather resistance, the Jetstream Jacket is designed for maximum comfort. The interior is made from recycled polyester fabric with polyester micro-grid fleece - this delivers excellent warmth, but also allows for breathability when needed, and zippered heat-dumps in the pit areas allows you to vent off excess heat while on the move. The Jetstream Jacket also utilizes articulated patterning to promote a full range of unrestricted movement, and zippered hand and chest pockets are included to store all of your essentials. The Jetstream Jacket's ability to stop wind, shed light precipitation, breathability, and warmth makes it a perfect outer-layer for warmers days, or as a mid-layer for when temperatures drop.
