Much like the moon blocks the sun during a solar eclipse so does the Marmot Eclipse Jacket block the rain when thunderstorms threaten your day on the trail. Part of Marmot's EVODry collection this technical jacket features a waterproof membrane and fully sealed seams so you stay dry even if it rains for the last three hours of your hike. As the name suggests though this 2. 5-layer MemBrain is still smart enough to allow for water vapor to escape if the trail gets steep during the storm. The Eclipse boasts plenty of features to make your adventures run smoothly. Marmot incorporates its Angel-Wing Movement design into this shell allowing full and easy mobility including gusseted shoulder so you can reach on a climb without the jacket pulling out of your harness. Underarm vents can be unzipped if you need to dump heat while the rain is turned on the pockets are strategically placed for access with a pack equipped and an adjustable hood hem and cuffs help seal out the wet chill.
