Using this Sitka men's jetstream jacket is easy. Just put it on when you head out for outdoor activities like hiking or hunting. The pit zips can be opened when you start to feel hot during movement to let the heat out. You can use the zippered hand and chest pockets to store small items like keys or a phone safely. When it comes to maintenance, machine - wash it in cold water with mild detergent. Avoid using bleach as it can damage the fabric and the water - repellent finish. Tumble dry on low heat. Make sure to close all the zippers before washing to prevent any damage. Also, keep it away from sharp objects to avoid tearing the fabric.
