To use this Sitka men's fleece jacket, simply zip it up. It can be worn alone in mild weather or layered under a heavier coat in cold conditions. When you're working hard and sweating, the wicking back will keep you dry. As for care, follow the washing instructions on the label. Usually, it's best to machine - wash it in cold water on a gentle cycle and tumble dry on low. Avoid using bleach as it may damage the DWR treatment and the fabric. Check the jacket regularly for any signs of wear and tear, and if there are small rips, you can mend them promptly to keep it in good condition.
