How to use: You can wear this Sitka hoody as a mid - layer under a jacket on cold days or as an outer layer when it's not too chilly. Just zip it up using the half - length YKK® zipper at the front. Put your hands through the stretch thumb loops for a more secure fit. Keep your small essentials like keys or a phone in the YKK® zippered chest pocket. Things to note: Don't pull too hard on the thumb loops or the zippers as they may break. Avoid sharp objects that could damage the fleece fabric. Maintenance advice: You can machine - wash this hoody in cold water. Use a mild detergent. Don't use bleach. Tumble dry on low heat or hang it to dry. This will help keep the Polygiene® Odor Control Technology working well and maintain the quality of the fabric.
