How to use: Simply put on the jacket like you would any other. Adjust the internal cuffs to seal in heat. If you're using a safety harness, use the waterproof pass - through port to wear it comfortably under the jacket. Put your essentials like keys, calls in the zippered chest, hand, and grunt tube pockets. When climbing into a treestand or drawing a bow, enjoy the free range of motion from the articulated fit. Things to note: Although the jacket is water - resistant, avoid prolonged exposure to heavy rain. Don't overstuff the pockets as it may affect the fit and movement. Maintenance: Use a mild detergent and follow the washing instructions on the label. Hang it to dry. Avoid using harsh chemicals or bleach as they may damage the fabric and insulation.
