Using the Ultimate Direction Ultra Running Vest 6.0 is easy. First, adjust the front buckle sternum straps with T - hook adjustments to get a comfortable fit. You can put your phone in the zippered water - resistant pocket on the front chest. For trekking poles, use the 4 hooks and bungee loops, attaching them either at the front or back of the vest as you like. Fill the large rear compartment with a 2.0L reservoir if you need. Small items such as pills can go into the waterproof or water - resistant shoulder stash pockets. When it comes to maintenance, make sure to clean the vest regularly with mild soap and water. Don't use harsh chemicals as they might damage the materials. After cleaning, let it air dry. Also, when not in use, store it in a cool, dry place. Pay attention to the Comfort Cinch™ and the mesh panels, if they show signs of wear, it might be time to check for replacements. And always check the zippers before each run to ensure they work smoothly.
