Using your Kavu Rope Sling is a breeze. First, adjust the ultra - comfortable rope shoulder strap to your preferred length with the side - release buckle. You can wear it cross - body for easy carrying. Use the two vertical zip compartments to store your larger items like books or a light jacket. The two key or cell phone pockets are perfect for keeping your essentials within reach. The outside upper flap pocket and lower zip pocket are great for small items like lip balm or a bus pass. When you're out and about, don't worry about a little rain as the water - resistant polyester fabric will keep your stuff dry. To maintain your sling, spot clean it with a mild detergent and let it air dry. Avoid machine washing or using harsh chemicals as they may damage the fabric or the embroidery on the padded back. If you need more strap length, make sure to grab our compatible Strap Extension.
