Using this saddle pack is a breeze. First, open the roll - top closure and put your light, compressible items inside. Then, adjust the capacity by rolling down the top as much as you need. Attach the pack under your saddle using the three - point attachment system. Make sure it's secure to avoid swaying during your ride. When it comes to safety, take advantage of the light attachment points to add small lights. Also, the reflective feature will keep you visible in different lighting conditions. For maintenance, clean it with a mild soap and water when it gets dirty. Don't use harsh chemicals as they may damage the waterproof laminate. Store it in a dry place when not in use to prolong its lifespan.
