Using the Quest PFD is easy. First, put it on like you would any regular life jacket, making sure it fits snugly. Adjust the straps so it doesn't move around too much while you're paddling. When you're out on the water, use the front pocket to store your keys or your iPod. The 1.5L water bladder can keep you hydrated, so fill it up before you head out. The D - ring attachment is great for hanging small items. As for safety, the reflective patches and piping help others see you, especially in low - light conditions. When it comes to maintenance, after each use, rinse it with fresh water to get rid of any salt or dirt. Let it dry completely in a shaded area. Don't leave it in direct sunlight for too long as it can damage the material. Check the straps and attachments regularly for any signs of wear and tear. If something looks damaged, replace it before your next use.
