Camera bag - perfect for event photography

I am selling my Vanguard Heralder 28 professional camera bag. This bag is perfect for event photography. I used this bag many times when shooting live music events at Canadian Music Week and North by Northeast. It has an adjustable interior with sections for additional lenses and/or flash or other gear. A side pocket for a water bottle. Made of very durable material, a waterproof base, and comes with a hidden elastic protective cover for when it rains. Many more features inside, including a Velcro enclosed pocket for additional memory cards. This bag will serve someone well, as it has me. Asking $50 or best reasonable offer.
