The Lowepro Flipside Sport 20L AW is a full-size backpack with a little bit of extra ventilation on the back and straps (for sporting comfort) and a streamlined design (so it doesn't get hooked up on sports things while you're sporting). A removable inner camera compartment (measuring about 16x26x38cm) makes cleaning easy, because us sports fanatics know that sports can be a dirty business. Well, it's time for me to get back to doing the sports, but you should do a "home run" to the store and pick up this camera bag, it's a real "field goal." In excellent condition, with light wear
