The Thule Perspektiv TPGP-101 at first glance is a small bag but it is not to be underestimated. The bag was designed specifically to fit GoPro, Contour and Sony action sport cameras. The bottom half is a crushproof padded camera compartment with a divider system that snugly fits your camera. There is a flip down organization for SD cards and batteries. The top half of the case is a roll-top stash compartment with a 9 hook closure. The roll-top allows you to add as many extra items as you require and then simply roll down to keep everything tucked away neatly.
