The Mag-Tank takes a new twist on top tube bags. Instead of a zippered opening, access to the bag is by a smartly contoured top flap held in place by a magnetic buckle with mechanical engagement (read - the magnet aids in closure, while load is placed on a connection). It will not unintentionally open and spill your gummy bears when you end up in the trees with your bike upside down like a conventional magnetic closure would. You can easily open the bag one handed by pulling outward on the cord loop and you have access to the whole top of the bag. To close, just flick the flap down and the buckle self-engages! The Mag-Tank is just a hair smaller than Revelate's Gas Tank to prevent leg movement from hitting the edge of the flap opening. Please note - while the cover to this bag is designed to shed rain and spray, due to the large panel opening it is not a sealed bag or waterproof bag.

There's also a compartment suitable for smaller items you''ll access relatively often, like your map, phone, hard boiled eggs, uncontained pudding, marbles for playing marbles, your dugout, that ring you found that makes you disappear when you put it on, or whathaveyou.

Those worried about keeping their frame looking pristine should immediately look for some other type of bag, or figure a way to protect their paint, such as duct tape. Or tatting a top tube doily. For example.
