Design: The Chitkul Tank Guard bags were designed to be the slimmest bags available for the Himalayan 450 tank guard frames. To avoid unnecessary fiddling with straps between the frame and the tank, we came up with a slide lock mechanism that is easy to mount and your bags can live on the bike without having to be removed all the time. Specs: 4L+4L capacity  27 cm X 19 cm X 6 cm 1 primary waterproof compartment1 external side pocket Compatibility: Himalayan 450 Mounting: Slide lock mechanism to fit the metal loops that come with the stock tank guard on the Himayalan 450.
