Have the mast bag (takes 3) was stunned with the build, didn’t expect it to be of such good quality material, or such a good design, taking into account the price of the item.
Don’t know about security on top of the vehicle. Its a woven canvas type fabric, but still can be cut away.
There was something on Forums ages ago from the UK that allowed items to be locked to roof racks, but even those (roof racks) can be removed in a few seconds. Not a good solution to leave them un-attended.
But the bags, top gear and an affordable price
