there isnt much on a rider or the bike that would protect the gun from water in a downpour or puddles while riding...spend a reasonable amount of time riding in the rain and it is quite apparent that nothing stays dry that isnt bagged...

it is a pretty neat item though and coud be useful...my only concern is someone lifting the cover and discovering the gun there...it is prone to tampering and damage because it is not protected and it isnt beyond someone to take a whole motorcycle and this one comes with a bonus (although any bike with a gun locked in the bag would be too)...

cool device though...
