I've got size 10 feet and use 'approach' type trainers which pack better than more rigid trainers. I've use the tank bag to carry trainers and a pair a jeans. All bets would be off if your'e 6'6' with size 15 boots You should be able to squeeze in trainers, jeans and a top however you might need to use the expansion zip. I also use walking trousers rather than jeans as they fold up smaller, are lighter and dry quicker if you get them wet.

That way I could leave both tank bags ready to go without swapping components between them. I purchased a Givi S111 USB Power Hub and changed the connector. Yes there is cutout to accept the power lead. Opening up the expansion zip gives another inch or so of internal height however it starts then starts to obscure the display. No a problem for me as I use a Navihalter which mounts the sat nav above the display. The bag will obscure a sat nav mounted on the handle bar clamp.

I use a number of dry bags/sacks for spare gloves, visor cleaning kit etc. The tank bag does come with a rain cover but I never use covers on tank bags.

You'll notice there is an internal bag with a draw string which I assume is to provide a degree of rain protection. Hi created a photo album showing the internal dimensions, together a picture showing the amount of expansion available, plus pictures of the map/tablet carrier.
