Topeak MTX Trunk Bag DXP (Black) (19.4L) (w/ Expandable Panniers)
I used this trunk bag on a week long inn-to-inn bicycle ride. This system is the PERFECT one for that purpose. I was easily able to hold everything I needed and, because I used Amtrak, was able to slide the whole thing off my bicycle in seconds so I could hang my bicycle in the compartment meant for that purpose.
Its made of very tough material, all aspects (including the zipper), are first rate quality and function.
The only possible design flaw may be that, in order to carry the system there's either a handle or a shoulder strap. The handle's placement results in the zipper taking on the entire weight of the system. As such I used the shoulder strap instead, having it do double duty by wrapping the strap around my seat post as a back-up safety system just in case the latch holding it all to the rack failed.
Make sure you also purchase the rain cover which is sold separately. In case you think that's a bad idea, note that at least you have a choice whether to buy it or not, otherwise the price would go up anyway.
I highly recommend buying the Topeak MTS Trunk Bag DXP.

This bag is great, however the back of the bag is not like the photo on your website. I have the same one I purchased several years ago and it has black interior and a buckle to tighten the rear bottle holder. Still it is a great bag.

It finally wore out. I have been using the one I purchased in 2014 for 7 years. Over time, with moisture, salt, sun exposure, and carrying loads that might have been a bit more than expected, it finally ripped out. Sometimes I felt like a pack mule, but this bag never let me down. Purchasing another as a type. A Great Value!!!
