Bikepacking - a viable alternative to racks & panniers

This rack looks great for dropper + luggage. It's custom. You could design one in such a way that it takes a normal seatpack turned upside down, using the rack rails instead of saddle rails and lowest portion of seat tube/post

I wondered how light a rear rack could be made if the objective was not to carry panniers, but rather only lighter loads on top of the rack. Based on the minimum amount of tubing needed, we estimated it might be possible to actually end up with something lighter than a seat pack, and indeed this rack ended up at 320g [...] The angled top allows me to use the full 150mm dropper travel while carrying a large drybag.
