Bikepacking - a viable alternative to racks & panniers

Thanks! Spent a lot of time looking the mini-messenger and day pack of yours to figure out how some bits should be stitched together. Getting ready to try a slightly larger and better supported version over the next couple of weeks...

what material are you looking at? I'd suggest a 500d PU Nylon. Super tough but also light and plyable

also you have bigger balls than me sleeping on the ground without thermarest!
