Bikepacking - a viable alternative to racks & panniers

A couple of days late but another solid recommendation for Quadlock from me. I've got one of the older ones, just looks slightly different, but I had it on a previous (waterproof - I agree, @hippy) phone, then had to slice it off which was quite an effort, and used Araldite to stick it to the back of my new phone (Moto G3, awesome and waterproof). It's survived years of commuting, a few tours and a number of days bone-shaking mtb so I have total faith in it. Not sure if I'll be able to use it on another phone some time in the future or if I'll need to buy another...!
