ROCKBROS Waterproof Pannier pops out of the sides of this handy pack that sits on top of your rack and is held in place with hook and loop straps. It’s only got a 10L capacity, but the versatility makes up for the shortage of space. You can use that main section for your day-to-day carrying and then unfold the panniers as and when you need them. BUY HERE → http://bit.ly/RockbrosWaterproofPannier
