EVOCHANDLEBAR PACK BOA Handlebar Bag Bicycle Bag for Additional Storage Space (Large Storage Space (2.5L or 5L), BOA Fit System, Quick Access on Both Sides, Waterproof and Dirt-Repellent)

I bikepack and carry mad weight on my back. I wanted to pack a tent liner, bike repair kit, and some extra calories/batteries.This thing is rainproof and did the trick! It won't prevent water ingress from fog and humid areas but will absolutely keep things dry from rain.
