Review on MaxMiles Waterproof Bicycle Pannier Bag: 35L Expedition Rack Bag for Bike Rear - 2100cu inches Capacity by Ayush Bonuccelli

This bag is one of the most well thought out and well made products I have seen. "Hidden" panniers are amazing. The way this bag expands and then folds back into a more compact state has been engineered to perfection. All zips work perfectly, the sturdy side walls of the case keep the shape of the bag. I couldn't be happier. It's worth it. UPDATE: 14 months later. NOT WATERPROOF. The product name says "waterproof". The description says "waterproof". Even water resistance is too strong a word. I left the backpack on the bike while washing. The backpack had zippers all over. Everything in the backpack was soaked. I still love the design but don't expect your stuff to stay dry in the rain.
