We compared two pairs of rear rack bike panniers: the ROCKBROS Bike Pannier Bag 100% Waterproof and the MOSISO 20L Bike Panniers.
What we looked at
Capacity, waterproofing and closure design, and price.
The verdict
If you want maximum capacity and a fully sealed waterproof build, the ROCKBROS is the pick at £65.59. If you would rather save £28.60 and get a lighter pair with a carry handle, the MOSISO is the alternative, at £36.99.
A £65.59 pair expanding to 32L with a fully sealed waterproof build.
A £36.99 pair of 20L panniers with a carry handle.
