Comfortable bag - Deuter Compact EXP Air 10 Bike Pack

Very comfortable bag. Vented is good. Back not sweat, but lower back is still sweat a little, but it's not a problem.
I noticed one cons, the material is not very durable.
Generally a good backpack, even if its load, do not feel that heavy backpack.
Good hydration bank.
