The comfort with excellent ventilation is unfortunately at the expense of durability because the mesh fabric (sides and top of the fingers, the outside of the thumb and back of the hand) is not particularly robust.
This is my second pair, after about 2 years rips the fabric in the forefinger flexor one, after being scuffed etc by friction, brakes, then also had smaller holes at the back of the hand and the thumb, you stay anyway times where slopes ..
The glove must be with me but also participate a lot, so that the life in the comfort and price quite OK for me.
