The description of products is good but the exact dimensions and the weight of the different models do not seem the right ones?
Is it possible to have a more precise description or contact the seller. Including 600 g for 21.5x22x29 model (cm?) And 50 g for size L. The model I think it is impossible to have a saccoche of 21x17x31 cm weighing only 50 or 60 grams.
