With these 8 ballast bags that can be divided in 4 compartments choice in front and behind as you can modulate the charge to take. Very convenient!
The vest itself is leather or equivalent, that is very robust! I eliminated other weighted vests as they seemed not sturdy at all. Therewith, without risk. I even said to myself that if I fall bike, protect me well and do not stumble !!!
The straps are adjustable at will. I'm not thick nor weakling and there is plenty of room in the 2 directions.
I am completely satisfied with this purchase.
The packaging was perfect!
