Grivel Radical Light 21 is a backpack designed for mountaineering and long multi-pitch routes in the mountains. Its capacity of 21 liters allows you to store everything you need inside for the day on the wall. The closure takes place at the top through a lanyard so as to make the operation super fast and to compact even everything contained inside the backpack. Externally the line instead is very simple and essential without straps or pockets so as to avoid annoying entanglements. You will only find a convenient zippered pocket on the front, two ice-pick holders and a strap at the top for carrying the rope. Grivel Radical Light 21 climbing and mountaineering backpack
