The SAKA is an ergonomically shaped magnesium bag. Developed by Petzl, this small bag has an oval shape with a large opening that allows for a full hand.

Made of nylon and polyester, the soft material of this magnesia bag does not cause discomfort when worn with a backpack or when the climber is leaning against the rock.
Its closure system is well-functioning thanks to a central drawstring and can be opened with one hand.

It also has a rigid textile brush holder with two loops to hold all types of brushes.
