Pierra Ment 20 is now a legendary ultralight backpack for ski alpinists. It is made of light and durable materials and the back is made of perforated EVA foam for faster ventilation. The bottom pocket is designed for cats and has a side entrance with Velcro. You can hold the skis in two ways and insert the ice ax into special loops. All equipment such as skis, crampons and ice axes can be removed from the backpack without having to throw it off your back. The backpack has a pocket on the shoulder strap for a bottle, a signaling whistle, a chest strap and a waterproof upper material.
