For ambitious hikers who want to move fast in the mountains without worrying about weight. In fact, its construction, the materials used, the Lite Air back system, and reduced features combine to make the new Speed ​​Lite Pro even lighter than its predecessors. This backpack weighs only 680 grams! This means you can dedicate more energy to the trail and less to carrying your load. The wide, ergonomic shoulder straps with full ventilation, flexible hip fins, and a lightly elasticized and precisely adjustable sternum strap create a snug fit with zero load sway and distribute weight evenly between hips and shoulders. This minimizes strain on them and, consequently, on your back. The pockets on the shoulder straps and hip fins have space for a bottle, energy bars, a mobile phone, or a GPS device. The elastic quick-release cords on the shoulder straps provide quick access to poles on the go without having to take off the backpack. This way, you don't have to slow down your pace.
