Gregory Alpinisto 50 Backpack Medium zest orange

Lighter, tougher, and more technical than ever, the Alpinisto 50 brings the best in materials, features, and construction for demanding alpine situations. Its top-loading design also offers full side zipper access with a split-top skirt design, an oversized reinforced front panel crampon pocket, and a removable lid compartment for smaller items. A lightweight alloy perimeter frame supports heavy gear loads, or strips out along with the removable hipbelt and framesheet for ultralight missions.

Fusion Flex Suspension
The punched HDPE back plate made of 7075-T6 aluminium creates ideal wearing characteristics and optimum power transmission. The conical dual-density padding of the shoulder straps maximises freedom of movement. The High-cut Dual-Density hip belt can be worn with a climbing harness. The padding on the hip belt can be removed to reduce weight. The thermoformed rear wall adapts perfectly to the back. The anti-slip lumbar pads distribute the weight correctly on the hips.

Measuring the back length
Measure with a tape measure along the spine from the 7th cervical vertebrae (the spinous process is easy to feel from the outside at the lower end of the neck furrow) to the iliac crest (at the level of the upper bony hip structure). Measure two or three times to get an accurate result. If you are between two frame sizes, the smaller size is right for you.
