Mammut Lithium 32 (2012)

Designed as a multi-function sack for use when running, hiking, skiing or tackling via ferrata routes, the Mammut Lithium 32 is pretty light at 810g, but it retains a full set of features to ensure it is also practical on the hill. The back system is stripped back though with very simple raised nodules to provide an air gap and some cushioning. Mesh shoulder straps and a hipbelt mould to the body rather than providing padded support. This allows the pack to hug you, but it is not as comfy as other, heavier, designs. The body of the sack is great though with plenty of handy features. The stretch wand pockets on the side and compression straps are useful, as is the front stretch stash pocket. The single-clip lid is fast to use and neatly covers the top opening to the main compartment. I’d like a deeper snow lock extension on the main compartment, but as the lid is well-designed this is not a major problem. In use the Mammut Lithium 32 is a practical lightweight option but, as would be expected with packs where weight is stripped back, it’s less comfy than others.

The Mammut Lithium 32 is an ideal lightweight sack for many activities including hillwalking and superlight backpacking, but heavier sacks are more comfortable and most likely more durable.
