    Year-round mountain adventurer.

    Mammut's Lithium Crest 40+7 Backpack goes from overnight winter tours to summer weekends in the alpine with ease. Its Contact Vent V Frame combines breathable padding with the stability required for long approaches over rugged terrain. The back panel adjusts vertically to ensure a customized fit, and the top lid adjusts to accommodate more gear for longer adventures.

    Mammut made the Lithium Crest hydration compatible to pair with your hydration reservoir, and the detachable rain cover protects your gear from wet weather when needed. The bottom compartment stows compressed sleeping bags, and it's removable to reduce weight. There are gear loops for sleeping pads, carry loops for ice axes or trekking poles, and a plethora of pockets for smart organization.

    Quality Pack

    • Familiarity: I've used it several times

    I will go ahead and agree with Brian's review below, this is a great, well designed quality pack. It is quite comfortable and distributes the load nicely.

    Well thought out pack.

    • Familiarity: I've put it through the wringer

    Love this pack. Its well thought out in its features. It also fills the niche of the in-between size. The in between size can be good for summer trips, or simply going light in any season. The suspension is good and carries the load well.
    Favorite Features:
    • Adjustable back - A lot of packs in this 40L size range are one size fits all.
    • Front Pocket - Nice big pocket that stretches to store quick access items. There outer most face is not mesh, so I don't have to worry about tearing holes when I drop it on the ground.
    • Rain Cover - Cover is included. Always a plus.
    • Mesh Pocket - There's a mesh pocket inside the pack that helps for some of those extra items that you don't access a lot, but still want to stay organized.

    All in all, Mammut makes great packs.
