Mammut Lithium 20 zaino 20 L nero, blu

With a 100D Nylon Triple Ripstop main fabric that shrugs off abrasion, the Mammut Lithium 20 is built to endure rugged trails and alpine scrambles. Its 20-litre capacity and CONTACT VENT™ back system keep you cool and balanced, while the PFC-free DWR finish adds weather resistance without harming the environment.

Overview

Designed for hikers, trail runners, and mountaineers, this unisex pack combines lightweight durability with smart organisation. The top zipper opens wide for easy access to the main compartment, and the hydration sleeve accepts up to a 3-litre reservoir (sold separately). Five external pockets—two stretch side pockets, two zippered hip belt pockets, and a zippered front pocket—keep essentials within reach.

What stands out
