Mammut Alto 28L Backpack Black, One Size

What Our Gearhead(R) Experts Are Saying: "I've used the Alto 28L for everything from day hikes to bike commutes, and it holds up incredibly well. The ripstop fabric sheds light rain, and the detachable mesh pocket is perfect for stuffing a shell or wet gear. It's got a mountain feel but works just as well in the city." We like our gear to be ready for anything, and the Mammut Alto 28L Backpack delivers that versatility in a clean, everyday-ready package. Borrowing design cues from Mammut's alpine packs, the Alto uses tough ripstop polyester to fend off abrasion and resist light weather, while the spacious 28-liter capacity gives us room for hiking layers, lunch, and a laptop without compromise. The wide U-shaped zip opens to a thoughtfully organized interior, including a padded sleeve for a 15-inch laptop and enough room for a change of clothes or trail essentials. A detachable mesh pocket lets us stash a wet layer or keep small items close at hand, and a side pocket offers quick bottle access. Whether commuting or summiting, it's a pack that adapts to our everyday adventures.
